Copy sketch (including hatch) as-is into a new sketch using Inventor C# API

[manasi_patilESZTV]

Hi Everyone,

As shown in the attached image, I have a sketch in Inventor that contains  a hatch pattern , Centerlines, Center Mark and geometry.

My requirement:
I want to copy this entire sketch exactly as it is (geometry + hatch+ Centerlines + Center Mark) into a new sketch programmatically using the Inventor C# API.

So far, I found:

• I can loop through SketchEntities and recreate lines/arcs in the new sketch, but this doesn’t bring the hatch.

• Hatch regions (SketchHatchRegion) don’t seem to provide a direct method to copy or duplicate into another sketch.

• There doesn’t appear to be a direct “copy-paste” equivalent in the API.

Question:

• Is there any way to directly copy a sketch (with hatch intact) into a new sketch using the API?

Any examples or workarounds would be highly appreciated.

Thanks!

Hi, 

What do you want to accomplish exacly ?

I see that we talk about sketch in drawing enviroment ? could you use sketched symbol functionality instead ?

I dont think it is possible to copy it all to new sketch but to iterate trough drawing hatches use SketchHatchRegions:

you can use it to check imputują and regenerate it in new sketch
