Changing tolerances when importing a step file

[chrischin42]

When I receive a step file from a customer all the dimensions are nominal. Does anyone know of an easy way to adjust certain dimensions up or down so that all dimensions are in the middle of the tolerance? For example I would have to shift the geometry of the 5.000 bore up .0025" and the 5.200 bore up .005". I currently do this with the translate feature but I have to reconnect all the other geometry to it. This is a somewhat error prone procedure.

Thanks for any help,

What are you using to drive your tooling? Do you use the solid edge or create a turn profile and drive off wireframe?

I generally leave the models alone and manipulate the wireframe once I have created a turn profile. An example of this would be threads.

Generally they are drawn and dimensioned to the nominal. I then create wireframe that puts me at the mid point of the thread tolerance.

We create a turn profile and delete the solid.

I would use model prep changing the solid to the nominal dimensions and then only use the solid. Why delete the easiest tool to use in lathe which is the solid? Still need wireframe from time to time no doubt, but nice having the wireframe from a solid show up without having to make it.
