[Capture] Hello. I am looking for some guidance as to how to sweep the two shapes shown in the image along the compound curve shown. These shapes form an arch wrapped on a cylinder. I am very new to Rhino and I cannot get it to sweep correctly. Any help would be most appreciated! Thanks!

Hi Tom - please post a file with those curves. -Pascal

Compound Curve.3dm (1.1 MB) Here is the drawing. Thanks! Tom

Hi Tom - is this it: Compound Curve_Maybe.3dm (1.3 MB) Sweep1, from relocated profiles (rotated in Front) with 'Roadlike on the axis shown. Actually, @Tom_Haws - I take that back - Freeform Sweep1 may be better here, not Roadlike. File is updated -Pascal

Yeah, that is what I got too. From the top it needs to look like the attached image. The back face of the profiles need to stay vertical - no rotating back and the back face needs to cut back perpendicular to the front face at the ends. Top View: [Capture] Front View: [Capture2]

Yeah, you may end up needing to build this in parts if all the cylindrical faces need to stay parallel to the cylinder. Hm - is this any better: Compound Curve_Maybe.3dm (1.6 MB) ? -Pascal

Very Close! The only thing is the ends need to cut back perpendicular. Your model looks very clean. Did you just sweep it in one plane and then “bend” the whole model? I’m so new, I’m not sure if that’s possible :slight_smile: Thanks, Tom

Yep, there is a bend and it looks great. I’m going to head in that direction now. Thanks, Pascal for your help! Tom

Hi Tom - Bend may work as well but I used trickery - ProjectObjects.rhp (20.5 KB) See the attached plug-in. Download and unblock the rhp file in Windows Explorer, then drag and drop it onto Rhino to load it and add the command ProjectObjects The base objects are Revolved from the profiles; these…

[image] pascal: ProjectObjects Wow, that plug-in is great! Is it possible to add a Preview option so that the settings could be changed if necessary before building the end result? Also, history enabled maybe? :slight_smile: I noticed that the plug-in produces some weird looking results when…

Hi Bobi - a preview should be possible - initially it would simply be the result added to the document and deleted if you don’t like it and change the settings… that is the dumb but quick way, I’ll have to see if I can make a proper preview. History is not possible I’m afraid, outside of an actual …
