Removing CAD & adding a new CAD that has a different part#

[[Ga...]]

I have a new part that is slightly different then an existing program. All the same features except a few new ones at the end of the drawing. 2 different part numbers but from the same part family. I'd like to do a save as to the existing program, remove the CAD, add the new CAD and make changes to the program. Can I do that without creating issues? Otherwise I will be forced to create a new program with 1,500 features.

Thanks,
Gary

Nope I do this all the time.

Open the new model in a brand new program.
Load in your new model, and orientate it the right way
Create a base alignment that matches the existing program's alignment(Same features and any Special offsets or rotations)
Save the CAD model (not the program)

Save as your current program to it's new name.
In the new program, go to CAD>View>Delete
Then load in your new model

CAD> CAD File> CAD Model Comparision

Run the comparison, select all and apply - you might have to do that 2-3 times.

Change the Colours of the Model/Geometry so you never forget which version of the part you're working on.

WOW! That is impressive and I never would have thought of doing it that way.

Thanks,

If you have PCM you could even make the program parametric so 1 program could work for both parts... automatically switching the model and everything.

But, it's seriously debatable how often that's worth it vs just having 2 programs.

I have used the method Jeff referenced and the method Michael suggested above, and they both work as expected. I suggest using Michael's way only because when you get the solid model aligned before importing it, it eliminates the chance of features being moved accidentally, during transformation of the solid. And even using extreme care, it CAN happen.

Another point for my method is:

You are importing a .sab file created by Calypso into your finished program. This file is generally smaller and the CAD Evaluation works much better and faster than if you're working from a converted .step file.

The initial part of your process is sound and is definitely a time saver if you intend to reuse the model. This is my typical process when starting a new programing project. As soon as the CAD model has a defined coordinate system that I will be utilizing for my base alignment, I also communicate this to our CAD designers to modify future revisions. This way all imported models align properly. Same for secondary models such as assemblies or fixturing. Communication with your CAD designer can save you a significant amount of time.
