Hatch has no AREA??


Recommended Posts

How can it be that a hatch object has no area property?:x

 

Using the AREA command, it says the object has no area.

None shown in properties.

None listed using vlisp (vla-get-Area Obj).

 

I have seen this before, but could never figure out why or how it happens.

 

 

 

Any thoughts?

There's a loop in the outer boundary halfway down the right hand side. If you move your hatch and the cyan line crossing the road and then get rid of the loop in the boundary you can create the hatch again and it does have an area this time. I'm not sure if it was the loop or the cyan line that was causing the problem.

rkmcswain gave the clue and I just followed it up. I didn't know about the problem caused when the boundary intersects itself, thanks for that rkms :thumbsup:

I think I ran across that one time - something like this:

That could be two separate hatches, or in this case a single object was selected, which is the polyline that crosses itself. An exaggerated example of course....
