My line was too complicated (too many segments)I drew it again in SU and used Weld and it's ok now. Thank you very much !!!:)

Ok, thank you What I needed was Weld, I've made it all but there's this last problem that the foot-bridge has holes, like on the picture..

cotty- what tool did you use to draw this curved line that is mine(:D)footbridge? I've imported the cad file - my curved line and I want to use plugin that you're using - Curvishear but it doesn't work with my line:( I see the difference here - when you click on yours it's already highlighted - the whole line and mine is in million segments, maybe that's why it's not working. Only a little piece is going up..

Thanks guys! You're great!! ))

Hi! Thank you so so much for a reply!!! I did ok with my second issue:) But here's the picture of the other one, my footbrigde is now flat as you can see and I want to make it quickly one floor up - to the red line, so only left end needs pushing up. I hope that it's one click to make it because I really can't think of drawing a raising path from my projection...There's this tutorial https://www.youtube.com/watch?v=PpvPl6Kis1s I'd love to do this that way, but it doesn't work with my complicated object Please help me! Thanks again for such a long answer!

I’m making a model of a footbridge, which is a line wavy, irregular, and it has a few dozen meters. I don’t know any plug-ins that would help create wavy line that I have in projection, so footbridge consists a large number of lines that make the ovals. Now I pulled it out of the projection so it is flat - I want to raise its one end on the floor above, because the footbridge is to go to the second floor. Does anyone know what function do this? The second question is whether it is possible to pull some part of object to other object? Something like a scale to pull one cube and fit but without changing the dimensions of the object. Please reply, thanks in advance!
