# Dynamic Block Help!

Can someone help me with this dynamic block...when I stretch it the arrows do weird things.

It would be nice to stretch with the arrows not losing their shape.

Any thoughts. I've attached the file if someone can assist on making it work right and forwarding it back.

That would be very much appreciated!

Thanks!

I do not believe that you will be able to get the Arrows to rotate with the change in the Radius of the Arc.

I don't understand why they can't stretch in place.

Maybe it is because of the angle of the arc?

Other suggestions on how I can achieve this same symbol look and get it to work?

The angle changes on the arc the more you stretch it, for the arrows to stay aligned it would require that they be rotated in accordance, this could be done with a move and rotation parameter combined with a Block property tablet and some mathematics.

Not something I can throw my mind into right now and I wouldn't be able to guarantee success either, your gonna have to prioritize, will this save you enough time to make up for the amount of time spent making this right?

Give Kudos where credit is due, Mark "accepted as solution" if the post solved your question.

Hi, please see attached file for a possible solution.

Since Autocad 2010, most of previous dynamic issues can be solved by combining parametrics with dynamic actions.

I changed a few little things in the bloc you posted and it is now functionnal, please see attached file. Note that there is a doted line on Deftpoints for guidance in the bloc: this line will not print.

...unless you have access to a version of AutoCAD that allows Geometric Constraints to be used.

LT Versions do not have this functionality.

Hi Charles,

I know this fact. However, the original post did not request any version nor did it specify an LT version.

That was to let others who may come across this post know a limitation and to update my original response that this could not be achieved.

You showed the OP a way to do what he requested.

Thanks so much for shooting back a 'fixed' version of the dynamic block.

Unfortunately, we're working on CAD 2007 and I can't open it or convert it with TrueView.

Do you mind saving it down and reposting?

Much appreciated!
