Curve Follow - Finding Curves on 3D Model and Approach Move

#1
Hi, I'm trying to make a curve follow project around a 5mm tube.  I'm finding that the axial curves project well onto the surface of the tube but the radial curve seems to be lost in the part.  I tried to adjust the options but was unable to find a way to completely see the curve on the part.  As such, the curve follow project was telling me that it could not locate all the curves that I was attempting to give it.  I imported the curve from SOLIDWORKS but was wondering if I need to do it in Fusion or whether there is a way to fix the issue in RoboDK? Does it also have to do with the size of the part?

Another question I had was that the blade simuation path doesn't seem to line up very well with how I want the part to be cut.  It can't find a start point even though the tool is set up very close to the tube and the joints are updated to the current position.  Thanks!

I assume that it is necessary to improve the import accuracy by using smaller tolerance values.
In RoboDK on the tab Tools - Options - CAD:

In SolidWorks on the RoboDK plugin settings:

It looks like you need to set the TCP position correctly for your tool model:

Please take a look at the tool creation guide:
https://robodk.com/doc/en/Getting-Starte...#CreateTCP

Also, you can select surfaces (in SolidWorks, when exporting curves) that be used to calculate curve normals.
These normals are important as they will define the robot’s approach axis.

I guess the current normals are wrong:

Alternatively, you can use Tools - Modify curve to adjust the normals.
