How can I have one hatched object supersede another?

I first drew a large rectangle that I hatched with a brick pattern. Then, I drew a two smaller rectangles inside the larger one to serve as a double door, and I hatched this with a solid color. It appears that the door hatch is constantly underlapping/overlapping the other brick hatch whenever I zoom in and out in model and paperspace. If I use the command REGEN it is completely solid, then I zoom out a little and it's partially solid, use REGEN again and its solid, etc. I don't know if it is because they are on the same plane and are competing with each other, perhaps there is a way to set one over the other without physically moving the door outwards along the Z axis?

 

I've attached a pdf of what my problem looks like. Thanks for the help!

Hi,

Have you tried to subtract door rectangle from wall rectangle at first, than draw new "door" rectangle in place of subtracted and hatch it?

So I'm trying SUBTRACT and SURFTRIM with a test cube and a smaller rectangle for the door that I extruded so that it is within the larger test cube and flush with the outside of the larger cube. But, neither command seems to be subtracting anything, and I am following this documentation here https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC.... I must be missing something. 

 

 

EDIT: In case that made no sense, I've attached another pictures.

Hi @Anonymous,

 

I am confused :cara_con_una_leve_sonrisa:

 

Can you attach your file? I am happy to help (if I can understand what you are facing)

You probably are trying to us SUBTRACT command incorrectly.
If both objects are 3D Solids (cube and smaller parallelepiped), than the workflow is:
- start SUBTRACT command
- select large cube
- hit Return to confirm selection
- select small parallelepiped
- hit Return to finish the command
You will get cube with subtracted part as the result of the SUBTRACT command.

Thank you, worked flawlessly, it was not working because I was not hitting ENTER after each selection. 

 

So in case anyone has the same problem later on I:

 

1) Drew a rectangle on a larger cube in order to resemble a door

2) EXTRUDE the rectangle into the cube a little bit

3) Subtracted out the newly extruded shape (using Maxim's commands above)

4) Re-drew a rectangle at the surface of the cube where it originally was

5) Hatched the newly drawn rectangle to create a metal looking door on an already hatched brick building
