how do I join the lines that form a cube, not solid. I need single cubic line-object

**turboCAD** · 16th Oct 2012 05:09 pm

hello!
I drew a cube using polylines by changing ucs.
I want to join the polylines so that the cube contour becomes one single object.
Since the lines are in different planes I can not join them.
How could I unite those 12 lines so they become a cube non solid(I plan on placing a sphere inside some of the cubes and then use "shade" for visualization so if the cube is solid I won't see the spheres).
Thank you!

You could have just as easily created surfaces using lines.

If you can't see inside the cubes what is the point of putting a sphere inside?

Try drawing a square in plan using a polyline. Copy it form 0,0,0 to 0,0,x where x is the length of the side. Change the ucs to an isometric view (doesn't matter which one). Make sure you have snap end on and then draw ploylines from corner to corner to complete the cube.

If it has to be a solid then draw a box then extrude it. Now shell the resultant solid. You can put your sphere inside the box before or after you have executed the SHELL command (Solid Editing panel).

the sphere is circumscribed by the cube made from lines NOT solid cube(the cube is just a frame I use for aligning the spheres).
sphere+cubical frame around it form an atom that I will use repeatedly
That is why I need the cube to be made only out of lines that do not mask any spheres.

Cube with sphere. Cube is a solid. The one on the right has been sliced open. 2Dwireframe is the visual style.

Group the lines
or
make the cube solid and apply transparent texture.

reading the clarification of your problem description you then might block the sphere and group.

I need the cube to be one continuous polyline block made of its 12 individual lines so that it is easy to copy/paste and I do not have to select each of the 12 lines separately

See post #6 and 7. The cube is a single entity.
