Dynamic Block "Midpoint Snap"

[ScottyG]

I'm new to working with dynamic blocks, using AutoCAD 2007. I have a base cabinet elevation block and want to have it so that when I change the height the door swing line stays at the midpoint of the door. Any ideas?

I assume you are using a linear parameter and the stretch action. If you exclude the item you want to stay in the middle from the stretch action you can then assign a second stretch action to the same linear parameter i.e you can have 2 stretch actions assigned to 1 linear parameter. If you then select the the second stretch action and look at its properties you will see an 'Overrides section'. Change the distance multiplier to 50% and the item you wanted to stay in the middle will only move 50%.

 

I hope you got that but if you didn't re-post and I'll attach a simple file showing it.

Thanks Bob,

You were correct in assuming that I am using a linear parameter with a stretch action. What I want is a typical base cabinet with one door that has a toekick. The toekick needs to be separately adjustable from the door/box height and I think that's where the problem lies. Maybe I'll need to draw the toekick separately. Next I'll attempt to make a 1 door/ 1 drawer base block. Wish me luck.

If you want to upload a small file showing what you want to do and bit more information I'll have a look at it for you.

You may need to upgrade, this is possible with the use of constraints. Not sure of a way with AutoCAD 2007, a small file would help.

Here you go. It's a pretty simple cabinet so it's frustrating that I can't even make this dumb box dynamic.

Does this do what you wanted? Note that I removed the flip option and replaced it with a viability state. I find it easier to work with than flip. just draw both options and select which you what to see.

Could you save as 2007.dwg please?

Here, I saved as 2007.

Works like a charm. I see how you associated that stretch with the swing line at the middle of the door, brilliant.
