Making an assembly parametric sound

[belm]

Hi all,


I'm a studentrelatively familiar with Pro/E, however a recent assignment requires us to create an assembly that is entirely parametrically sound to the point where one dimension can be changed, and the entire assembly can be resized by 150%.


I know of family tables, skeleton models, and parametric relations, but I was wondering in your opinions what would be the best way to go about this. Is there any sort of or relationship that can be applied to each component of the assembly in order to achieve this? Or is it a case of having to add parametric equations (i.e. d1=d2, etc.) to every single component individually?


Thanks in advance.

You could probably do this by using ("design engine bart"s...) bounding box in a skeletonmodell that drives all the single parts geometry. The box could have a relation that makes the zize of the box to go bigger or smaller. then you just have to change one single value to update all your geometry...

Thanks for your reply Tobias.

Is the bounding box an add-on or is it an element of Pro/E as standard? I'm using WF4.

bounding box is a "modelling techique". not an add-on.

Murray,
this sounds like top down design. Create a skeleton and use publish/copy geom to drive your components. Then you can scale your skeleton and all components will follow accordingly.

Thanks for your help everyone. I've decided to use a skeleton, as well as making every individual component parametrically sound by using the relations editor as we get extra brownie points for considering further design intent.
