I exported a .stl from SolidWorks, and imported it into AutoDesk 123D Make. 123D Make has accessible parametric slicing tools for making press-fit kits from 3D Models.
Sophia warned me that when she used 123D Make to slice for
her project the exported files contained inaccuracies. 123D Make lets you specify the thickness of your material so that it can create press-fit slots of the correct size. Sophia warned me that this feature did not work correctly - the sizes of her slots were did not match the specified material thickness.
I knew to verify the slot size before cutting. My slot size seemed to be working correctly, but I experienced a different bug:
- Tolerance setting in 123D Make is Inverted
A construction option in 123D Make let you specify a tolerance for press fit instructions. The software documentation claims that increasing the tolerance value will make a looser connection. I found this value was inverted. Increasing the tolerance value in 123D Make actually made the slits smaller.
