change center of circle after use USC

[xuantientutungXUK6E]

hi guys,

i want to change the center of circles to usc cordinate.

but after i change wsc to usc, i use getproperites 'center.... and the point center is still in WSC.

does it anyway to change it to new usc.

hope i can get any suggestions.

thank you.

Use the TRANS function

(trans (getpoint)  0 1)

hi,

i need to change the coordinate of the circle center from WSC to USC. But after i change Autocad to USC coordinate, the center i get when i use the command (getproperties 'center...........) is still in WSC.

So use (trans (getproperties 'center........) 0 1), the point will change in to USC.

thanks.

try these code, and use F2 to open consle and see what it be

(setq pttrong(getpoint ))
(setq wp(getpoint))
(command "_.ucs" wp pause pttrong) ; code to make UCS

(setq cirpt(getpoint )); code to choice center of a circle

(setq cirpt1 (trans cirpt 0 1) ); code change cirpt from WCS to UCS.

(princ cirpt ) 

(princ "change to" )

(princ cirpt1)

[That's WCS and UCS, by the way -- initials for Coordinate System.]  Depending on how you need to use the information, there could be a much easier way.  If you don't need to save it in code for some kind of calculations or the like, but you just want the center to be reported  to you in coordinates of the current UCS, just use the LIST command.
