SVG import - broken paths

[linus.nikander]

I'm trying to pocket 2d-mill a somewhat complex pattern. When I select the pockets I want to mill some of them lead to crazy results. The pattern is created in Illustrator. I then export to SVG (with maximum precision). Since the shape in illustrator is the inverse of what I want I surround it with a box and get this:

I then extrude what is marked as blue (do I have to extrude to be able to mill btw?)

In CAM-mode i add a setup and start selecting things i want to mill. This picture is what it looks like when things are ok (or at least when i perceive them to be, I'm pretty new at this).

I then add a single pocket to my selection (the one to the left of the arrow in the upper middle part of the overview). 

 

When i click ok the following tool-path is rendered

Am I doing something apparently wrong? If the answer is that I have to repair the paths in 2d (would make sense), how do I detect the problematic ones and how do I repair them?

Hi Linus and welcome to the forums!

When you are selecting geometry you can pick where you want the cutting area to be. If you are selecting a circle it can be either inside or outside of it. The blue field indicates the cutting area. You can inverse the cutting area by clicking on the red arrow besides the blue contour line. Fusion is smart enough to choose the right cutting area most of the time but sometimes you have to change it manually.

Watch the video below that I made for you.

What a lifesaver thank you!

A couple of follow-up question (or maybe I should start a new thread?).

• Does it matter if i select the bottom or top circle of a particular pocket? As the shape is extruded there is a top and bottom available
• Is there any way to force the tool to mill/drill a hole even though the diameter of the pocket is smaller than the bit diameter? Or do I have to solve that by enlarging the pockets?
• And if I have a 1mm bit, which parameters do I set, and to which value(s), in order to allow pockets of exactly 1mm? I'm having trouble milling holes of the same diameter as the bit. I get the following error "

  One or more pockets were not machined because they are too small to be reached with given ramping constraints!" . I've tried changing the constraints but can't seem to get it to accept something which has the exact same diameter.

What material are you machining?

If you can share the file I can go over your questions in a video.

Haven't made up my mind but wood, mdf or acrylic. 

Here's the file.
