Densities in Configurations
Densities in Configurations
(OP)
Can anybody help me to create configuration specific densities?
Would appreciate any assistance anyone could give. I am using 2003.

RE: Densities in Configurations
But my gut tells me you're gonna need more than this.
What are you going to do with these densities?
Tell me more about why you need this and I'll take another stab at it.
RE: Densities in Configurations
I tried the string you suggested in a design table but this did not have the desired effect. The design table just lists the material names as configs and the next column was the string you suggested with the appropriate material density next to the config name.
Anything else I can try?
RE: Densities in Configurations
Go ahead and post your e-mail.
In the meantime, I'll come up with an example to send you.

All I need is your e-mail and I'll gladly send it.
RE: Densities in Configurations
Can you tell me how?

Thanks
RE: Densities in Configurations
I am interested too.

That's really a way to avoid the limitation. But you are masking the real mass properties of the configs (which remain equal). So I think there are some issues for more complex applications:
- the rest of the mass properties (moments of inertia )are inconsistent with the given information on the drawing
- usisng the part in assemblies, the mass properties of the assemblies are inconsistent (specially for moments of inertia and center of gravity).
Do you agree?
I think the best way is still having different files for different densities.
RE: Densities in Configurations
Do you think its worth requesting the ability to control mass property info in configurations as an enhancement?
By the way TateJ's method got me around what I was needing to do - thanks.
RE: Densities in Configurations
The absolute best way would be to use different files for different densities.
Have either of you played around with envelopes?
I'm just thinking of another idea I'd like to try.
I'll get back to you...
RE: Densities in Configurations
I have it.
Who wants it?
RE: Densities in Configurations
Now I have the absolute best solution.
Step 1. Create a PART1 to control the physical size of the part.
Step 2. Start a new part & insert a BASE PART (this would be PART1).
Repeat this for each material you need.
The changes you make to the physical parrameters of PART1 are automatically reflected in all the other parts!
All the other parts can control the material properties.

Step 2. Start a new part - STEEL.SLDPRT. Then INSERT BASE PART, and select SIZE.SLDPRT.
Step 3. Set up your MATERIAL PROPERTIES for STEEL.SLDPRT.
Step 4. Repeat Steps 2 & 3; but this time make ALUMINUM.SLDPRT.
Now you can make any "physical" changes to SIZE.SLDPRT, and see them reflected in STEEL.SLDPRT & ALUMINUM.SLDPRT.
I haven't tried making changes to the "material" parts - just to see what happens - but, I'm thinking you could pretty much do whatever you want to them. Just be aware that changes to the BASE PART will affec all the "material" parts created downstream.
If this don't clear it up for you, then post your e-mail address and I'll send you an example.
RE: Densities in Configurations
That's a nice idea TateJ. But I think we can improve it. Why 3 parts? You can have as much parts as different materials: in this case only 2 are needed. Just choose one to be the Base Part (the one that control the dimensions), lets say the steel part. The Alu part just controls the different density (when editing the dimentions in the Alu part you are changing the steel part also, and vice-versa). I think, until now, that this is the best solution.
RE: Densities in Configurations
And, sure you can have all the parts you want.
I only did 1 base & 2 material parts for the sake of an example.
I have an example I can e-mail.
RE: Densities in Configurations
Can you send me the example file for the same?
