Nomally i use hole option first in wireframe option when making hole on surface design with thickness.But recently i saw a man who make hole on the similar model, that i made, ising pocket option in prt design mode. I dont know hw he did.
How can make a hole using pocket option on the surface design with thickness in gsd mode
Many users will add holes to their solid models in CATIA with the Pocket command in the Part Design workbench. Some will also use the Groove command for holes. But the Hole command is preferred and it does provide many more options, such as hole type, thread, etc.
But the Pocket command only works in Part Design - it doesn't exist in GSD.
