yes you are right..PTC copied parametric modelling from Inventor and solidworks..the backbone of history based modelling...
Oh let me see...
1. replace sketch entity..in solidworks 2014..oops..was there since long back in Creo
2.Model viewer introduced in solidworks 2012..oops so sorry again...long back in was there in Creo.
still can't make a cross section in solidworks which can be used in part and drawing both.
no option in solidworks to flatten a surface....
no toriodal blend..no spinal blend...oh they are only there in Creo.
just want to make one thing clear...i have no emotions for PTC the company..its just the software i Love.
