Simple dynamic block behaves differently depending on which grip is adjusted first

[mike_eddy1]

This is the first dynamic block I've created and it behaves *almost* exactly the way I want it to.
I'm hoping you experts can help me with 2 issues: (1) grip behavior and (2) convert individual block line/arc elements into a single polyline.

ISSUE 1: GRIP BEHAVIOR
The desired behavior is for the block height to always align with the "Height" grip and the block width to always align with the "Width" grip.

• TestA: The block behaves correctly if I make any adjustment at all to the "Width" grip before I make an adjustment to the "Height" grip.
• TestB: The block behaves incorrectly if I adjust the "Height" grip before I adjust the "Width" grip - this results in the block height and width no longer aligning with the grips.

ISSUE 2: CONVERT TO POLYLINE
I would like to apply a linetype to the block with Linetype Generation enabled, but right now the block is composed of individual line/arc elements rather than a single polyline. When I try to recreate the block using a polyline rather than individual line/arc elements, it behaves even more poorly than in the examples above. Can anyone see a reason why this block cannot be composed of a polyline?

@mike_eddy1,

Try this please:

• Edit the block with Block Editor
• Select the Height Linear Parameter
• Chain Actions = Yes
• Number of Grips = 1

Save and Close the Block Editor.

Test.

Let us know if that works for you.

Regards,

Jerry

Thanks for looking into this, JBerns. I still encounter the same scaling issue even when I make those changes. Did this fix the behavior for you, though?

[mike_eddy1 · Accepted solution]

I found a solution. Instead of using a combination of a Linear Parameter and Stretch Action for the "Vertical" grip, I should have been using a Vertical Constraint. Now that I've made this swap, the block is behaving correctly and I was able to use a polyline rather than individual line/arc elements.

Glad you found a better solution, Mike.

On the off chance someone runs across my post and needs my revised block, I'm attaching it here.

This block ALMOST meets my needs perfectly, except I cannot apply a Rotation Parameter and Rotate Action to the block, maybe because I have too many Geometric Constraints in place?

If anyone can help me to make use of the Rotation grip in this block I would greatly appreciate it!
