Hey, all!
Just like many other posts that I've read, I am new to FreeCAD and am having trouble getting a logo extrusion cut into a basic cylinder. After importing the .svg file of my logo, it appears as over a hundred paths. After scaling it down to my required size and converting into a single sketch, I extruded it into a 3D shape and aligned it with my basic cylinder. The various tutorials and videos I have reviewed each have slightly different methods for cutting the extrusion into the shape, but each time it fails. Any help would be greatly appreciated! The svg, pictures, and system info are below.

Hi and welcome to the forum!
You should upload the FreeCAD file as well, so that not everyone has to start from scratch.

A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.

Re: Unable to cut .svg extrusion into basic shape
Part|Check Geometry on Extrude says Wire847 and Wire848 are self-intersecting - so they can't be extruded.
In the python console, I put
Python indexes from 0, wire names from 1.
This identified the problem. I went into Sketch, dragged the offending vertex so I got a non-intersecting closed loop and saved.
I increased the extrusion length to 5.1 mm so it stuck up above the Fillet and Part|cut.
Resulting file too big to upload.
In the python console, I put
Code: Select all
shp = ActiveDocument.getObject("Extrude").Shape
Part.show(shp.Wires[846].copy())
Part.show(shp.Wires[847].copy())
I increased the extrusion length to 5.1 mm so it stuck up above the Fillet and Part|cut.

Re: Unable to cut .svg extrusion into basic shape
with me it works perfectly, the only problem is that the upper faces are coplanar
Change the height of the cylinder, or of the logo, and make the fillets at the end

Re: Unable to cut .svg extrusion into basic shape
you can see the problem here with this face coming from nowhere (= from an 'error' in the path).
