SOME TIME HATCH WITH NO AREA ..WHY?

[adellll]

Sometime when you make list com. to hatch you find no area . especially when you make outline off plan , pls. I hope someone have solution for this problem , I ll grateful for anyone can help.

That's not an LISP issue - you can't see the area in the properties palette too. 

Unfortunately, the built-in getarea function can't handle some hatch's boundary issues as your 0-length segments. You can see that by restoring and exploding the boundary. BUT... paradoxly, usually you CAN get the area from the boundary curve itself.

I also wondered whether the two zero-length segments [coincident vertices] in the Polyline boundary are the cause, but for me, the Hatch pattern at upper right does list an Area, and it has the same two zero-length segments.

[And let's not confuse LIST as a command name and LISP as part of the name of a customization programming language.]

[adellll]

thanks for your reply , if (the two zero-length segments [coincident vertices] in the Polyline boundary) are the cause, is there any hatch lisp or any solution for this issue?

I must admit I have no idea what's going on. It's beyond the issues I usually have. Can't fix it to get the hatch area.  Besides, it tends to crash my ACAD.

@Kent1Cooper it could be that I have C3D as ACAD... something tells me that I've heard of this sort of issue before.

BTW This issue should be moved to the general autocad forum.

ERASE the one troublesome HATCH then rehatch, works fine now. Took less than a minute

The other two in the box work just fine here in R2023.1.4 for me (WIn10Pro, not MacOS).

It's already move , I think there is a solution somewhere , thank you for your time, have a nice day..

[adellll]

thanks for help , the hatch on the right I find area ok but the hatch on left its not work properly. I use win 10 and cad 2022. any way thanks .

I think the solution is reducing the number of virtx of pline to minimum.

Deleting the hatch and remaking it worked for me. 

Sometimes when I have this problem, I right-click to generate a boundary, and select that boundary to create a Solid hatch. That seems to work best. 

You can also join the boundary into one closed polyline and take the area from there. Or just use Measure.

To correct the Hatches without an area I did the following:

I selected one of the Hatches without an area

Right mouse clicked

On the cursor menu I selected Hatch Edit...

In the Hatch Edit window under Boundaries I clicked on Remove boundaries

I selected the boundary around the Hatch which will unhighlight

Then I right mouse clicked to bring up the cursor menu and selected Add Boundaries

I then reselect the boundary that I selected before and the boundary highlights again

I hit Enter & click OK to dismiss the Hatch Edit window.

I repeat the above steps on the other Hatch without an area and 

now both Hatches have areas (see attached dwg):

It seems it's moody. What didn't work yesterday works flawlessly now. Weird.
