AutoCAD - Polyline problem 4

[nat]

Hi there,
I have just started out learning AutoCAD and am stuck with the polyline.
The problem I am having is joining polylines.
Eg. I have two circles 100mm apart I have to join the two with an arc of 200r. I am unable to join them with the lines intersecting in the correct place.
Also I've had problems with joining polylines together.
Appreciate a hand
Thanks
Natalie

I think the problem may lie in the circles. They are entities and cannot be made into polylines (if i'm wrong let me know). I was able to make a polyline of the two segments of circles and an arc connecting them only after I trimmed away part of the cirlce.

Qshake is right. Circles cannot be a polylines. You must define a circle with command called "Ellipse" (circle will be an ellipse with equal radios)

...or you can make polyline from circle using Boundary.
Boundary command makes polylines or regions.

To join two entities making a polyline, their ends have to meet, you cannot for example join circles in a polyline or 2 crossing lines. If you use the block command you can join several entities. Steven van Els
