mattedmonds Posted October 25, 2015 Share Posted October 25, 2015 I want to sweep a curb profile between the two edges of the terrain surfaces in the attached image. What tool is recommended to derive a wire object from the edges of the surfaces so that I can perform a 2-path sweep? Other ideas would be welcome.Cheers.

rob Posted October 25, 2015 Share Posted October 25, 2015 Use the Pick tool to select the desired sequence, and then use the Derive Segment with Join option... Link to comment Share on other sites More sharing options...
mattedmonds Posted October 25, 2015 Author Share Posted October 25, 2015 Thats how I've done it in the past, but was hoping there would be a better tool. For now, I consider that my fallback approach... and looking for something a little less tedious. Cheers. Link to comment Share on other sites More sharing options...
setz Posted October 25, 2015 Share Posted October 25, 2015 Duplicate all objects and ghost originals Project tool all to XY plane Object doctor to remove all coplanar segments to make each a single flat face Derive (extrude) 3D objects from all objects so they are taller than the originals Use intersection tool between each pair of original and new derived 3d objects to get a clean pair of lines from which to run your sweeps Link to comment Share on other sites More sharing options...
Alan Cooper Posted October 25, 2015 Share Posted October 25, 2015 I just did an experiment, and the following worked which didn't seem too tedious - once I discovered the successful method. Screenshot 1. Produced a 3d shape containing different elevations, with straight, radiused and curved edges, and used area pick faces, copy and paste into new file. [xy plane active] Screenshot 2. Delete any unwanted segments by area and individual pick as required. Screenshot 3. When satisfied select all, edit 'join'. Draw kerb profile. Screenshot 4. Axial sweep by first point [as positioned didn't work]. However, the profile is not as expected, it is inverted. I had tried various experiments with select first point, edit axis, nurbs tools etc, none of which were successful. Screenshot 5. SUCCESS! This is what worked: Edit segment tools - break segment; Derive tools - derive segments, shift-click the segment nearest the kerb profile first, followed by the second, click to finish and use it as the axial sweep profile using 'as positioned'. Copy and paste the result into original file. [xy plane active] I think the crucial factor which makes this not-too-tedious is the ability to select all segments required at once, join to make one object then break that into 2 objects with the line edit break tool before selecting with the derive segments tool which sets the direction for the axial sweep. Using a new file to do the work in helps too. As an observation, the video on axial sweep shows sweeping to create a 3d shape on a 2d plane only, it is good that FormZ is capable of sweeping along a 3d path and even better, from existing 3d geometry relatively easily.

rob Posted October 25, 2015 Share Posted October 25, 2015 Use the Pick tool to select the desired sequence, and then use the Derive Segment with Join option... That should be super quick and easy, no? How is that tedious? Thats how I've done it in the past, but was hoping there would be a better tool. For now, I consider that my fallback approach... and looking for something a little less tedious. Cheers. (Did you use the Segment Sequence topo / part level?)

Tech Posted October 26, 2015 Share Posted October 26, 2015 Matt, Rob's suggestions should work fairly quickly and easily. If you have a file where this is not the case, can you please post it so we can help further? Link to comment Share on other sites More sharing options...
