Dear all,

I need your help.
I want to develop a standard library of blocks in autocad 2008. I want to make it a Parametric type for multiple sizes of same object.
For example my block is a Simple bearing block. I want it for shaft diameter ranging from 20 mm to 80 mm. Then centre height, over all width, length and height of bearing block, mounting distance, mountng holes etc. I want to make parametric. i.e. I select the shaft dia and I can insert a block with desired dimensions.
I do not want to use dynamic block command as it's stretch, scale command will be a bit complecated for other complecate objects in my library.

Please suggest a suitable method.


Thanks in anticipation.

Samir.
