How to find overlapping doubles ?

Angayo — Mon, 14 Aug 2017 08:01:19 GMT

Autocad has a habit of sometimes creating doubles of objects. If these objects overlap with the original objects they are hard to find. If these objects are scheduled, then the schedule is wrong. How can one easily find those doubles ?

I am particularly interested in spaces. Is there a way to find overlapping spaces of a particular style or on a particular layer ?

Hi,

overlapping items in AutoCAD can be controlled or treat with by OVERKILL command. >> Click << also by setting Selection Cycling ON you will find and removes duplicate or overlapping objects. >> Selectioncycling <<

Hi,

>> Autocad has a habit of sometimes creating doubles of objects

Which commands are you referring to?

I never had issues with AutoCAD that AutoCAD creates doubled objects, in most cases it's the user starting commands which by default create copies or doubles.

AutoCAD itself does not create double lines when you draw just one line 😉

>> Is there a way to find overlapping spaces

Can you please let us know what you mean by "overlapping spaces"? Please upload a dwg file that describes such a situation.

It could also be helpful to know which version and type of AutoCAD you are using, e.g. Map3D and Civil3D has a command _MAPCLEAN which can do a lot more with double objects compared to the standard AutoCAD command _OVERKILL.

Thank you for the advice.

I have Autocad Architecture 2016 and it does not know _MAPCLEAN.

About overkill :

It does does find not objects, but deletes them.
It is unreliable. Based on superficial testing I don’t understand why it deletes some objects and not others. The test objects are spaces with assigned property sets. Maybe that is why it doesn’t work.

So what will happen if I use it is that it will delete object it should have kept and and keep others it should have deleted.

About selectioncycling :

That would require to painstakingly go over all objects that might have duplicates.

@ Alfred :

I was not referring to any command. Merging spaces is a command that sometimes produces duplicates and obviously copy as well.

With spaces I mean objects created with the SPACEADD command. Two spaces overlap if their intersection is larger than 0. If Autocad could show me those, I could delete the superfluous ones myself.

Hi,

command _OVERKILL only supports AutoCAD entities, not objects from any verticals like your "AEC_SPACE" objects.

I would recommend to ask in the AutoCAD Architecture forum for how to identify double or overlapping AEC_SPACE objects.
