Polyline and blocks

[Anonymous]

How to get blocks name and points where it is crosses with polyline ?

Hi,

Are you using COM or .NET API?

You would need to go into the block, iterate through its content and try to do intersection between each object and the polyline outside the block.

You would need to transform the entities according to the transformation matrix of the block reference before doing the intersections.

You could also use Explode in .NET that would give back all the block content at the right place - i.e you don't have to transform the entities yourself.

I hope this helps.

I'm using VBA. I try to made something like that:

1) find every polyline

2) for every polyline get them coordinates

3) made selectbypolygon for points from polyline

4) for every blocks crosses with selection made them name or id  array 

But I have problem to find blocks whom crosses selection.
