Can you give me a brief on Autocad command that you recently came across and find very useful?

Command "NCOPY" Advantage : You can copy entities from Xref files without opening the parent file...
Disadvantage : You can only select single/individual entities means window selection not possible...

Was having difficulty adding Global width to circles.
Previously i used to draw a polylinw (PL) on top of a circle.
Then delete the circle and gave global width to the polyline.
Then i found a easy way to do it.
1- Use the DONUT (DO) command specify the inner and outer diameters.
Select the donut, modify properties(MO) add global width.
2- Start by making a polygon (POL) with4 sides.
Check inscribed (I) in circle when prompted.
Next specify your radius.
That will create a square.
Then select polyline edit (PEDIT), then select fit (F), then width(W).You have a circle with a global width!

Command "extrim" : You can trim or cut the multiple lines by one click. just select the source object and click in or out side of required area which you want to cut or trim.

Advantage: you can select any rectangle, circle, poly line, line, arc, image and text Disadvantage : You cannot use select sub commands i.e. fence, window, last etc

Command "xclip" Advantage: You can clip nested object or any entity from Xref. files without opening the parent file.

Disadvantage : You will save only the clipped part rest you will lose.
