Dynamic Block circle stretch

[ROBP]

I have a block with visibility option but i need to be able to stretch one of the inner circle to match a few fixed dimensions i am sure it can be done with a lookup table but after a few trial and error i don't seem to be able to achieve it.

 

Offset is an option i can probably add in the authoring palette by copying a command and changing the action related to it but will it work , if it does i am still back to square one i need to set values for that circle and be able to choose it so that the circle will follow the preset dimensions, can anyone of you help?

 

Best,

 

R

 

P.S. file can be sent to be able to see the flavor and test it

Try using scale, and if you intend using odd sizes I would suggest using a starting circle of 1 or 10 or 100 units, just to make the other values easier to work out.

For some unknown reason it does not work i must be doing something wrong dang

 

Reminder the values are fixed ones (pipe wall thicknesses) and it must have a lookup for me to choose from from a drop down menu.

Maybe i should send the file for review at least get one started and i will add the rest?

This is just the 2 circles, the two linear parameters are linked to keep the wall thickness constant. Post the block you are working on if you have any problems
