dynamic block distance lisp adjustment

sadefa — Thu, 29 Sep 2022 08:32:44 GMT

Hello to all.

I am complete lame about lisp programing. I need some help for automation of process I do manually and it’s driving me crazy.

I have a dynamic block, which has multiple custom properties – distances, which can be adjusted. Two of them are to adjust the distance from already present marks. The present marks are placed every 5 meters. The first one starts at 0 coordinate on X axis, so that they are placed on 0, 5, 10, 15, etc.

What I am looking for is a way to select multiple blocks and ask them to adjust the distances so that they end at the already known marks.

Thanks in advance.

Don't follow. Elaborate. And post some bigger picture to see what and how should be automated. What is the initial state and what the result.

That's not true in your sample drawing. The X coordinates are things like 516740.728 and 516757.561. [Why so far from the origin?] If they really were at whole multiples of 5 in the X direction, maybe something could be worked out that would round the Distance1 and Distance2 settings relative to a Block's insertion point, to put their ends at the closest multiple of 5, and all the User would need to do is select a Block. As it is, it would at least be necessary to select not only the Block but also one of the vertical grid lines. [Why those are Polylines, I can't imagine.]

Also, are the numbers in the Attributes supposed to be changed accordingly? To whole numbers only? Should the position of a Block be forced to where those are whole-number distances? Etc., etc.
