A couple of different options come to mind:
1) You could create a global variable in each of your parts/assemblies and call it "scale factor" And give it a value of 1.
(You can even use a single text file with that variable and link it to each part/assembly).
Then, for each and every dimension in every sketch and in every extrude and plane offset, etc... have the value be your originating value multiplied my "scale factor".
For some complex stuff this might not work, but for relatively simple geometry it should work.
Then, when you want to scale it up....change the "scale factor" number.
In my mind this works.....haven't actually tried it out.
2) At the end of each part, create a scale feature and scale it by a factor of 1.
Then link the scale factor to a global variable. Export it to a text file, then import that text file into every single part.
Then link it to each and every scale factor.
Then, when you want to scale it up, edit the text file and change the scale factor.
This would probably wreak havoc with assemblies, but maybe it would work. You would have to play with it.
3) Use a design table and basically do # 1, except drive the dimensions in the design table and multiply them there.
There is also this:
I like the sounds of #3. Do you know where I could look for an example of how to link all the parts to a design table?
Great Information Dan. I played with or used all of those in production.
Otis there are a couple more options as well.
4) Use a Skeleton Sketch(s) Part (SSP as it is known on the forums) to drive your assembly. Skeleton Sketch Part Method for Large Assemblies
5) If you don't mind buying an extra program DriveWorks will do the same thing as well plus more. Look them up if you are interested.
Whatever method you use, do yourself a favor as your design is progressing - modify a few dimensions and make sure your parts are moving and rebuilding properly.
Thanks for the warning. I am going to play in a pack and go sandbox.
Just don't throw sand, just pack it........
Might I ask John, where should we pack the sand! LOL!
DriveWorks might be another option if you want new parts/assems/drawings for each variation.
