Attaching zone/hatch information to a block attribute automatically

christine_canavan — Mon, 04 Nov 2019 13:22:57 GMT

Hi!

I am quite new to autoCad so apologies if there is a simple solution.

I have created Blocks to use to export using attout or dataextraction for a schedule using block attributes. We have zones that are created using closed polylines and hatching, and it would fantastic to automatically assign the right zone number to a block, if it is placed in a particular zone.

At the moment, the zone information can only be put in manually, or just coordinate locations exported. I could also find some way of exporting the coordinates of the zone boundaries, and assign in excel after - but this seems more needlessly complex.

Thank you for any suggestions!

Hi,

>> it would fantastic to automatically assign the right

>> zone number to a block

What product are you working with? Plain AutoCAD does not have a function for that, Map3D (or Civil3D) have GIS-functions included, and using the topology functions from Map3D can find point-line objects (point, text, block) inside GIS-polygons.

I am using plain AutoCAD, however I am able to download MAP 3D with the package I have. Thank you! I will look into this. Do you have any advice regarding integrating into this software?

Hi,

You need first to use command _MAPCLEAN to make sure to have only one border between 2 zones (no double objects, crossings are handled as different objects, ...)

Then command _MAPTOPOCREATE to create a polygonal topology, based on your borders (most polylines) and your centroid objects (in your case I guess blocks).
