Part I: SolidWorks Basics
continuedl (^) Up to Surface. Up to Surface could probably be better named Up to Face, because the end
does not necessarily have to be an actual surface feature. This end condition may display a
warning if the projection of the sketch onto the selected face extends beyond the boundary of
the face. In that case, it is advisable to knit several faces together into a surface body and to
use the Up to Body end condition.
l (^) Offset from Surface. By default, Offset from Surface extrudes until it reaches a specified dis-
tance from a selected surface. There are two methods for determining the type of offset and
one to determine direction.
l (^) The default offset method behaves as if the selected surface were offset radially, so that a
surface with a 4-inch radius and a 1-inch offset would give a curvature on the end of the
extrude of a 3-inch radius.
l (^) The second method, called Translate Surface, behaves as if the surface were moved by the
offset distance.

Translate Surface options
l (^) Reverse Offset refers to when the offset stops short of the selected face or when it goes past it.
l (^) Up to Body. The Up to Body end condition is very useful in many situations, especially when
receiving the error message, “The end face cannot terminate the extrusion,” from the Up to
Face end condition.
l (^) Mid Plane. The Mid Plane end condition eliminates the Direction 2 options and divides the
extrude distance equally in both directions; for example, if you specify a 1.00-inch Mid
Plane, SolidWorks extrudes .50 inches in one direction and .50 inches in the other direction.
