[Solved] Can't fix 15m hole digging and overpasses

[making_out_in_aix 5]

Hi everyone,

After a 15-year ish hiatus, I recently got myself a laptop purely for the purpose of playing SimCity4 on. It's been quite fun sifting through the old and new content, reminding myself of everything I had as a teenager! 

Now... I seem to be stuck when using the 15m hole digger to build overpasses and transit at different levels. I don't recall this being an issue way back when, but I really don't know how to fix it. I've uploaded two images that show you what I mean. When I build, I lay the 15m hole digger first, then lay my transit (avenue, road, rail, whatever). However when I then want to add the overpass, I get this 'bump' where the transition is (which looks totally unrealistic), however then I also get this sunken terrain around the overpass, meaning if I place my eye-candy bridge, it gets stuck at this lower height and therefore doesn't look right. 

I don't remember having this trouble when I used to play, and have seen users posting city journals without this issue, where the overpasses are smooth.

Can someone give me tips or advice what I've done wrong?

Thanks so so much!!!

My first instinct is that you could be using the wrong puzzle piece  to build it. Does that piece say the word 'onslope' anywhere in its description? Other posibility is that you may have a separate slope mod installed thats loading after the NAM.

@CorinaMarie or @Cyclone Boom: Just flagging this thread as needing moved to Bugs & Tech.

@Whte_rbt

I skim read and feel it's prolly NAM related more so than a general SC4 Bug or Techy issue so I tossed into their forum.

Oh! Well, I've read it in full now. I agree. Hang on whilst I move it again.

Ah yes, sorry... entirely wasn't sure where to post it so took a bit of a guess! But I think actually I've worked it out now... I was using an 'on slope' piece, but think I should have been using a 'straight' puzzle piece. Thanks @Whte_rbt !! I kept scrolling through and tested first with a 'T-junction puzzle piece' and it appeared as the straight line I was expecting. 

Happy gaming!

No worries at all about that.

We can move things around when needed. (And good to hear you got it solved. I'll add that to the topic title.)

For everyone's benefit, here I have a screenshot illustrating the difference between on-slope height transitions and ramp-style height transitions.

 

This is actually quite a common mistake for novice players when first exploring the features of the NAM. Remember to use the ramp-styled transitions when you want the terrain to remain level when the network changes elevation. Conversely, use the on-slope transition if you're using embankments or trenches for the height transition.
