SelectionFilterEnum filter for hatch selecting with "Pick" iLogic command

ReneRepina — Thu, 13 Nov 2025 11:16:16 GMT

Hello.

Does anybody has know which filter ("SelectionFilterEnum") to use in "Pick" command from "CommandManager" (code below) to select only "Hatch" ("DrawingViewHatchRegion") or the part that has a "Hatch"?

I have a feeling that it is not possible / implemented, but I ask anyway if anybody may know this.

What we want to do is to run the iLogic rule, which has "Pick" command and we would click on "Hatches" we want to changed with specific parameters. Alternatively we could also click on the part that has a hatch, but first option is better.

Code example:

ThisApplication.CommandManager.Pick(SelectionFilterEnum.kDrawingViewFilter, "Select object.")

Best regards,

Rene Repina

Hello @ReneRepina ,

there is rarely support for drawingview hatch-objects.

If you use kAllEntitiesFilter you can't select a hatch-object.

If you select a hatch at the UI and use Thisapplication.ActiveDocument.Selectset(1) you get Nothing!

I use Pick with kDrawingCurveSegmentFilter to get an DrawingCurveSegment.

From this you can get the DrawingCurve and furthermore the SurfaceBody and the DrawingView for the selected object.

Finally loop through the drawingview's HatchRegions and check if the hatchregion's SurfaceBody is the drawingcurve's SurfaceBody.

If thats True, you have the HatchRegion from the selected DrawingCurveSegment, yeah!

Hello @cidhelp .

Yes, I though so... ☹️

kAllEntitiesFilter --> I have tried that, but as you already said, no luck.
Thisapplication.ActiveDocument.Selectset(1) --> It is really strange this goes to "Nothing", since it is a "DrawingViewHatchRegion" object? Bug?

Thank you for answer and suggestion! I was going into this direction, but I did not want to. 😅

Autodesk would say, thats not a bug it's "as designed, go to Idea Station..."
