Drawing a parallel line to unknown angled existing line

[berol]

In an old Ver 2000 drawing, how would one adjust the cursor parallel to an unknown angled line in that drawing so a parallel line to it could be drawn? Also, please, if there are other ways to accomplish the same. Thanks, Berol

Type in UCS then OB (for object). Select the inclined line. That's it. Now to reset the UCS, type in UCS then W (for World).

Another way is to use the Parallel Osnap Option. While drawing the required line, SHIFT + Right Click and select the Parallel option there. Now move the mouse over the inclined line and you'll get a Parallel Marker. Done! Now you can continue with the parallel line.

Moreover, you can even use the Offset command. It involves less steps than the others and is more "flexible".

make a line perpendicular to the first line from any point using osnap perpendicular option. now make another perpendicular line to the second line. third line is parallel to the first line
