Ucs?

Anyone here can give me a guide that how to rotate the UCS icon, angle by angle. This is my big prolblem.

This tutorial should cover the basics for you. If you are in the Ribbon view on 09 some of the commands may be in different locations, but under the toolbars they should all function the same.

OK tnx Sir.. i'll practice it right now.

... i use ucs base on by face and not by coordinate. i.e. instead of sw,ew,nw,etc- i set ucs>fr(front). its keep me faster track where i should have draw my lines.

I set up some quick keys to automate manipulating the UCS and 12 or so quick keys take care of a large portion of what is needed for the 3D that I do.

 

In my acaddoc.lsp file I have the following for 3D.

(DEFUN C:U3 () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "3")(PRIN1))

(DEFUN C:UB () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "BOTTOM")(PRIN1))

(DEFUN C:UBA () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "BACK")(PRIN1))

(DEFUN C:UF () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "FRONT")(PRIN1))

(DEFUN C:UL () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "LEFT")(PRIN1))

(DEFUN C:UM () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "MOVE")(PRIN1))

(DEFUN C:UO () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "OBJECT")(PRIN1))

(DEFUN C:UR () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "RIGHT")(PRIN1))

(DEFUN C:UT () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "TOP")(PRIN1))

(DEFUN C:UV () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "VIEW")(PRIN1))

(DEFUN C:UW () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "WORLD")(PRIN1))

(DEFUN C:UZ () (SETVAR "CMDECHO" 0)(COMMAND ".UCS" "ZAXIS")(PRIN1))

(DEFUN C: pW () (SETVAR "CMDECHO" 0)(COMMAND ".PLAN" "WORLD")(PRIN1))

(DEFUN C:X9 () (SETVAR "CMDECHO" 1)(COMMAND "UCS" "X" "90")(PRIN1))

(DEFUN C:Y9 () (SETVAR "CMDECHO" 1)(COMMAND "UCS" "Y" "90") (PRIN1))

(DEFUN C:Z9 () (SETVAR "CMDECHO" 1)(COMMAND "UCS" "Z" "90")(PRIN1))

 

To understand what each line does look at the two characters after the (DEFUN C: .

X9 will rotate the UCS 90 degrees around the X axis., hitting enter will rotate the UCS around the X axis 90 more degrees. Same idea for Y9 and Z9.

 

If you have a line you want to align the UCS to, try UO, for UCS, object. Type UO and pick an object.

 

Type UW and PW to set UCS and Plan to World to get you back to a default starting point.

 

Type UCS, enter and the command line and look at and explore all the available options.

I find UCS, 3 point, to be the easiest to use...

i guess everyone has its own approach to their most comfortable ways.....:wink:

 

... and merry Christmas to all and have a profitable year!!! :xmas:

@rkent

Can you give me the complete LISP code to copy, so that i can do and make a source, Or is that the code anyway?

I would have thought the simplist way was to use the UCS 'Z' option and set the angle to 1. If you want the view to rotate rather than the ucs then set 'ucsfollow' to 1.

... here is a lisp that I've got a month ago.. i would like to share it....

Snapline.lsp

Can you make a sample how to use that LISP?

I'll give you an edited one by typing qw, then click on your reference line... going back to the normal ucs, just type qw>0.

before i forget. this runs only on plan view.... (sowe)

Snapline.lsp

That is the code, copy and paste it into the acaddoc.lsp. If it doens't exist then open a text editor, paste, save to that name and in a folder in the search path. For search path go to Options, Files, support folders, see what is in there, add your own if you want. I keep all my customization files in an acad folder under my documents.
