Hello Daily AutoCAD readers,
POLYSOLID is probably one of the most useful tools for creating 3D solid entities. It is available since AutoCAD 2007. By using this command, you can draw solid entities that are in forms of polylines that has constant width and height very fast, just like using the POLYLINE command. The most useful way of using POLYSOLID command is drawing a 3D wall.
The main difference among the options that appear when you run the command, compared to POLYLINE command, is options that belong to entering width and height.
Command: _Polysolid Height = 90.0, Width = 13.0, Justification = Center
Specify start point or [Object/ Height/ Width/ Justify] <Object>:
I suggest that you make the “Height” settings first, and then the “Width” settings. Later on, you can use the other options. Among the other option, the most useful one is “Object”. It is used for converting 2 dimensional LINE, ARC, CIRCLE and POLYLINE entities into POLYSOLIDs. We already know how to draw these entities very well, so it will be very useful to use these entities for creating our 3D POLYSOLID entities. Below, you can see two examples for this, one of them is converted from ARC and the other one is converted from a 2 dimensional POLYLINE entity.

However, if you insist to draw your own POLYSOLID entities, then I suggest that the “Justify”, thus aligning, command will be quite useful for you among the height and width options. Unless you enter something else, it will draw from the center.

Fig.5
When you start drawing, then the active options will be ARC and UNDO. I think, there is no need to explain about these options. Of course, you can do other examples than the 3D wall by using POLYSOLID. We will be happy if anyone from mechanical disciplines can send us some examples.
That’s all for today. Have a nice day.

I could not get 3D polylines in 2007 to extend or trim to another 3d poly, all the same height and elevation. Did 2008 cure this problem, or would you like a sample of what would not work?

Hello Lyle,
Of course not
Please send me your drawing, i’ll inspect what is wrong orhan @ taliasoft . com

Hi Mr Toker
My question is how I can subtract a text in 3D

that command is really helpful to convert 2D object to 3D object
