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

[Bogbadbob658]

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

 

 

As previously mentioned by JD 'group' will allow you to select all lines in one go as would creating a block. The only way you create using a single polyline is to trace back over some of the sections of cube.

See attached file. You can not join 2D polylines they have to be 3D polylines. I can't say I used the lowest number of segments though.

All right!

this also worked and it was the fastest way; 3d polylines must be open(not loops: I drew a square with one continuous PL instead of four individual ones and it could not be 'joined' with the others because it was a closed contour), that is the only limitation. After that,you can freely join them regardless of the plane they are in .

So,

Thank you rkent and Dadgad !

Actually,it did not work: it did not unite all the lines: one could not be joined.

I tried again and it did not work.

 

Sorry I didn't reiterate that need in my kudos to rkent, yeah as previously suggested by JD and ReMark, using BLOCK, WBLOCK or GROUPING

would ultimately be required to unitize the entities.

Bogbadbob is right, you could retrace over some of them, but personally I don't care for doubling up like that, I'd rather BLOCK or GROUP them.

Thank you for your inputs !

I think all of your contributions will help anyone to:

-create a block

-understand the limitations on 2d polylines and 3d polylines and quickly go around them.

Thank you!

easiest is to GROUP or BLOCK the object i guess

I am completely lost in your problem description on why you are trying so hard to get these lines as a single entity.

I do not see any need for single geometric entity (rather than group or block of multiple simple lines)?

-creating a BLOCK worked

-uniting the 12 3dpolylines did not work

the problem has been solved by uniting the lines in a block . I now have a cubic block that I cunningly named... 'Cub' and it is exactly what I wanted AND I learned how to make a block and how to set a solid's transparency by placing it in a separate layer and setting that layer's transparency to my liking .

so thank you!

when I stated that it did not work I was referring to the 3dpolys that followed the solid cube's edges.

Well now you have tried a bunch of things that might come in handy for future designs.

I haven't experimented - but I think there was additional 3D spline joining capability added to later release (I could be wrong on this).
