Edges between floating vertices? - Willy Tschager - 2019-10-09 Guys, honestly I'm a bit embarrassed - I really thought I knew all about authoring after all these years. However - I took the modelled head of the horse and created a flattened copy at x=0. I'd like to join every vertex at x=0 to X=a in the modelled head. Once I get all edges the modelled (main color) head will be deleted in order to get only the edges, which will be used as "altitude" guides for a patterned version. I could obviously do it manually but was wondering if it can be all done with just a few clicks. Any ideas? w. RE: Edges between floating vertices? - Philippe Hurbain - 2019-10-09 I think I have an idea, but I'd like to experiment. Can you share your "source" file?

So you want a template for the front view? RE: Edges between floating vertices? - Gerald Lasser - 2019-10-09 I think I've got what you want, using Edger2 and YTruder Code: 0 // start with this set of triangles RE: Edges between floating vertices? - Philippe Hurbain - 2019-10-10 Ah, I didn't got what Willy wanted. If indeed the purpose is to create a wall surface around an existing top surface, Gerald method is right. See also this very old tutorial http://philohome.com/isecalc/yttut.htm (but of course use more modern tools!), or this more modern one: https://www.wiki.ldraw.org/index.php?title=Stickers:_making_a_random_shape_one (granted, a bit different: since the top here is not flat, we must use projection on plane in ytruder instead of translation by distance).

I don't wanna "wall" the two shapes. I know how to do that. I'd like to have lines from every single vertex to x=a. I added a few manually in the example. ![]() Once I have those I remove all color 16 and bring in my pattern: ![]() Now I move all vertices from the pattern to a position where the lines start sticking through to get the shape right. I cannot simply project the pattern onto the current head as it would create an ton of tiny, tiny triangles. w.

Write up tomorrow! RE: Edges between floating vertices? - Gerald Lasser - 2019-10-11 Ah, I think, I got what you want. What I usually do in such cases I draw immediately on the template.
RE: Edges between floating vertices? - Gerald Lasser - 2019-10-11 I did a screen capture to show you how I would do it https://youtu.be/tBhhkdJSJUc RE: Edges between floating vertices? - Philippe Hurbain - 2019-10-12 (2019-10-11, 20:09)Gerald Lasser Wrote: Ah, I think, I got what you want.This is more or less the way I do 3D patterns.

I also tried to do it for the horse but it gets so laborious (and messy) that I prefer adjusting my pattern in 3D. There is no benefit from trying to follow the mesh. w.

RE: Edges between floating vertices? - Philippe Hurbain - 2019-10-14 (2019-10-14, 10:24)Willy Tschager Wrote: this looks perfect! how did you do it?Sorry, I thought the other methods for this pattern would be better (did you have a close look on my projection method here: https://forums.ldraw.org/thread-23710-post-34290.html#pid34290 ?) . So... - Open the shape in LDPE, and with Edger2 tool create lines/condlines everywhere (set flat surface maximum angle to 0). Create unmatched edges too. - Select everything (ctrl+A) and convert condlines to edge lines (C2L button). - Select everything again, launch Ytruder. Projection on plane, value=0, condline threshold=0 (edge lines everywhere), operation axis X - Select one surface, Select -> uncheck vertices/lines/condlines, then select -> all shown. Delete key to let only lines - Slightly more tricky part: view head in front view, manually select all top edge lines with a marquee, hit delete key. Done. Edit: This process creates a lot of duplicated lines, may need to cleanup in text window. RE: Edges between floating vertices? - Willy Tschager - 2019-11-24 The horse head is now at the PT: https://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/4492pw1.dat In the end the way I had in mind didn't work out as plant - still too much work to do and the result wasn't satisfying. * Moved the projection of the pattern at x=10 * Added Philo's edge file as subpart * Used the outer rim of Philo's file to get the border at the right distance * Brought in the existing 4492s00.dat - Animal Horse Head Side Surface * Moved sections of the pattern (mostly based on color) very close to the surface * "Merge To Nearest Face" * CRTL+E of those vertices which were reused in the pattern from the imported template w.
