Can OCCT fill closed contour with lines?

[jianbaoxia]

Hi Bros, I would like to fill a closed contour with lines. I don't find suitable tool. The closed contour looks like below:

Or should I build some planes, and get the intersection lines, it seems more troublesome and cost more resource.

Hatching can do the job. For that, you first have to build a face on your contour though. Then you can check how "Show hatching" command is implemented in Analysis Situs (select a face, right-click, then "Show hatching"):



Here is the implementation: https://gitlab.com/ssv/AnalysisSitu...siVisu/pipelines/asiVisu_HatchingPipeline.cpp

Maybe you can use BRepOffsetAPI_MakeOffset when there're no loops in your contour.
