If the block is not dynamic this will return the name of the block (cdr (assoc 2 (entget (car (entsel "\nSelect Block : ")))))

I never used R11. I went from R10 to R12, but that screenshot brings back memories.

I have AutoCAD R11 for Windows running now, so expect a video about it by the end of the year.

You cannot offset counterclockwise, only left or right, and that is dependant on how the xline was constructed. Please look at the modified attached drawing as there are inconsistencies Block(1).dwg

Hi, you can try to implement this routine for your problem along with your already coded solutions by @dlanorh http://www.theswamp.org/index.php?topic=55550.msg597049#msg597049 It should work for blocks and dynamic blocks, but for xrefs that are complex, there are some lacks I hope someone can help to be overcome problem... Regards, M.R. [EDIT : I know this is hijacking topic, but if someone is willing to try to solve the problem from posted link, in attachment is my *.zip posted at theswamp...] findclosestpointtonestedinblkref - problem with xrefs.zip

To convert from degrees to radians, you would divide by 180 and multiply by pi. To convert from radians to degrees, you would divide by pi and multiply by 180. Such functions may be defined in the following way: (defun dtr ( a ) (* pi (/ a 180.0))) (defun rtd ( a ) (* 180.0 (/ a pi))) Provided with a tangent of 0.26 recurring, you can obtain the corresponding angle in radians using: (atan 300 1125) = 0.260602 radians Alternatively: (atan 0.266666667) = 0.260602 radians Using the rtd function defined above, you can convert this to degrees: (rtd (atan 300 1125)) = 14.9314 degrees
