Dear all
I have one problem about TT point (OSNAP).
EX: I have Rectangular ABCD (AB= 200 x BC= 100mm), I want to cut the line between AB (EF = 100) by Break command and use Temporary track point But it's not exactly, I don't know why, Could every body help me
 
Thanks alot

Why use Temporary track point?
 
Use Break at point and OSNAP at Endpoint/Midpoint etc. instead,
same thing if you use Break, select F for first point and then OSNAP at Endpoint/Midpoint for first point and second point.

Thanks for your reply, I can use another methods, but I want to know about this method. Why it isn't exactly.
