i have 2 questions that really bothering me all the time. First is, how do I make straight loop cut based on the image below in red line. 2 lines which is not straight and not in same angle each other. The second question is i want to move slide along the edge, just want to make my orange line straight align with my blue dot vertex. Again, 2 lines which is not straight and not in same angle for each other. Actually I can do it easily in max but I want to improve my blender skill so I can leave this expensive software. Humble thank you for your help.
