Extrude

(3D only) Used to create a surface or solid — a complex 3D element generated by linearly extruding a profile element (line, line string, arc, ellipse, text, multi-line, complex chain, complex shape , or B-spline curve) a defined distance. Surfaces formed between the original profile element and its extrusion are indicated by straight lines connecting the keypoints.

Tool Setting	Effect
Type	Can be Surface (not capped) or Solid (capped).
Orthogonal	If on, the profile element is extruded orthogonally.
Distance	If on, sets the distance, in working units, the element is extruded.
Spin Angle	If on, sets the spin angle.
X Scale	If on, sets the scale factor in the x-direction. see footnote 97
Y Scale	If on, sets the scale factor in the y-direction.
Both Directions	If on, the profile element is extruded in both directions.
Keep Profile	If on, the original profile element is kept in the design.

To extrude a surface or solid

Use the Element Selection tool to select the profile element.

Select the Extrude tool.

Enter a data point to define the start point.

Enter a second data point.

Distance	Defines extrusion's
Off	Distance and direction
On	Direction

Alternative Method — To extrude a surface or solid

Select the Extrude tool.

Identify the profile element.

Enter a data point.

Distance	Defines extrusion's
Off	Distance and direction
On	Direction


Extruding a solid graphically (with Orthogonal turned off). Identify the profile (1). Define the distance and direction (2).


Extruding a solid using AccuDraw to constrain the extrusion distance (D) and direction (to make the extrusion orthogonal).


With Both Directions turned on, the profile is extruded in both directions by the distance (D).

Key-in: CONSTRUCT SURFACE PROJECTION

Although the extrusion distance can be specified as a tool setting, it is generally quicker and easier to type this distance into the AccuDraw window.

The Place Slab tool provides a faster way to place an extrusion with a rectangular cross-section. The Place Cylinder tool provides a faster way to place an extrusion with a circular cross-section.
