AutoCAD 2017 3D Shapes Aren't Viewable In Realistic Mode

Anonymous — Sun, 10 Dec 2017 13:05:02 GMT

Hi everyone,

Tl;dr:

- Made these two shapes: imgur.com/ytHRCyX.png.

- Can't view them in anything other than wireframes. I want to view them in realistic mode.

- Tried typical commands like Convtosolid etc with no success.

Full:

I'm a beginner user of AutoCAD but I can usually resolve any issues I face by looking up tutorials. So far I haven't been able to find a fix for this particular problem.

I have made two shapes; the first being a hexagonal pyramid and the other a square based hexagonal pyramid. Picture here: imgur.com/ytHRCyX.png.

I want to be able to view the shapes in realistic mode, but both shapes remain as wireframes in all viewing modes.

To try to fix this I have tried lots of combinations of PEDIT, Convtosolid, Convtosurface, etc. I always manage to make all my other shapes viewable in realistic mode using these commands, so I'm not sure what's different about these two. In some cases Convtosurface has converted the top and bottom of the shapes but not the sides.

Thanks for any help!

Hi,

>> I want to be able to view the shapes in realistic mode

The screenshots do not give us any information about what type of objects these are, lines, polylines, 3D-solids, surfaces, 3D-faces, ...

The dwg-file would tell us a lot more about what you have.

But only real 3D objects with at least surface informations can be rendered, e.g. 2 parallel lines do not know that they are connected by a surface between them. So the visual style "realistic" does not show you anything filled.

You need to have meshes or surfaces or 3D-solids.

For your geometry you should create the rectangle at Z = 0, a polygon with 6 sides on Z > 0, then use command _LOFT and select both polygons.

Hi, thanks a lot for the reply! Sorry I didn't post the file, please find it attached, hopefully it helps. I'll try to figure it out based on your comment in the meantime.

Yep, these are lines and lines can't be shown (rendered) as surfaces or solids. 😉

Let me know if you need more help.

A video with the steps needed is attached.
