Advanced Dynamic Block Question

I have came to the conclusion that creating Dynamic blocks for the most part are easy. now I need to push it to the next step.

this might be both Lisp and Dynamic block

it is easy to create a dynamic block that you can stretch to set measurements but, I need to create a dynamic block that can stretch along an arc.

it has to let me select the arc, line or poly line to determine the radios.

anyone know?

here is a example picture:

Any coding experience?

If you want help, you are going to have to post the block in the picture or some kind of DWG example.

i attached an example drawing.

the top block is the original block i created that stretches in length

i need it to be able to automaticly determin the curve and then stretch alonf the curve.

no coding experience. self tought by help menu on cad r9 in 1996. i can customize everything and do advanced drawings and trouble shouting but no coding and am starting to learn lisp. i would like to learn tho.

does noone know how to do this?

I'll take a swing at it. I'll get back to you soon:)

Hmmm. Not sure if this can be done with the dynamic block system of 2007. What you are trying to do is rotate an item around a variable center point. The center changes as the arc is bent. I dont think 2007 is capable of that. However there is a constraint system added to the dynamic blocks in 2010. using that you may be able to define the variable center point in relation to the bending arc. I haven't tried it as I am short on time today, but it seems theoretcally possible.

Maybe somebody can modify this. I think it would be harder to get a arc in there so I went with a dimension

I know I can get this to work it just requires time. Hopefully I can get back to this today and finish it

Let me know if this is what you are looking for. I'm not done with the block but I don't want to do more if its wrong. I know what people are going to say. "Why visibility instead of doing the math?" Answer: I got lazy!!

The problem with the way I have it set up is you can't set the top arc to any ol'curve. I went by what you have shown in the image above. If I do the math I can probably get it to align with any curve but wont get done today. Not enough time

is this for brick arches?
