I am obviously missing something simple and basic. I am putting this question in the simplest way I can
think of so the principal can be established without making things too difficult.
I can sketch a rectangle, constrain it and pad it to a particular thickness.
I am not wanting to encounter TNP further down the line so I don't want to define a datum plane on the top surface of the
padded solid.
I have tried to define a datum plane by selecting three vertices first but the option to do so does not seem to be in the list.
Could some kind soul give me the steps I need to define the new datum plane without attaching it to the padded geometry
please?
I thought maybe I could do a sketch on the XY plane and then offset it but that might my model no longer parametric.
This may be a silly question but the examples book I was using simply defined the new datum plane on top of the padded geometry which could expose one to the risk of TNP further down the line.
Thanks in advance
