AutoCutter Posted November 18, 2010 Share Posted November 18, 2010 Hi guys, I have the problem that autocad extrudes the polylines I create automatically. for example if I draw (with the polyline tool) a triangle in the front view. it seems to be a 2d polyline, but when I change to the top view I can actually see that it's extruded into the z space 5 centimeters??? is this the normal behaviour of autocad, when drawing a 2d polyline, or do I have a weird option activated. I know this is a very basic questions, but I started using it 2 days ago... thx for ur help! Quote Link to comment Share on other sites More sharing options...
dbroada Posted November 18, 2010 Share Posted November 18, 2010 I haven't seen that happen before. Do you have a THICKNESS or ELEVATION value set? Quote Link to comment Share on other sites More sharing options...
AutoCutter Posted November 18, 2010 Author Share Posted November 18, 2010 no I don't. but I have the feeling that there's something like ELEVATION or EXTRUSION which is applied to the shapes. the extrusion is always 5 centimeter. here's a screenshot of a triangle I've drawn. -> nothing added afterwards. I closed the polyline by pressing the "c" key! Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 Type the word THICKNESS at the command line. Press ENTER. What is the default value shown between the symbols? If it is anything other than "0" type in "0" and press ENTER. Redraw your lines. Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 Re: ELEVATION. Refers to the height off the drawing plane. Normally AutoCAD will draw everything at a "Z" elevation of 0. Draw a line and either check its Properties or do a List on it. What is "Z"? It should be "0". Quote Link to comment Share on other sites More sharing options...
AutoCutter Posted November 18, 2010 Author Share Posted November 18, 2010 Hey ReMark, you are right. in the THICKNESS command the default value was "5". I changed it to "0" - now it works correct. Thx for the hint!!!!! Awesome. but in my point of view there's no logic why autocad should act like it does... Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 "but in my point of view there's no logic why autocad should act like it does..." First...What are you referring to by the above statement? Second...You're welcomed. Quote Link to comment Share on other sites More sharing options...
dbroada Posted November 18, 2010 Share Posted November 18, 2010 isn't that what I suggested? Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 isn't that what I suggested? Yes Dave that is exactly what you had suggested. But the OP admitted he was a real novice at AutoCAD (started 2 days ago) so I took that as a sign he wasn't familiar with "how" thickness was set. Beats me how it got set to "5" in the first place unless he was fooling around trying to create a 3D drawing. Quote Link to comment Share on other sites More sharing options...
dbroada Posted November 18, 2010 Share Posted November 18, 2010 I intended taking it in little steps but had some paid work that needed doing so I'm glad you were around. Quote Link to comment Share on other sites More sharing options...

AutoCutter Posted November 18, 2010 Author Share Posted November 18, 2010 First...What are you referring to by the above statement? I'm refering to Autodesk. I was just wondering why Autocad uses THICKNESS on a drawn polyline without asking for it. that's it. I didn't intend to offend you. but thx, the both of you, for your help!

ReMark Posted November 18, 2010 Share Posted November 18, 2010 Honestly, I do not know why. Since I got used to working with solids I've never had the urge to use the command. Maybe someone more knowledgeable than myself can provide us both with a good reason. Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 From AutoCAD Help file: Thickness Use the thickness property to give objects a 3D appearance. Note however the object is still considered to be 2D. Quote Link to comment Share on other sites More sharing options...
AutoCutter Posted November 18, 2010 Author Share Posted November 18, 2010 "THICKEN" would be a way to generate a real solid out of a surface. Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 18, 2010 Share Posted November 18, 2010 PressPull works just as well. Quote Link to comment Share on other sites More sharing options...
