In all previous versions of SW we were always asked the question in the installation "Do you want to make drawing changes that will effect the model? Yes or No" (Or something to that effect). I always answered "Yes". Well due to everyone answering "Yes" (or at least 98% of them) to the question (According to Performace logs) SW took out this option in the installation. I wasn't aware of it until yesterday when I asked how do you change this. With SW help, we did find a way to change it. before we had to uninstall and reinstall to change this option, now you can change it via the registry.
Start\Run\regedit - HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\SolidWorks 2004\General - "Disable model changes from drawings"
and or
Start\Run\regedit - HKEY_CURRENT_USER\SOFTWARE\SolidWorks\SolidWorks 2004\General - "Disable model changes from drawings"
If you want this option to be able to change the model you need it to = 0
If you don't want the dimensions in a the drawing to update the model the answer needs to be = 1
To change the option Double click "Disable model changes from drawings" and enter the number you desire in the data box.
