so my problem comes I have a file that is file ext. Sldprt with all the dimensioning on it, when I try to save it as .Step the dimensions disappear.
what option do I select so it transfers the dims as well into the step file?
It is not possible. STEP files are dumb geometry only. STEP file format is not capable of storing dimensions. You get an accurate shape, but dimensions and features cannot be exported to STEP.
you would need the MBD add-in and to save into the step242 file format.
oh, and i think that only applies to dims created with the MBD add-in (i don't currently use MBD).
Josh and Jeremiah are correct. STEP only transfers the plain model without history / parametrics. To be precise: only a surface model is transfered, and the target system has to stitch a valid solid. It doesn´t matter, who is source and who is target system, this behaviour is caused in the definition of STEP file format. STEP 242 can contain PMI, which are cosmetic dims without driving the model. In SWX, the Model Based Definition toolset can create such PMI and save it to STEP 242.
