Block on line

[sanjaymann]

Hi,

I have two layers. one layer has polylines and the others have BlockReference. I need to get blocks which intersect the line.

currently I am looping lines ane by one and then I am looping all the blocks and check which all blocks intersect the line .

BlockReference.IntersectWith(br, Intersect.OnBothOperands, ptCol, IntPtr.Zero, IntPtr.Zero)

but this takes a hell lot of time becasuse I take one line then loop all the blocks to check intersection and then another and then another. Its killing.

Can anyone guide me with a faster approach.

Hi,

Just an idea, why not to use a selection filtering by block references in fence mode using the polylines coordinates as the fence, this should work with straight segments only polylines, but may require aditional work with bulges.
