SC4 Devotion Forum Archives

Hello everyone,

Watch this space. The RHW Interchange Guide will be expanded and reorganized into this new child board in the NAM How-Tos and Tutorials section. The current thread will eventually be broken down and put back together into several threads in it's own section of the site. There will be a sticky thread or two containing the basic information and whatnot.

The current interchange guide will remain in it's entirety until everything has been moved and structured properly, so there shouldn't be any worry about missing content as the transition is taking place.

Link to the RHW Interchange Guide thread: http://sc4devotion.com/forums/index.php?topic=6843.0

If you have any questions or comments about how it should happen, or about the guide itself, feel free to post in this support thread.

So, question...

http://bit.ly/GZ1OvS

This interchange...any suggestions as to how to go about it with RHW? I've been trying to create a "realistic" philly for forever for a MD, and...this interchange trips me up every time. I don't want to just cheat it and use a trumpet interchange, because it's not really a trumpet...it's just - what it is.

It's a weird T Interchange with a few modifications to permit local access and Centre Merging to the South.

You can create an approximation of the interchange, but you can't do a replication. Your best bet would be to substitute it for a FlexFly T-Bone Interchange.

Something along these lines: http://sc4devotion.com/forums/index.php?topic=6843.msg352620#msg352620

You will need to change all of the overpasses to EMIS as there is no ERHW-4 FlexFly.

Hi guys, here´s a question what slope mod do you use/recommend?

Thanx!

Thanx!

There's two I would suggest:

Ennedi Slope Mod: http://sc4devotion.com/csxlex/lex_filedesc.php?lotGET=1512

The RHW slope mod: http://community.simtropolis.com/files/file/27617-rhw-slope-mod/

Hope that helps! :)

Thanks for the links, about the RHW Slope mod, does it create slopes for all network s? or just RHW?

Ennedi's slope mod handles all networks.

The nwelsh RHW slope mod that was recently re-uploaded to the STEX just handles RHW slopes, not other networks, and was originally designed to supplement older slope mods (e.g. BRF) that didn't include RHW slope modifications.

Is it possible to make a stack interchange in sc4? My city needs a high capacity interchange but there's not enough room for a cloverleaf.

It is, but if you don't have enough space for a Cloverleaf, you certainly don't have enough for an RHW Stack at present.

It is, but it isn't practical to create a guide at this point in time. It would be exceedingly long and complicated, and would use components that are not RHW (2 'levels' of avenue tunnels) which I don't like to use, or use minimally.

In addition, the stacks made by the current version of the RHW are not realistic examples of the real world, which the 'real' highway aims to recreate. Perhaps later releases will contain enough components to create such junctions both easier and more realistic, and are perhaps less space-consuming as well. (Stacks are supposed to use limited space.)

Stacks are kind of the "holy grail" of RHW development--we've been working toward them for the past 5 years.  In order for it to really be feasible to build stacks with the RHW, we're going to need to have additional heights of Elevated RHW in place (already in development for the next release) and additional variants of FLEXFly to go along with them (some in progress already). 

I suspect once the new release comes out, there should be enough content to make stacks.

-Alex

That is correct Alex. Right now the RHW can comfortably support 3 levels (see photo below), so only one more is needed to create the classic 4-level diamond stack. The content provided in the current version comes awfully close to being able to create content like this, so I am convinced the next release will allow us to find a way to make them. Then, perhaps the process to make such a junction can be simplified so a basic, easy-to-follow guide can be created.

This photo shows that the RHW can support 3 levels. The lowest, or 'sunken' level can also be swapped with tunnels, although your RHW will need to be transitioned into another road network :P.

A subsection for stacks has already been incorporated into this guide so when the time comes, stack interchange guides can be easily added.

-Ryan (Haljackey)

Thanks, I'll try experimenting in a blank city to see if i can make a compact stack in RHW.

With RHW 5.0 out, I believe it is now possible to make a RHW stack interchange without using tunnels.

I think. I may have to spend some time tinkering around.

Still no. Unless you consider a DDRHW diamond a 3-level interchange, or you use tunnels, or something like what Ryan did above.

I've spent a lot of time tinkering with the RHW but never came near the possibility of building a classic (diamond) stack.

Well, we have L0, L2, and L3 MIS now, as well as L0 and L2 RHW4. Combine that with being able to sink stuff into the ground (which an engineer would likely do anyway), it might be possible.

No we don't. The only reason we have L0 to L3 and L2 to L3 stuff is to access the upper deck of DDRHW-4. The current version of RHW doesn't have any draggable L3 stuff, plus the new height transitions are starterless.

It's still L0 and L2.

Not sure if this is the right place but can someone help me with this one?

I´m trying to connect the diagonal RHW-4 to diagonal ERHW-4 using diagonal one way ground to elevated pieces, like this:

Thanks for the help

@ solovinodelmal: That happens because a diagonal OWR-to-RHW transition does not exist. You'll have to curve your routes to an orthogonal direction to make that transition and then curve them back to a diagonal direction. That is (currently) the only way to avoid the issue you're having at the moment.

bummer... I could swear I saw a picture of it somewhere.

Thanks Hal

so here´s what I did instead:

I like it better, sometimes simpler solutions turn up to be better I guess

Okay, I need some help with interchanges.

Basically, I need to make a T-interchange. The difficult part?

The left arm and the leg are the highway that continues. The right arm is the terminating highway.

Yes, it's a T-interchange, either semi-directional or directional, on a curve.

Anyone got an ideas? I made one, but it was really, really ugly and not elegant at all.

Oh, and to top it all off? I need it to be elevated.

Section 14 (http://sc4devotion.com/forums/index.php?topic=14073.0) of the guide covers T-interchanges. Perhaps you'll find a few pointers there.

In addition, would you mind posting a screenshot of the area? It's one thing to read about your situation, it's another to actually see it.

I'll post a screenshot later today.

I do know that Section 14 covers T-interchanges, but so far all the variations I've tried haven't worked well.

@ solovinodelmal: There is indeed a way to get rid of the stub at the end of the ramp. (*searching for old post of mine - found!*).
Just do the trick as described below.  ;)

Edit2: the strange loop (from the east) is basically because of the lack of diagonal parts with the RHW-4 and the transition to MIS....

For building a diagonal transition from RHW to MIS (and vice versa) you can make use of the OWR2-OWR1 diagonal transition puzzle piece.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi240.photobucket.com%2Falbums%2Fff211%2FMcDuell%2FSC4%2520stuff%2FDiag_RHW_MIS_1.jpg&hash=4acd961a8167b2b8b1a5b758909350db1e11a291)

1) Lay down the OWR2-OWR1 transition piece and prolong the stubs with OWR. Then, create some rail crossings.

2) Bulldoze the OWR right before the railroad crossing. This leaves you with just the rails.

3) Now bulldoze the leftover rails.

4) The finished transition should look like this.

@ dragonshardz: This is a quick and dirty idea which I had after reading your post. Could this be about what you were looking for?  :)

Good enough for government work. That's exactly what I was attempting to do.

I'm sorry to bother you, guys. Long time SC4 fan, embarking on very belated first time serious use.

Hoping that someone could tell me or point me in the right direction regarding getting RHW to resolve to MIS pieces. Sometimes it works, sometimes it doesn't. I've read NAM documentation and RHW Interchange Guide. I've read that they can be sensitive to slopes, and sometimes the right piece simply doesn't exist. In this case though all I'm trying to do is a simple straight diagonal connection between 2 MIS puzzle pieces (FAMIS to diagonal transitions), everything looks like it should match up, and it does, except the connection remains as unresolved RHW.

Has anyone put together a more detailed document regarding these (ie a 'guide for noobs and dummies' like me)? Does it make a difference if I'm dragging RHW to the MIS piece, or dragging the RHW from the MIS? Any help would be greatly appreciated.

MIS will only form an override form a Puzzle Piece that has a Starter on it. To my knowledge, none of the Wide Radius Curves or FARHW stuff (Except ramp interfaces) have starter pieces on them.

There should be some MIS fillers in the RHW Starter Pieces menu, somewhere toward the end.

Aha. Diagonal MIS filler 1 sounds like it should meet the requirement. Many thanks jdenm8.

I have to say the tutorial for Section 15.2: Diverging Partial Cloverleaf Interchanges has reduced me to tears and put serious doubts in my ability to function as a human being.

I can't get my ramps in the same places, which makes everything take up more space.  When I do an override ramp it comes out as a European texture even though I don't have a European text pack installed. I can't get an RHW4 lane shift to match the same direction as the guide. 

Please tell me the guide is outdated so I can have some confidence in my ability to function a productive life.  Maybe a video of the production would be helpful.   

Don't despair ;)  Most of the guide is technically outdated, and although many designs should be possible to replicate with the latest NAM, that's not a certainty.


Cheers
Willy

Actually no part of the guide is outdated. The first entries were made back in the RHW 3.0 days, and those setups are still possible to make with NAM 31.

---

Regarding that guide in section 15.2, I did not make it (CrimsonPhoenix did) so it might be a good idea to send a PM to that member.
-A few tips I have for you is to ensure the ground is totally flat, and try plopping pieces in different orders to see if that omits the problems you are experiencing with spacing.
-I have no clue what's causing the Euro textures showing up. Try replicating the issue with just the NAM installed in your plugins. If it still happens it might be something worth reporting in the Bug Report Thread (http://sc4devotion.com/forums/index.php?topic=15803.0).
-Regarding the lane shifts, try rotating it an open area to understand what spot your cursor needs to be. For some, the cursor needs to be at the bottom of the piece, for others, its at the top.

It's one of the more difficult guides, especially if you're not a veteran FULP user (Can't say that I am either). The guide was made with RHW 4.0, so you can use some new pieces from 5.0 and NAM 31 to try and get around these issues and make your junction more unique.

Anyways, hope this helped you out!

Hi! First of all, thanks for all people! Thank you very much for all this tools! You made my game experience up to 10!!! Im sorry about the way i write, but I'm not a native english speaker!

Ok, now maybe you can give me a hand with this issue im having! I'm tring to build the Standard Two-Level Cloverfold Stack Interchange!
http://sc4devotion.com/forums/index.php?topic=14070.0 (http://sc4devotion.com/forums/index.php?topic=14070.0)
Its the second guide in that thread.

So i get to this point, (https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi142.photobucket.com%2Falbums%2Fr101%2FUltraPerfectCell%2FHybrid%2520Stack%2520Interchange%2FHybridStackGuide-Jan18001295046371.png&hash=241b2a41128d6833efc3c184616a67263767204c)

And when i try to drag the MIS RHW under the bridge, i get a problem. The MIS RHW next to it, the one that has the ramp, turns into a RHW2, just before hiting the ramp, and i cant fix it. I tried to build it in a diferent order, but it still happening. Dont know what to do, always get this problem at this point. Is there something i can do?

Again, thank you all very much for all this effort!

Hi,

I apologize if this is documented somewhere; I can't find it.

I'm trying to build an expressway with a one-way frontage road:

<<<<<OWR<<<<<<
     /           \
<<<<<<<<<<<<<<
<<<<<RHW6C<<<<
<<<<<<<<<<<<<<
------------------
>>>>>>>>>>>>>>
>>>>>RHW6C>>>>
>>>>>>>>>>>>>>
     \           /
>>>>>OWR>>>>>>

I've seen some screenshots on other threads showing this configuration (more or less), using the fractional on/off ramps connecting to a RHW4 road, which is fine, but at either end of the on/off ramps I'd like to transition the RHW4 road to OWR2 and I can't for the life of me figure out how. (I'm assuming, of course, that it's possible.) So:

                 \    /
>>OWR>>>>RHW4>>>>>OWR>>

The reason is I want to be able to put businesses facing the access road, but with RHW4 it's considered a highway so no road access.

Alternatively, I could live with using regular roads instead of OWRs.

Also, while I'm asking, when I use the fractional entrance and exit ramps, whether I use the RHW2 or RHW4 ramps, they don't draw correctly (they don't line up with the rest of the RHW6C lanes). Any ideas what I might be doing wrong?

Thanks!
ST

First of all, pictures would be immensely helpful. Unfortunately for many of us that are familiar with RHW, some of these problems we solved long a go on our own and are unfamiliar with problems new users face.

Secondly, provided that you transition your FARHW-4 to orthogonal first, you may simply drag a OWR-2 out of the RHW-4, and it will auto transition, no puzzle pieces or anything like that necessary.

Also, I don't recall there being FARHW ramps for RHW-8C to RHW-6C and RHW-4, but I could be wrong. You're probably using the RHW-10 or 8 S split, which would cause the ramp to not work at all (since the pathing would be broken). Make sure you read the description of the piece and/or can see the piece before you put it down. If the preview doesn't look right, chances are it won't change once you plop it.

A lot of the RHW has new draggable functionality with the NWM (which you would also have installed [in an ideal situation]), where you can drag road out of the RHW 6C and it will automatically change to TLA-7 with out any starter overrides (or OWR-3 out of RHW-6S, or Avenue out of two side-by-side RHW-4, etc). You can get familiar by experimenting in some blank, flat test city tiles, and see what's possible.

Hi,

Thanks for the reply (and for everything else!!!). I'm not at my home PC right now but I will try those things this evening. I thought I tried dragging OWR-2 out of RHW4 (orthogonal) and it didn't work. I'll try again.

I'll check to see what I have installed (I didn't install everything in NAM 31.2 but almost everything) and take some screen shots whether I figure it out or not.

Thanks again,
ST

Hi,

I checked and I do have everything installed. I cannot transition an orthogonal RHW4 to an OWR-2 road. See the attached screenshot:

(https://dl.dropboxusercontent.com/u/11673753/SC4SS1.jpg)

Here's a picture of what I'm trying to do (using mostly standard SC4 highways):

(https://dl.dropboxusercontent.com/u/11673753/SC4SS2.jpg)

...except I'd like to make the turnarounds smooth curves (preferrably OWR-1) and make the on/off ramps look more realistic.

Thanks,
Peter

From the appearances of your screenshot, that's because you're trying to transition over the starter.  The starter is a dead zone for that sort of thing.  Drag a little bit RHW-4 out of that starter the other direction, and then try the transition.

-Alex

In addition, there are parallel OWR ramps for ground Maxis highway so you don't have to use road there. Hit the tab key until you find them.

That's exactly what it was! I was trying to do it from a starter. Doing it from the other end worked fine :)

I'm facing a daunting (for me at least) NAM project and I'm posting it here for any tips or insight that the pros might have to offer.

Reconstructing my adopted hometown of Phoenix will involve several major interchange constructions, a few of which (4-level stacks) can't be done correctly with the current NAM. No biggie - I'll can compromise or wait on those. However we have one particular junction not so cut-and-dried. At the Mini-Stack I-10 (eight lanes) takes a relatively sharp 90 degree curve, while spawning one six-lane freeway to the north and a six-lane loop to the east:

http://en.wikipedia.org/wiki/Mini_Stack (http://en.wikipedia.org/wiki/Mini_Stack)

It's not unlike a diamond stack, if a stack traded proper freeway for more ramps. Anyway, would it necessarily translate into the labyrinth of MIS appearances suggest? Unrealistic? If not, any tips on how to proceed?

Thanks!

Can anyone pelase help me? I made a pair of rhw4 and now i'm having trouble ending the rhw4. I want to connect it to an avenue or a road but I just can't because there are no puzzle for me to merge my two RHW4.

Is it possible? or do i have to change my RHW?  ()what() I tried using the RHW6C at first but I was having trouble using an elevated exit ramps why i used two RHW4 instead and now i can't even end the line or at least merge it with other roads/avenues. i have ran out of ideas :'( :'( :'(

Firstly, I notice that there's a starter at the end of the ramps there: drag the RHW out at least one tile to get a stub.

Secondly, Puzzle Pieces are on their way out, and in this particular case there has never been a puzzle piece for that situation. Typically the advice is to try everything, not just puzzle pieces. This goes for all networks, but the RHW and NWM in particular. Unless something is explicitly unsupported (like diagonal intersections for the NWM), it's always worth it to try all possibilities.

Finally, the answer: You want to connect an Avenue to the RHW-4, right? Then simply, after creating the stubs in step one, drag an avenue into the RHW. It lines up and transitions perfectly, sans puzzle pieces. You can do similar things with the OWR-3 into 6s, and with road from a 6c network.

Again, experimentation is necessary for learning, and puzzle pieces are usually not where "hidden" features are to be found.

Also, you messed up the direction of the RHW. The yellow line should point INWARDS, not outwards. If you want it to properly point outwards, you need to install the Irish/South African RHW textures from the NAM installer.

Um, I noticed that, too, but since the paths are correct, wouldn't that imply that he either has it installed (and JPEG compression makes it look American in reverse) or that it's just installed correctly and not an issue?

EDIT: Nevermind. Just noticed he's in LHD.

thank you all for the response. I'm using LHD because that's what we use here in our country. I tried dragging an avenue to connect it to my RHW but it's not working. It only shows red mark which means that it cannot be done. I really tried everything that I know of. I still can't seem to solve it.  ()what()


Edited:

I somehow able to drag the avenue to the RHW ends. I'll try to experiment with it again hopefully i can come up with something.

Thank you for all the responsess  :)

apologies for probably a dumb question but just started using rhw and struggling though it.

where are the ramp pieces to get an exit/entry to mis off of a section of FARHW ? There is a menu section called FA ramps where id expect pieces for this, but all the pieces dont seem to be angled so I can put them on top of my section of farhw 6C.

what am i missing ?

thanks

There's no such thing as a dumb question, especially when it comes to things like this.

Some FARHW exits had been made (With Orthogonal and Diagonal MIS ramps) but they are not in the public release.

You're not missing anything, because they're not there to begin with.

To clarify further, the FARHW Ramps button is for ramps that are FA, and aren't for ramps off of FARHW, like a FAMIS to an ortho RHW-6S.

Nice to know some true FARHW ramps are being considered for the future!

thanks for the responses guys, nice to know, was convinced i was just doing it wrong !

I'm having trouble with SPUIs.

Here I am following the guide:

(https://dl.dropboxusercontent.com/u/204454/SPUI%201.jpg)

When I drag 6s RHW through the SPUI, parts of the SPUI disappear.

(https://dl.dropboxusercontent.com/u/204454/SPUI%202.jpg)

I've tried an awful lot of stuff to get the parts to stay without any luck. I have a similar problem building an SPUI under RHW4 L2. When the RHW4 L2 is dragged over the SPUI as in the guide, parts of the SPUI revert to avenue. Any ideas?

There was a massive code rebuild for the RHW in NAM31. A major problem was that we could not update all of the content available. What we could update, we did, but some things like FlexFly and FlexSPUI weren't, and are unstable as a result. Try using different distances between the SPUI puzzle pieces and the through RHW. I think a One-Tile gap is the most stable configuration.

Thanks for the quick reply, I'll try alternate configurations.

If you have height transitions right next to an RHW-6S without leaving a one-tile gap, it looks really weird because the concrete barrier of the height transition appears to be protruding into the far-right lane of the RHW-6S. (this is because part of the right lane and the shoulder of the RHW-6S overhang into the adjacent tile) So basically, it would look better anyway if you left a 1-tile gap between the onramps and offramps and the freeway.

hello everyone I am new to RHW and interchanges and i need some help...I am trying to do an elevated diamond but everytime I try to connect the MIS ramps to the interchange on the overpass the ramps turn in the wrong direction and it wont let me place them..i am using a completely flat surface...any suggestions?

Clear the area, place the ramps first, and then come back and connect everything else.
