Which of the following is true about creating 3D POLYSOLID in a AUTOCAD?

• POLYSOLID can only have straight segments.

• POLYSOLIDS can only have curved segments.

• POLYSOLIDS can have both straight and curved segments of constant height and width.

• POLYSOLIDS can have both straight and curved segments, but the height and width must be different.

Which of the following is true about creating 3D solids in AUTOCAD using the POLYSOLID command?

• The PSOLWIDTH system variable only sets the default height for the 3D solid.

• The PSOLHEIGHT system variable only sets the default width for the 3D solid.

• The PSOLWIDTH and PSOLHEIGHT system variables set the default height and width, respectively, for the 3D solid and also can be used to convert existing 2D objects to 3D solids.

• The PSOLWIDTH and PSOLHEIGHT system variables set the default height and width, respectively, for the 3D solid but can't be used to convert existing 2D objects to 3D solids.

When creating 3D objects in a AutoCAD, which of the following best describes the similarity between 3D polysolids and 2D polylines?

• 3D polysolids are completely different from 2D polylines and cannot be used in the same way.
