How To Modify The Path Based on .igs File-Steve Zhang-10-05-2022
Helllo,
I created a 3D path with igs file,but the arrow direction are all +Z.And because of too many points,I can't select the point I want.
How can I make all arrows normal to the path and toward outside?
RE: How To Modify The Path Based on .igs File-Albert-10-05-2022
You need a surface in contact with your curve so RoboDK can automatically extract the normal to the surface when loading the IGES file.

Thanks，one more question
How To Merge Different Types Path Files（igs,csv...） And My Part in RoboDK？
I made this path with a 3D CAD.
To export path,so my path has to be igs file,while the part is stp file.
even I chose 'move nested', it didn't work...
I wanted to know how I can merge my CAD part and path file in RoboDK.

Have them in the same reference frame, select both -> "Merge"

Thanks for your reply,Jeremy.It works,but new problem comes.
You can see I have a continuous curve around a cylinder surface, but its normal direction is discontinuous and changes abruptly at some points.I don't know why. How can it be improved?

You can activate this option to have more accurate normals when importing IGES and STEP files:
- SelectTools-Options
- Select theCADtab
- Activate the optionImport curve and point normals accurately

Hi,Albert
I followed your method,but it doesn't work.And it got worse somewhere.Is there any other way?
RE: How To Modify The Path Based on .igs File-Albert-10-11-2022
Have you tried importing it as a STEP file instead of an IGES file?
Can you share your 3D models? (STEP and/or IGES files)
RE: How To Modify The Path Based on .igs File-Steve Zhang-10-12-2022
No,I still use the igs file.
I can share my igs file,you can check.I made this igs file in Catia.

Are you trying to do some carbon fiber wrapping or something like that?
If so, this method might not be the best.
