i want them to make plines not splines. the drawing was created in microstation so that may be the issue. is there a fix? thanks.

when i join some of the lines with an arc it turns into a pline. others turn into spline. i don't know why. once it's a spline then i can't use it and converting it to a pline makes a bazillion little segments along the arc. is there a setting somewhere?
You of course will need to replace the ellipses with arcs or use Flatten on them.
If you draw ellipses regularly you may want to set pellipse to 1 instead of 0. 1 will create a pline ellipse, 0 will create an ellipse.

nope. not ellipses. all at 0'. i just had to redraw them to get them to join correctly. must be a microstation thing. thanks anyway.

When importing a DGN AutoCAD creates splines for 3d polylines. I'm not sure if it does the same for whatever 2d polylines are in MS. As far as I know, all arcs from a DGN are imported as ellipses, so other than recreating them you might be out of luck.
Have the same problem. Looked at the arc properties and saw that normal Z was -1.
Did the 3dmirror thing and now i can join them without turning the whole thing into a spline.
It seems like its the Join command that causes this. Using the pedit command still works like it should. AutoCAD please fix this. Join is easier to type than pedit
I've had the same problem.
I've fixed it by: explode (a few times) till they are all just lines and arcs, afther this use flatten. After this you can use Join without them becomming Splines. (worked for me)
Must be an DGN error, because this also was originally a DGN file.
I've had the same issue before. Usually I just join a piece or two at a time checking it stays a pline. Eventually I'll find one or two arcs that for what ever reason cause it to become a spline. I'll just redraw those.
I just wanted to confirm that elevations present in entities using the join command seems to be the culprit. Make sure that all your Z values are common. This is regardless of where the entities originate from. I joined arcs and lines that had differing Z-values, and it created a spline.
As for Microstation, OMG what a disaster. Bringing those translated entities under control is a nightmare.
