Creating a 3D solid from lines (Help)

Hi, I created a 3d object using the line tool but it shows just the outlines I made. I need help in changing the object to have solid faces all round..

Think about it: LINE is a 2d object. How would it suddenly become a "solid with faces" just because you drew something in a Z elevation :cara_con_una_leve_sonrisa:

Do you need to start over using actual SOLID objects https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2018/ENU/AutoC... and https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoC...

Your best bet and easiest way to make the object into a 3D solid at this point is to:

1) Use the "Join" command to join sections of lines together into closed polylines, 

2) Use the"Extrude" command on all closed polylines, extruding them further than the extents of the shape you want

3) Use a combination of "Intersect" and "Subtract" commands to chisel out the shape you want.

 

In the future I'd suggest using commands more aptly suited for 3D Modeling such as Box and Wedge.

 

Hope this helps!

Hi,

Noticing that you made a good effort to create all of the linework that would represent the edges of your 3D objects.  A reasonable thought certainly in "how can I make this a solid model".

 

It appears that you only have flat faces for this model so I can suggest that you create surfaces (faces) for each of the boundary areas.  Then you can use SURFSCULPT to generate the solid as long as you have all faces pre4sent and the surfaces form a closed model.

 

BTW... A more complex model would surely require better technique, as recommended by others.

 

Best,

Blaine
