Difference Between "Point" and "Base Point" In Parameters?

What's the difference between the "Point" Parameter and the "Base Point" Parameter in the Block Authoring Parameter Pallet?

Basepoint is used to specify a Point in the Block that will be used as the Insertion Point. Much as you can create a Block using WBLOCK and assign an Insertion Point, BASEPOINT is used in this way.

The POINT Parameter is nothing more than a place to generally attach Actions to. There are several Actions that can be assigned to a Point Parameter. MOVE and STRETCH roll off the Keyboard but there are other uses for this versatile Parameter.

One use that may elude some Dynamic Block enthusiasts has to do with Insertion Points. (This could be where some could get confused with the Basepoint Parameter, which as it states is the Basepoint, and is always.) Point Parameters can be added to a Dynamic block to give the illusion of multiple insertion points. Using CTRL on the Keyboard when inserting a Dynamic Block with Multiple Point Parameters will give the user the option to insert a Block from multiple positions. These do not override the Basepoint Parameter but rather complement it.

Thanks, Charles. That explains some problems I've been having with Dynamic Blocks.

Hi,

I am having some difficulty with a block I created, and I thought maybe you all could help. I've created a block used to lay out Cable Tray for IT drawings. I've put in the required stretch actions to dynamically change the width, but the insertion point is messed up. When I try to fix it the block elements go "wonky". I would like to have different insertion points for each "width2" linear parameter. Is this possible? Please see the attached file. Any help would be greatly appreciated.

hi!

 

You can insert basepoint parameter where You need block insertion point and moving it with Your linear parameter where You need

That's great! I wonder why it didn't work for me. Oh well. Thanks!

Can I use point to keep my attribute text in consistent placement when using a dynamic block in multiple locations? That is what I am looking for currently. A way to have my attribute text 'snap' to preset points on the block
