I attached the drawing with a sample block, if you would like to try.
Interestingly enough...using the STRETCH command on a normal rectangle does not produce the results you describe:
Yes, a line or rectangle behaves as you say ie click a line, grab the end grip, type 10, line increases in length by 10.
But, click on the stretch grip on my block, type 10, block resizes to 10 in that axis.
I am using the word axis as I have a stretch in the x axis and the y axis, but applies to any stretch command in any dynamic block as far as I can determine.
>>>> Expression: 2*12
stretches the box 24 units as expected
Specify second point or <use first point as displacement>: 'cal
>>>> Expression: (10+2)*3
results as expected
Can't enter a formula in a dynamic block stretch without the 'cal
Try my block, see what you think.
[quote}dynamic block with stretch function constrained to a(n) axis is how I am reading this[/quote]
Correct
