Autocad automatically extrudes lines arcs into surfaces ???!!!!!

[cekuhnen]

for what ever odd reason in a file Autocad extrudes everyline or arc I draw automatically into a surface.

here is a screenshot:

any idea what setting caused this?

Hi,

>> in a file Autocad extrudes everyline or arc I draw automatically

I guess the result is not a surface (the object type when you select such a line/arc/....

And I think it's the sysvar THICKNESS which should be 0.0 by default.

If I'm wrong please update a drawing, not a screenshot.

HTH, - alfred -

Do you have a closed polyline boundary?

What about using the Presspull command?

Polysolid might be another option.

Can you post small example file that exhibits this behavior (remove all extraneous geometry from the sample).

I am going to ask for a copy of the autocad file but it is not the width tool as this also happened with acrs and all surfaces that the line / arc created were vertical!

plus there is this UI change you see on my screenshot were there are vertical lines before I click showing the start end of the line as well as corner points of other drawing measurement elements.

Here is a screencast: this is NOT the width in deed

Attached is the autocad file - on every computer this file loads the tool acts the same way in the document.

I believe Alfred gave the correct answer in the first reply....  The drawing has an assigned THICKNESS of "6"

Regarding the vertical lines, that "may" have been addressed in a Service Pack.  Have you installed SP1 or SP2... or neither?

odd I am curious about how she did this by accident.
thank you for the information!

[jsanchezC6XDR]

very nice. never came across this until now. -THICKNESS- set to 0,0 confirms this variable exists!

thanks man!

CAD software mainly deals with solid objects. There is no solid object in the world that is zero thickness. For solid modeling concept, a line is a zero thickness thing. So, if you extrude it, it will be a surface (zero thickness surface) not solid. To make it solid, you must make a closed boundary and join them together by "join" command.
After that, use extrude command.
It must work.
