[benH27]

coming from 3ds max 2015 when i'm editing a object i can see the edges that are being changed. i cant in 2017

this is 3ds max 2015 before and after doing a weld

and this is how max 2017 looks 

Max 2017 after

how can i get max 2017 to display the same way 2015 did?

hi dear friend i think your system properties not meet the requirements of 3ds 2017 that is why you facing such problem or if you are work on 3d graphics of ATI graphic card use direct software opengl mode.

thanks
