AutoCad 2D :: What Is LWPolyline - How To Draw
Oct 29, 2013What is a LWPOLYLINE? What makes it 'LW'? Why would one use one? How can one draw one?

View 9 RepliesI have a drawing that I'm having issues with, all of the Lwpolyline that we have in our drawings are not filling in the arrow part.
I have checked to verify that the fill is on, fillmode is on, Apply solid fill is on on the Display tab of options.
It isn't a leader arrow, but I did verify that the Arrowheads are all selected to Closed filled. Regen does nothing as well.
We use only polyline when drawing. Plinetype is set to 0.
First problem is with J (join) command. Sometimes when we try to join different polylines it kills a vertex. Example if i have two polylines (they are not joined) that forms a rectangle it will join them but kill one vertex and turn it into triangle. This dosen't happen all the time.
Second problem i figured a way round for the problem above, if i use the pedit command and then use j the above problem never happens. But instead (also not every time) it turns the joined polyline into lwpolyline. So its all pretty anoing as we have to use convertoply.
Is there some other command than plinetype to resolve his problem.
I have three dwg files. Each of them have separate MrSID files (image files) attached by georeference. Each file also has one or more polylines and hatch objects on top of the image.
ONE of these dwg files is causing problems. EVERY SINGLE TIME I plot the dwg file, the hatch and lwpolyline objects are UNDER the image. So I have to copy the hatch on top of itself and delete the original--then do the same with the pline.
I recently wrote a lisp routine that was supposed to get the 4 coordinates of a rectangle (LWPolyline). It worked fine in *MY* tests. But when someone else ran it, the routine operated as though the order of the points had been rearranged.
How can I get the points AND the order in which they belong?
Here's a sketch to show you what I mean. As part of my troubleshooting, I had a lisp routine draw a new pline using the points gathered by my first routine. The result of that on the left. On the right is the result of that when someone else runs the two routines.
Here's the code I used to get the points.
(defun getplinepointlist(ename)
(setq ent(entget ename))
(setq ptlist (list))
(while (setq pt(cdr(assoc 10 ent)))

Note that you don't have neither the radius, nor the center of the circle, nor the central angle: you only know L and C, period.

I don't know what to do with my drawing Units and Scale.
I want to draw in Meters! But when i make a rectangle 30x15m it looks so small that i can't see it in my draw. Using my scale is 1:1 and Units Meters.
I tried changing my scale and my units and the rectangle still looks the same way it was. If i want something to look big, i have to draw in mm, for example, 30000x15000mm rectangle.
But, when i do that, everything go wrong...For example, when i draw a rectangle in mm (30000x15000) and i change the line style in layer command or when i try to hatch/linear dimension and etc all looks very small or very big.

Is there a way to convert an image file logo (jpeg or bmp) to a DXF file so I can get that into CAD and then maybe scale it to fit?
Most programs do really bad conversions!
I have also attached the logo as a .ai file (Adobe Illustrator) which I got off the net but I can't do much with that as I don't have that program installed.
