counting different geometries as blocks

[dani-perez]

Hello all,

I received a DWG scanned in PDF. It has many layouts and I have to count different elements: bulbs, bathtubs...if I explode the PDF, all elements are broken down into lines, circles, arcs (no blocks), and all of them, in the same layer.

Is there a way (or a LISP) to select a pattern of basic elements (lines, circles...) that form a block, then, select an area of the viewport, and receive the number of exact matches of the pattern (a kind of pattern filter)?

Thanks all.

If you have access to Bricscad they have a command called "Blockify" that you could use.

have you tried pdf import.

Hello,

No, I do not have access to Briscad

Hello,

Yes, but unsuccessfully

I think there is an alternative to the Bricscad solution I can not remember who, I have a suspicion will try to find. 

If the BLOCK object has an outer shape like a circle then may be able to do some real rough counting by using approx radius. 

Post a dwg with the objects so we can see what your trying to convert/count.

Try to search the board for "blockify". I know that @marko_ribar has his own routine for this purpose, you should be able to find it.

EDIT:

Just realized that the new COUNT feature actually CAN count geometry from exploded blocks (or just same/similar/rotated/scaled as some existing block). They are identified as "errors". I did just a quick test - did not find a way to "fix the errors" by "blockifing" them.
