how can i control a model's dimensions by volume?? 1

[threadkilla]

i need to make a 250 ml volume part and i want to be able to adjust dimensions but not change volume??

Threadkilla,

You will need Behavioral Modeling (BMX). Follow these steps:

1) Create an analysis feature to measure the volume
2) Create a relation analysis feature to calculate the error of the measured value and the desired value. Example: error = abs(volume:FID_analysis1 – 250)
3) Create an optimization feature that will minimize the error by adjusting the desired design variables (dimensions)

More information on BMX is available in the FAQ Behavioral Modeling Extension (faq554-784).

The solution posted above is overkill for problems where the volume can be calculated in closed form. For example, if a rectangular prism has dimensions d1, d2, and d3, then volume = (d1*d2*d3). A relation can be created that will allow for one dimension to be determined knowing the other two. You can even do this for each dimension individually using Pro/PROGRAM.
