Help| creating a parking ramp with 2 curves

clubber2k

hi fellow sketchers

I have a simple task in words, but a hard one for me in sketchup, I looked at the forum and youtube for tutorials or plugins but most of them are random complex shapes and not accurate continues roads which splits up to two directions along the way.

In action I need to make a solid continues ramp which acts as a parking area. from the entrance there is a simple curve but at the middle it splits up to two roads (heading left and right) plus, I have parking spots along the way which need to at the same slop.

simplified plan added in jpg. numbers represnt therotical rise in slop.

can you please advise on how to do, or refer me to simple free plugins or a similar tutorial you know of?

thanks in advance,
sketchuper.

you need curve shear

this looks like a 1 to 2 slop, since I need to be at a specific hight at the center (2) and continue the slop from there (up to 3) I'm not sure this will do but I will give it a try!

if theres anything else of that matter I would appreciate the comments

Here's simple version - why do you need 'curves' - it'd be easier to build as a series of ramps and platforms

thanks TIG (I use some of your plugins sometime ) for the detailed illustration!
beautiful simplicity

that is how I was planning on doing it butI want FM to smothly continue rising while turning.
when building this way FM is a flat road with no slop which isn't excatly what I want.
I need the ramp to rise smoothly from the start of F0 to R11&R22.

if curve share won't work I'll go to this way.

any other thoughts ?

Thanks for everyone's help, I did it the "hard" way with the awesome curviloft plug-in, and draping the CAD plan on to it.

here is an image of the model base which(with the road the ramp and the parking) has small but multiple important curvatures.

now theres something to build on..
