Create a hole polygon
Hello,
I'm new to FreeCAD and I hope to find a good tip for my question here!
So, I have an SVG-file with a set of polygon paths, like this
In FreeCad I do the following:
1. Import SVG as a geometry (importSVG)
2. Choosing 'No' to the question 'Do you wish to use 96 dpi'
3. Select all paths and make 'Extrude'. Than I have a set of 3d solid polygons like this:
The question is: how to make each polygon as a hole polygon?
Thank you.

Hi and welcome to the forum!
- Select the extrudes you want to be holes
- make a Part->Union
- Cut the Union from the rest.

Re: Create a hole polygon
Hi chrisb,
thank you for the help! I've tried to do an Union, but Union does nothing - the paths looks like before:
I've also tried to add a Part::Thickness, and it work for one Extrude, but when I try to make it for all Extrudes via macro, I get the following result:
I also attach my svg https://we.tl/t-HAOvBYlAuO and macro https://we.tl/t-gQOFM80qEN.
What is wrong with the Union and Thickness?
Thank you.

Can you provide the FreeCAD file as well? And pleas on a filehoster that doesn't require registration.

Re: Create a hole polygon
Ok... Another try https://easyupload.io/73nxj0 - this is the result of Thickness transformation.

Re: Create a hole polygon
Select all the ones you want to use as the base and do a Union. Alternatively, select the ones you want as cutting tools and delete them, then union all the rest.
Re: Create a hole polygon
The result should look like , but for all the paths.

Re: Create a hole polygon
Thickness is very fragile and finicky.
Try this. Select all the top faces of the extrude objects and create a SubShapeBinder (green one) in Part Design (you don't need a body object). Set the Offset property to -.25 mm.
Extrude the binder in Part workbench, ticking reverse to true and length to 4.75 mm. You can then cut this new extrude from a union of the base extrudes. You might have to reset the color in the view tab for the extruded binder because it will be yellow.
