Translations:PartDesign Bearingholder Tutorial II/19/en

Use the sketch you created to make a Pocket and extend it to the face of the skeleton geometry that represents the bearing, minus 5mm offset for the wall thickness. For the second Pocket, you can use the option "Duplicate selected object" from the Edit menu to duplicate the sketch you already made (choose not to duplicate dependend objects if the question pops up). Then, select the face you want to move this sketch to, and tell FreeCAD to map the sketch to this face (this is an item on the PartDesign menu). After creating the second Pocket, you can look at the result from the bottom to check that you have a uniform wall thickness of 5mm around the contour of the skeleton geometry.
