complex linetype issue

[MKH-VB]

I've received a file from a surveyor, and it contains complex linetypes.  If I choose to "reverse" the polyline, the text does not flip.  What is the parameter within the linetype description that will allow me to reverse a polyline and have the text flip?  thanks

Hi,

Your linetype (.LIN ltype definition) used for the respective line or polyline may use the "upright" alignment code (always readable). I suggest to follow this link that may help . >> Click <<

Wout the u option work if I have the drawing with the linetype xreffed into another dwg, with a dview twist?

Try the following example. I created two linetypes for overhead electric lines, one rotated 180 degrees so the text is always readable.  The setting "A=180" is the only difference.

*OE,Overhead Electric ----OE----OE----OE----OE----OE----OE--
A,.5,-.2,["OE",STYLUS,S=.1,U=0.0,X=-0.1,Y=-.05],-.2
*OE_180,Overhead Electric-Rotated180 ----OE----OE----OE----OE----OE----OE--
A,.5,-.2,["OE",STYLUS,S=.1,U=0.0,A=180,X=-0.1,Y=-.05],-.2

Or from AutoCAD's own Help:

Check the linetype definition if you have access to it, for the rotation part of the text-inclusion entry:

Not sure what the "a" variable represents

See the right side of the first image in my previous Reply.  Or better yet, go to Help and look around.

Create those linetypes and play around with the A and R settings.  Draw some lines in all different directions and you'll see what the settings do.

Is it even permissible to have two rotation entries?  If it doesn't give you any invalid error, I assume the second one rules, and the first one is ignored and therefore removable.

I'm no linetype expert.  I'm sure I created these through trial and error.  I do get a different result if I take out the "U=0.0"

That would imply that if there are two rotation entries, the first one wins.

I did some testing... To get the result I wanted, both rotation factors have to be in there.
