Dynamic block - how to keep objects in middle when stretching

[jrn]

I want to make a simple dynamic block showing a plan section of a window with one mullion between the window jambs.

I've succeded making the block stretchable to any given length that is required.

 

The problem is, that I can't figure out how to keep the mullion right in the middle between the jambs.

 

Is there any simple way to get there using the actions and parameters in the block authoring palettes?

 

Please help.

Thanks

You should be able to use = constraints.

 

Can you post the block?

SLW has given you a way without using dynamic block properties but if you do want to use them add a second stretch action for your middle bits and change the action multiplier (use properties palette) to 0,5.

Thanks.

 

any simple way will make me happy ;-)

 

Heres the block

thank you!

Excelent and quick help:)

I made it work with the action multiplier set to 0.5

 

(I'm still a bit lost with the constraints-thing...)
