I've been trying to create a 3D cube outline like in the image below:
I want the outline to be hollow so I can place another 3D image inside of it.
Can somebody please help me? I've been looking for tutorials everywhere but can't seem to find an answer. Thank you in advance.
Start with 2 squares (with the Rectangle tool) for the front and back facets.
Use the Line or Pen tool to connect the corresponding corners.
Select all 6 objects and Group. You will notice that the outer corners are not right.
So with your cube selected press Cmd/Ctrl+5 to make a guide of everything.
Now with the Pen tool click on each of the 6 outer corners of the guide cube and close the path by clicking where you started.
Then do the inner lines with either the Pen or the Line tool. Group.
