Controlling import tolerances question

Post by paulmoore »

The first picture is the model and the second picture is of the vectors created after created vector from boundaries
Normally at this point I would ungroup, deselect the profile edge to isolate the circles for a pocket cut.
I am wondering if there is a setting to alter the import tolerances?
As can be seen the vector has a gap on two of the holes and not the other. Hopefully I can modify the bitmap creation specifications.

Rather than using the boundary create you could use the bitmap trace on the 2D greyscale. That's how we used to do it before the boundary trace option was added. There are tolerance settings on that tool.

Can't you export matching vectors from the software you're using to create the model?

Could it be that either the radius or the center of radius isn't the same between the circles and the rest of the curves? Looks like it.

@Tex_Lawrence,
Here is the washer node section of my Archimatix graph in Unity so everyone can see the symmetry is there.

@Adrian,
Thats a good idea to try. I have had to do other work arounds in pioneering this Unity/Ax to Aspire workflow.
I did expand the ring depth by 5mm to fix this but I hate to keep nudging the design away from my initial measurements.
The two paths are the vectors and the bitmap reading. No, I have not tried to export vectors from Unity only FBXs and OBJs. So that is what I have to work with.

So far the toolpaths all line up in the routing. The final profile is not done yet. The graphic shows a side view of what the layers look like.
The repeatability is there as my washer hole radius was shy by 2mm. I caught this after the washer pocket route. I increased the radius in that washer node, transferred the file to Aspire and recut a second time with no problems.
Each sheet takes 2 days.

I ask for myself and everyone else who doesn't know. Where is "boundary create" hidden at?

I searched the help and user's guide and could not find it.

Found it in Help, must of misspelled earlier.

"Create Vector Boundary Around Selected Components" is the full name. It's on the modeling tab.

What you show on the image is the same thing but done at import stage rather than afterwards.

Thanks for the clarification, been using it for years.

Couldn't tell from posts what you were talking about.
