linewidth not line weight

[neyes_ice]

can anyone help me? i can't seem to specify a linewidth to a circle, unlike in a polyline. thanks a lot. im using autocad 2007

Hi Neyes_ice,

Pick the circle and change the line weight to a greater value - 0.30mm or more.

Hope this helps.

thanks sparklerach. but that's not the solution im looking for. looking for linewidth not lineweight. you can't use the poly edit command on a circle. i've tried donut but its too time consuming.

You could use the Arc option of the PLINE command to create half of the circle, then mirror it across to create the other half. Then join them together with the Join option of the PEDIT command. Now you will be able to change the line width with PEDIT.

i could do that, but its still time consuming. i'm involved in tracing maps, so there are situations that i need diffent sizes of circles. so ideally, i there is any... i need to create cirlces that i can manipulate the linewidth instantly.

You only need to create the circle once and then just copy and scale it according to the size you require. It doesn't take more than 15 seconds to copy, scale and change the line width of the circle once it's created. I don't know of any faster or easier way to accomplish what you are trying to do. Perhaps a lisp routine could be written to create the circle based on input from the command line, but you would still have to step through the routine every time to input the numbers, so I don't think it would really be that much faster.

I use donuts when drawing circles of a certain width.
Works a treat for me.

I was about to suggest that.

Hi! neyes_ice,

linewidth not line weight…….Why?

Are the line widths of your circles to be consistant, regardless of diameter?
If so, then sparklerach idea would be the quickest solution. However if you were to create a layer specifically for drawing these circles you could preset the line weight first thereby doing away with having to change them later. Faster still!

However,you must have a reason for not wanting to use lineweights.

Does it matter if the line width appears differently on different sized circles?
If not, then Cad64 idea would be better. Create one according to his idea at one unit in diameter then block it.
Insert the block and scale it to suit. The bigger the circle, the thicker the line will appear.
Further to additional posts appearing ( cymro/dbroada), yes, making a donut and blocking as above should produce a similar effect.

But then maybe you want to set the thickness depending on the circle, which could be any size for whatever reason!
So for example, two circles of the same diameter could have different line thicknessessessess depending on what you want to use them for.

How wide a line are you looking for?

P.S. Interestingly, an exploded donut reverts back to 2 arcs, which if you then join again make the very same polyline that Cad64 was talking about. Give that a width and it becomes a donut again!
Am I going in circles?

we work off of lineweights here. but there are some things i like to have linewidths, just to help destinguish where/what it is throughout the drawing, that's probably what he's wanting to do. but yeah, can't do it to a circle, gotta be Polyline Arc.

Cad64 has the best solution, make them, set them aside, and copy them where needed. or, start making blocks depending on how much you're gonna need.
