Create the straight line as a pline and assign a width.
Create the arc as a "regular" line.
Join them using the fillet command, choosing the striaght line first. This technique will NOT work very well for lines at acute angles.
The second suggestion is downright awkward. Break the lines at the intersection. Stretch the straight line to the left half the specified PL width. (See, I warned you it was awkward!).
The reason why lineweights won't work in this case is that the polyline needs to have a thickness (not to be confused with width) and will be used in a 3D model. We're trying to avoid using soilds for as many small, thin shapes we would need to have.
Yes, we're in the process of converting over to 2007right now. I was just asking what I thought was an very basic, easy question that I foolishly thought would return to me a easy solution that I needed to have right away. I guess the bottom line and what I will need to tell all the users in the office, is this type of simple polyline is not possible in 2005.
If you can draw it with even a *very short* line segment coming around the corner from the other line segment, and have the arc segment be a tangent continuation of that short line segment, it will fill in the corner, because it can do that in line-segment corners, whatever the angle.
How can I get polylines with width to join at the corners without the gap shown in the attached file?
