Stretch Pair/Stretch Different Objects in Different Directions Using Same Value

[Anonymous]

 Good day All,

Kindly refer to the blocks attached, which consist of a rack profile and its various parameter sets. 

I have a stretch parameter set that adjusts the width of the frame on the right outwards. I would like for the left frame to stretch equally in the opposite direction. 

Question 1: Dynamic Rack.dwg
I tried to use two stretch parameter sets, namely Frame Width and Frame Width_, where 
Frame Width requires an input value, and Frame Width_ = Frame Width, however it appears that you can only use formula based expressions when working with constraints? I also failed to have constraint dimensions integrate with parametric sets via formula expressions? Are these assumptions true?

Question 2:
I read in a 10+ year old post that parameter sets are unreliable and that manually setting the parameters and actions was more reliable. Is this still the case?

Question 3: Dynamic Rack_Stretch Pair.dwg

I tried to use a stretch pair parameter set to stretch both, by setting the second stretch action of the pair's direction to 180degrees, but this didn't seem to work?

Question 4:
I exploded the nested blocks so that I could assign the geometry parameters which could be accessed in the host drawing. I would rather maintain the nested blocks as its more organised and compressed. Is there a way to achieve this? With a function similar to Revit's shared/instance parameters?

Question 5:
You'll see that if you lengthen the Frame CTC parameter that the hatch doesn't follow. How would I solve this? Would I constrain the hatch to the edges of the geometry being stretched?

Any guidance would be highly appreciated.

Regards,

Connor

Hi All,

I am currently trying to make a IPS setup with dynamic input.

Currently having issues making the middle panel grow left to right, similar thing with the right hand panel.

The left hand panel is fine, increase and decreases.

All i want to do is make the panel grow accordingly with in the o/a area but with the ability to have each panel bespoke.

Any help would most appreciated.

Thanks,

Curtis
