Dynamic Blocks sometimes work

[ktnalive]

To whom it may concern,

I can get dynamic blocks to sometimes work while other times they refuse to. Once I was here with a clock issue where the hands refused to rotate under the Lookup parameter, and after much discussion, I found that the block in AutoCAD LT was not created. So I recreated it and for some reason, it worked after going back into Block Edit. Now, after creating a block of a wrench, I am running into the same issue. Here I need to stretch the metric wrench and make it smaller. The wrench stays the same size after going through Block Edit. I have tried recreating the wrench into a block several times before going into block edit. It still does not work. I even deleted the file and started over, yet, it still does not work.

Here are the parameters used - XY Parameter, then in Action - Stretch, I then used the Lookup parameter, double clicked the Lookup, added the correct properties in the Lookup Table, clicked OK, closed the Block Editor, and tried the Lookup parameters only to find it did not work.

Note: I am in online schooling and my instructors do not even understand my issue... 😞

Please find my attached issue.

The Stretch1 action is associated with the Base Point of the XY parameter.  When a lookup changes the value of a parameter the Base Point position is always unchanged and the End Point value is what is changed.  Because of this, the lookup changes the values of the end point(s) of the XY parameter, but there are not any actions associated, so nothing appears to happen.  

Delete the XY parameter and remake it (or use a linear parameter which in this case would seem to make more sense) while paying attention to where you place the Base Point (first point selected) and the end point (second point selected).  Also pay attention when adding the action and associate it with the appropriate parameter point.

Here's your block back.  A couple other issues with your prior version were that the stretch window was so small it was not surrounding anything and you had an inappropriate selection set for actually stretching the wrench.
