Dynamic Blocks - Maximum and minimum stretch points

[Warrick 123]

I'm trying to create a dynamic block that stretches between a minimum and maximum height. The block I'm trying to create is an "Acrow Prop" which has a height that ranges between 1050-1830mm. Is there any way to set a function that will stop stretching out side of these figures?

 

I'm currently using AutoCad Mechanical 2013

yes. Click on your distance parameter and look on your properties palette. In the "Value Set" you can specify a maximum and minimum size for your parameter. If you leave distance type as "none" you can strectch your parameter to any distance or you can set an incremental value if you want to limit it to (say) 10mm steps. Finally you set up a list of possible values, say 1050, 1250, 1400 & 1830.
