Global rescaling of a part?
Global rescaling of a part?
(OP)
So far I have come across 2 suggested ways to re-scale a part; use insert > molds > scale or insert > features > scale.
But both of these are greyed out for me, so how do I do it? I have attached the file I would like to scale
It seems like a basic CAD function to me but obviously SW thinks different.

You can not scale a sketch.

So if I have a fully dimensioned sketch & have one 'master' dimension, all I need to do is change that 1 dimension?
Also if the sketch were extruded for instance, then it would be possible to scale it?
RE: Global rescaling of a part?
That depends on the type of extrude and how it is based on the sketch, but in general, yes.
Is there a reason you want to use the Scale function. (shrinkage, plating, etc). There may be better methods to achieve what you are trying to do.

My experience with 3D printers is not so much one of shrinkage but of "dimensional differences", i.e., some feature edges come out fat and some come out skinny. This is partly a function of the STL file since it is making faceted surfaces out of your smooth model, but it is more a function of the resolution/pixilation of the printing process. I have also found that the resolution of most 3D printers is different in the vertical (Z) direction from the horizontal (X-Y) direction. This is usually stated somewhere in the printer specs. This is not a scaling issue as almost all 3D printers do an accurate job printing to scale, though their precision is affected by the particular situation.
Have you 3D printed a scale test part such as a 25mm hollowed cube, or better yet an octagonal polyhedron? This will tell you a lot about what you can get from the printer in all directions. If you are sending your stuff to a 3D service bureau then they should be a key part of your conversation regarding what to expect from the printer.

If you go this route, there may be some trial and error to have a good dimensional part.
