I have these two 2D shapes and want to convert them in a file for 3D printing. The final object is a cylinder with these shapes. Note that the each drawing is missing the vertical line to the right closing the shape into one path.
And ideas?
Have you ever looked at Autodesk's Fusion 360?
Depending on your situation, it may be free for personal use.
I was once faced with a similar problem and have used the loft technique in CorelCAD. You can read about 2D to 3D conversion in detail in this book: https://www.coreldraw.com/en/product/inside-corelcad-ebook/?pid=prod54hum3d
