Measuring area by point - After Enter it continues to ask for another point...

[CE1]

I can't figure out why my area measurement tool won't give me the area when I try to measure with point. It should give me the are after I put my points and click enter. But when I click enter, it keeps telling me to specify next point or [arc,length,undo]... How do I fix this?

Thanks.

After the AREA command, you have to type in _OB then click on the boundary of the area, not inside it...

I know measuring the area by object, but I want to do it by point, because I want to measure an area that doesn't have polylines.

Drag&drop this humble small lisp in your modelspace, then run it with arealabel

Is there another way you can send me the link or "lisp" I haven't figured out what that is yet

Stop. AutoCAD will continue to keep asking for points until YOU stop picking them. That's the way it works. Pick your last point then hit the Enter key.

That's the problem, I pick the point and click enter and it just keeps asking me for the next point. It doesn't stop.

I'm using 2012 at the moment and it does stop. Not sure why you would be seeing something different. I'll have to check out how it works in 2013.

 

I'll be back.

 

Test completed. No difference in 2013.

I was wondering, maybe it's like a setting or something that's causing the problem. I don't know. It should work like the way described it.

[ReMark]

You could use the BOUNDARY command to create a boundary (one polyline) then use the AREA command with the OBJECT option.

 

If there is a "setting" then it is one I do not recall at the moment. I'll have to think on it and get back to you unless somebody else beats me to it like rkent or nestly.

Do you get the same results if you use the MEASUREGEOM command with ARea option?

[CE1]

ReMark,

 

Yes, It gives me the same result. I click enter on the keyboard and I tried right click and clicking on enter.

Both commands work as expected in 2013.

 

Is the difference attributable to the fact that you are using a vertical product?

[CE1]

I am sure it works and that's why I think I need to make a change on something and I don't know what it is. I am just making a simple conceptual site layout. Nothing 3D or anything. I am in the Civil 3D workspace.

How are you starting the command?

What does the command line say before you start picking?

What does the command line say after you have picked the first point?

[CE1]

So I just opened a completely new file with nothing in it and the command works fine. So what is wrong with the file I am using? My file is corrupted somehow. Sometimes it doesn't save and I have to audit and then save it again. I don't know why it starts having problems all of a sudden...

Copy&paste the following code in Notepad, then save the file as AREALABEL.LSP

 

(defun c:AREALABEL (/ ar textht p1)

(alert " CADTUTOR.NET 2012 \n\n Powered by: emigrato@wp.pl  ")

(initget 7)

(setq textht (getreal "\nEnter text height: "))  

(setq p1 (getpoint "\nPick point inside area to label: "))

(while (and p1)

(command "_bpoly" p1 "")     

(command "_area" "_o" "_l")     

(command "_erase" "_l" "")     

(setq ar (rtos (getvar "AREA") 2 2))     

(command "_text" "_m" p1 textht "0" (strcat "Area: " ar " m\\U+00B2"))     

(setq p1 (getpoint "\nPick point inside area to label: "))     )   

(princ)   

)

Thanks for the codes Emigrato.

 

I just copied everything I have in the file and paste it in a new file. Area command now works fine. I just don't understand how things go wrong in these files sometimes. If I had a more complex file I wouldn't be able to copy/paste. The audit command doesn't seem to correct everything.

Did you do a command line purge of the drawing first?

[CE1]

No I didn't. I thought that command deleted all the unused layers.
