Point parameters not moving after block table choice

WesFra — Thu, 30 Jun 2022 14:38:18 GMT

Hi all, and thanks for reading in advance.

I have a dynamic block that changes based on a blocktable.

However the 4 point parameters arn't updating their coördinates

see below, (left) first option and (right) another option.

I did gave them coördinates, so I don't know whats going on

update: I wrote them away and reinserted the block, but no change

@WesFra,

I think you may need a stretch action, but I'm not certain.

The Dynamic Block expert, @Libbya , will likely be able to assist.

By the way, there is a dedicated forum just for AutoCAD Dynamic Block assistance.

Why do you want those points in the first place?

Using them to move the "linework" around is a bit of bad practice in that you can move them anywhere even "a million miles" from the basepoint of the block which would totally mess up your drawing.

I'd just remove them and use an intersection snap on the two lines in the circles if I wanted to move the linework around.

The basepoint is moving along with everything else, I don't really see a problem in messing anything up.

Using move with an intersection snap isn't really the workflow I'm going for here.
thanks for the feedback though

Thanks, I'm looking into it

But your basepoint isn't moving with the block, it's staying at 0,0 (see the first two images below). And then if you change the state using the block table it breaks the block even more (see the third image).

I noticed that after I posted the block but I already updated it?
Or thought I did, it's moving along fine here, check the latest block

When a block properties table changes the position of a point parameter, any actions associated with that point parameter are activated for the change in position. You have 4 point parameters and each of them move EVERYTHING in the block, including the other point parameters! The four move actions combine to cancel each other out.

Here's probably the easiest way to get it all working the way you want. See screencast:

Wow did not know about the fact it also activates the associated actions as well, that's some deeper knowledge.
So you use the new points to balance it and knudge them in the right directions. I'll try and recreate it

Thanks alot, really appreciate the help, this keeps me moving forward in understanding dynamic blocks.

I probably also could have set new points per visibility, but that would've been 4x8=32 points.
But the less the better that's why I tried this approach. Thanks for dotting the i's
