Joining lines

[wings]

Hi,

I have 2 questions that could actually be asked in 2 separate forum subgroups (this one and the plotting one), but am posting here as to avoid posting the same thing twice in the 2 separate subgroups.

 

1)I am having trouble recalling what command makes plines join at corners so that the corner is mitered, and not at the center of the line (when a width is specified).

 

2) Also, when I plot, I get the same look (non-mitered corners).

I am using a ctb file, and I have my "line end style" set at "butt", and my "line join style" set at "miter", but I still get a look similar to the image posted.

I believe it has something to do with the fact that the polyline is something other than continuous.

My quick test.

Have you tried lineweights instead of giving a width to the polyline?

 

It may work for you.

Years and years and years ago (back in the last century) before ink-jet or laser plotters we used pen plotters.

I remember showing students how to set end cap style so that thicker lines didn't appear as in Preview 1 (see attached).

Is that still in AutoCAD somewhere?

 

 

OK, I found it in Plot Style

Does it work with dashed, hidden and phantom lines as well?

 

The OP said he used that trick when it came to plotting but he was not seeing the expected results. Did he miss something else?

... "line end style" set at "butt", ...

 

Square or Round.

I thought I drew the Pline as one continuous pline, then closed it. I will have to check.

How does one change pline to continuous if this is not the case?

 

For plotting, I was using "butt". I will have to try square. The images that autocad shows for each of those end styles are not very clear.

Continuous in this case has to do with the linetype and not with how the pline was made. With a linetype other than continuous you are going to get the corner. You can use fillet with a size of 1/2 the width of the pline, or draw the pline with extra sections (not recommended).

I did not use "continuous", but I recall doing this before, in other versions of cad, and that there was a setting that gave the corners a clean look.

The keywords are "...in other versions...". Features change at the whim of the programmers.

This question comes up from time to time. I don't think that there is one good answer. Each one of the settings has it's drawbacks. It really depends on what you use thick polylines for. It may be a matter of choosing the least bad one unless you get lucky and one does exactly what you want.
