Road map carving into 3D mesh - CC Pro?

[jtclose (Jim Close)]

I am looking to cut roads into a 3D mesh.

I found this link

Contour with 3D Z?

If you have a 2D overview geometry aligned with the 3D model along X and Y, you can subtract it from the design, then disable that layer when cutting the 3D model, then enable and use only that geometry for a 3D Finishing toolpath. Please see:

It seems to say you can subtract a SVG from a 3D component in CC Pro.
I am assuming this could be an imported STL file (terrain) and a SVG (roads). It projects the SVG paths onto the STL mesh and creates an entity that you can run a tool path on.

It is up to you to align/scale the two files.

I think this is CC pro only, which I do not have.
If this works I am buying CC Pro.

Has anyone confirmed this ?

I have spent the last couple of days trying various techniques to create a 3D path without success. I know Rhino will do it, but that is a bit of a $ jump.

I tried MeshLab ( importing 2D objects not happening ).
Blender maybe an option.

I have Fusion, but you need to have the Convert to Solids enable ($) via an Add On.
That is needed to project the curve.

I have a free OnShape account, but I have an issue dumping huge polygon files to it ( I don’t want to piss them off ). The imported file needs to be resurfaced anyway to generate the 3D curve.

Thanks,

Jim

Terrain Relief Model - Drawing Paths

I thought that we had discussed this previously. Anyway, wouldn’t it work in Carbide Create Pro to: import the 3D model: [image] Draw the path as an outline which is ~10% wider than a small/narrow endmill: [image] Subtract that from the model as a shallow path: [image] [image] Then, cut things as normal: [image] [image] [image] which all previews as: [image] Then, select the geometry: [image] and assign a 3D toolpath to it: [image] and one gets a toolpath which foll…

I even commented on that thread ! Ouch …
Thank you !
