Sketching inside the box

[damjanRBUXA]

Can someone help me with this.

I have a box and I like to sketch inside that box. I like to make some support inside the box on wall.

But problem is I have to do that with box in some angle to create something on walls inside the box.

Is it possible to to cut box in half in some virtual way not real and make on that walls whatever than disable that and box is whole again?

I tride to make sketch than check "slice" in menu, but box is still the same.

Inspect|Sectional Analysis will allow you to work on the inside of a box.

ok I found it.

now how can I make a square from a line of bottom box, so it will stick on the wall and bottom, now when I try it freally flows and can be a micro mm from bottom or a wall of inside box?

And dimensions inside the box doesn't work in this mode? is there some way to use dimension?

When I try to make another support at the bottom with section analysis it makes square on the other side of the box.

Explore the many options of the Extrude command (From Object, To Object, Two Direction, etc.).

It is also not necessary to have the box body visible while sketching.
