Polysurface / extrude issue

Hi,

I’m trying to make a surface to rough carve on a CNC a guitar top. I’ve had no problems extruding all my curves to the height I want but the last extruded curve won’t join to the rest of the polysurface. I get an error saying the surfaces don’t intersect. How do I fix that?

First make sure all your curves are planar.

It seems you extruded upwards. Try extruding downward and a millimeter further than your layer height so all parts clearly intersect

I don’t get it. I extrude up or down and past the XYZ plane and nothing works. I’ve copied the curve away from the rest of the model and it still doesn’t form a solid on extrusion. What’s the deal with that?? I don’t get what’s wrong with it

Maybe your curve isn’t planar and closed?

It is difficult to help without your file.

Can you please post a file with the problematic geometry?

why not provide everything that would avoid lengthy guessing games?

if its not planar use ProjectToCPlane, use the resulting curve to extrude, or used SetPt set to Z then extrude.

if either of the two dont work you it will not be closed, for a dirty workaround use CloseCrv. you might even have both issues, non closed and non planar but really guys just provide a file. just post the curve in question if you dont want to share the entire file… really not so difficult.

Sorry guys, my first post here, I didn’t think I could just post the file. Thanks for the CloseCrv command that has fixed my issue. I didn’t even know this one existsed. Thanks all for the help.
