I have a terrain mesh (solid) and another solid (red). I want to subtract the red shape away from the terrain such that I can place a set of stairs and patios etc on the terrain (already modelled).
I have tried draping the top face of the red solid and intersecting the shapes instead to then just hide the resulting area however this isnt selectable either.
Apologies yes I am using 2023, my mistake! Tinkered around a bit changing the red solid and now the terrain mesh is coming up as no longer being a solid, which I suspect is actually the case annoyingly.
I’m not sure why they’re there to be honest. I used point gadget v2 and a csv to generate the points. I then used Topo Shaper to make the mesh but the skirt option didn’t seem to work.
I have used the predecessor to point gadget v2 and never had these circles appear on the mesh before when using Topo Shaper but with this they did? I assume it’s been draped from the cones it creates?
Looking at the unextruded version of the terrain, the surface is full of holes! In the image below I set the background color to a purple shade to make these more evident. Most of them are circles, but there are also some other gaps. You will need to fix these before the version with the skirt will be a solid.
I would use a different importer to import the CSV as a point cloud so you get guidepoints instead of circles. Then use Topo Shaper to generate the terrain from the cloud.
Are there any you would suggest? The predecessor used to use guidepoints but this seems to use the cones. I couldn’t find a download of what came before annoyingly.
Edit: Would just putting a guidepoint into the cone componant work for Topo Shaper?
Looking at the cones more closely I see there’s a guidepoint already at the vertext of the cone. Edit the cone component and delete the cone leaving the guidepoint and then explode all the cone components leaving them in the group. TopoShaper will then work on them.
Thanks Dave, coming back to this project after a month away. Topo Shaper returns errors saying that the selection cannot use guidepoints which is what got me to the mesh before hand. Would I perhaps be able to use Enroth make faces or similar to quickly patch it up?
Which option did you use? I ran Topo Shaper on the point cloud after deleting the cones as I wrote and it worked fine. I copied it to a new file just to simplify things and it worked fine again.
It doesn’t work from points but it can use any geometry. It doesn’t require continuous contours. I once had AutoCad survey files with point elevations marked with text. I wrote an AutoLisp macro that added a vertical line to every text element, with length derived from its content. When imported into SketchUp the contours tool could be used to fit a surface over them. It only used the top endpoints and ignored the bottom.
Apologies, I misread it. It says it does not contain guidepoints.I am using the Trimesh terrain option. Have tried the points both in and out of a group and in a new sketchup file.
