"rest edges" of a solidworks 2019 sketch

[Aurelia]

Good morning, my name is aurelia, I am a beginner of solid works and I would like to give me advice if possible. I have to print 3d a little game like the kids, where you have to put a figure in the hole with the right shape. Obviously to make this work, it is necessary that the figure is a little smaller than its "hole" or would not fit. If the figure is a figure we say "radially symmetrical" there are no problems and I can reduce the solid to be inserted in scale, but if the figure becomes more complex (e.g. a s) and the redo in scale, it does not enter well in the hole but the boundaries begin to enter into conflict. so I would like to know if there is a method to "eat the edges", like to reduce the contour of the figure - example- 1mm from the edges so that the figure keeps its "skeleton", I don't know if I explained. In particular, the figures I have to produce are not s, and are not regular, and I do them with the spline tool for which also reduce them using the quotas on the various points is very complicated. Does anyone have any advice?

if you have to ask for clarifications on a specific software verify that there is the specific section: for the best known software there is solidworks. this because by opening a discussion in a generic section you may not involve users who can give you an answer.
said this the solution is to use the move face command with the offset option
