3ds max surface cut problem

[+ravenclaw_007 7,633]

i would like to know if there is a possibility to keep the interfacial tension after cutting a surface

 

on the picture you can see that the airbrake is no longer showing the same surface tension as the rest of the fuselage resulting in a different shadow representation and a sharp edge on the cut surface

 

any info is welcome

you can meshsmooth around the cutout area...it aint perfect but a good paintjob will hide the resulting edges.

i try that but in this particular case it is not working , the cut airbrake is the lower part of the fuselage and appears much more flat compare to the the cylindrical shape of the fuselage

in your case the cut parts are with the same cylindrical shape and radius as the engine housing , on the RF-8 the lower part is almost flat with a very large radius compared to the fuselage side

 

i was looking to all options if i can find something that let the cut part still have the surface tenion of the fuselage but sofar nothing

Reweld the vertex's around the cut to the fuse, should fix the surface tension. ?? Or is it a separate mesh?

Sometimes you need to add faces to convex surfaces before you cut, especially in convex areas and or areas where you're transitioning from a hard edge into a convex area ...

 

Trick I use when cutting gun ports and air brakes is to detach the polys of and around the the area I need to cut then sub-divide or tessellate, make the cut then go back and snap-weld it back in and clean up superfluous vertices leaving the extra faces necessary to keep my surface tension clean.

thanks for the help

 

i did cut an additional part from the fuselage and welded it on to the airbrake , it fixed the problem to an acceptable level i think , the drawback is that the cutout for the airbrake is now a bit larger than it should be
