How to reverse image in MeshCam 6

Postby Mitch » Fri Mar 17, 2017 1:27 pm

I am new to it all.
I have a DXF file representing a gear wheel. When I open it in MeshCam 6 it appears reversed; what should be material is air and so on.
Is there a simple explanation?

Hi Mitch, and welcome to the forum. MeshCAM extrudes the imported DXF, so if all you have is your shape it will be a positive. Draw a box around the shape (it is most convenient to draw the box to the size of your stock so the shape is automatically placed) and then MC will extrude the material around your shape and leave the shape itself as a hole.

Looks like Randy is away. Is there anyone who can point me in the right direction?
I can not find any info on these anywhere. :!: :?:

Mitch, I'm sorry but I don't have Internet access on the weekend. There are no drawing capabilitites in MeshCAM -- you need to add the bounding box in your CAD program before you export the DXF.
