I have a tangent, curve,tangent. I made it into a single polyline. I want to rotate it so that it passes through a point. I compute that it needs to rotate by 0å¡04'04" (to the left). So I pick edit...rotate...by pick. I pick the polyline, then the base point (end), and type in the angle. It doesn't seem to work.
What is the proper way to do this?
You can type rotate and select the polyline. Then pick the base point for the rotation and type "r" enter for reference. Then pick the base point, then the point on the curve that you want to go through the other point. I think the conmand line will ask for the new angle and all you have to do pick the point you want it to go through.
Draw a circle, center point at the end of the polyline, set it to radius and pick the point. Now you should have a circle, center point at the rotation end of the polyline and through the point.
Rotate, pick end of polyline, Reference, @, second point is the intersection of the polyline and circle, rotate to point:
thanks, I am a basic cad user, still trying to learn the basics of carlson. I did get it to work that way

Rotate is an AutoCAD command, so you must type in the command the way AutoCAD wants it, you would type:
0d04'04" or since there are no degrees 4'04".
The default for AutoCAD is rotate to the left. Been this way since I was in DOS AutoCAD 10.
If you want to rotate by degrees only, the d is not required.
In the "Edit" "Rotate" pulldown you have another option "Rotate by bearing" and you could type in the bearing using quadrant method, which would be typing 400.0404 as the last entry.
Jones's method is not always perfect. I draw a circle from the rotate point through the point I want to rotate through and either trim or extend my polyline to the circle. It incrementally changes the length of the polyline, but hey, most surveying is to the nearest 0.01' anyway.

For some reason the rotate certain number of dms entry does not work on Carlson like it did on AdCad and as most pure COGO routines are set as standard rotation.
Once learned the "snap to" or "match" rotation procedure is fantastic.
I mostly COGO with outside Carlson Surveyor1 and make my calculations there and get the GIOGO values sound and save to a points file to upload to Carlson and do the minor computations and simply draw inside Cadd to produce my product.
Use the Align command. Your first Source and Destination points are what you're holding. Your second Source and Destination are the direction. I usually end with that, even though it'll prompt you for more, and for scaling, which I don't do.
I'm don't know for sure but doesn't rotate need decimal degrees to work ?

Use the angle as a decimal number. Should work fine then. i.e. 00å¡04'04" = 0.0677777777å¡

xD y' z" is the conventional method in AutoCAD - makes it simple since you don't have to convert to decimal degrees.
42å¡27'12" is entered as 42D 27' 12"

Very handy command for cad work.
One caveat on the align command, it is a 3d command so make sure that osnap z is set to 1 or all of the picks are at the same elevation or you will get some very perplexing results.

Hi Jim.
Just FYI - if you want to get a degree symbol try holding the ALT key and then type 2 4 8 then release the ALT key.
You should get the å¡ symbol then. All keyboards have a secondary set of symbols built into them. Here is a link to a good list.
I know Carlson likes the D for degrees. It works.

Good point. I never have anything in 3D, except contours, though. And I'm never aligning about those.

Mapman,
I use that all the time in docs (as well as ALT 241 for å±), but have never thought of using it in the command line in AutoCAD..." D" has worked in AutoCAD since V2.1...
