need some help doing a chamfer

ddrumguy — Sat, 20 Feb 2021 01:10:42 GMT

hoping someone can help..

trying to do a chamfer on a body that was imported initially as a dxf (with the help of fusions dxf import tool) and not having much luck. the dxf was initially created by tracing with a digitizer board fwiw.

wanting to chamfer from the arc at the bottom (well from the line above it to the bottom of the body).

Thanks in advance for any help

Fusion doesn't do well with imported curves. even .dxf files. in this case you have a sketch made up of hundreds of little short line segments, and many of them are what's referred to as "near tangent". this chokes up many things in fusion like fillets and chamfers.

The advise has long been to rebuild imported curves with clean fusion curves before doing any solid modeling.

Hi,

On the screenshots you can see the state before and after connecting the lines and converting.

so how did you accomplish the removal of all the extra vectors?

He left out the part where h's running it through a different program.

your still left with unconstrained imported curves.

honestly, your better off drawing it in fusion.
