Chapter 4: Creating Simple Parts, Assemblies, and Drawings


Extruding from a selection


The From panel establishes where the Extrude feature starts. By default, SolidWorks extrudes from the
sketch plane. Other available options include:

l Surface/Face/Plane. The extrude begins from a surface body, a face of a solid, or a reference
plane.

Extruding from a surface

Cross-Reference


Surface features are discussed in detail in Chapter 27. n

l Vertex. The distance from the sketch plane to the selected vertex is treated as an offset distance.
l Offset. You can enter an explicit offset distance, and you can change the direction of the offset.

Direction 1 and Direction 2


Direction 1 and Direction 2 are always opposite one another. Direction 2 becomes inactive if you
select Mid Plane for the end condition of Direction 1. The arrows that display in the graphics window
show a single arrow for Direction 1 and a double arrow for Direction 2. For the Blind end condition,
which is described next, dragging the arrows determines the distance of the extrude.

Each of the end conditions is affected by the Reverse Direction toggle. This toggle simply
changes the default direction by 180 degrees. You need to be careful when using this fea-
ture, particularly when using the Up to end conditions, because if the entity that you are
extruding up to is not in the selected direction, an error results.
Following is a brief description of each of the available end conditions for the Extrude feature:


l Blind. Blind in this case means an explicit distance. The term is usually used in conjunction
with holes of a specific depth, although here it is associated with a boss rather than a hole.
l Up to Vertex. In effect, Up to Vertex works just like the Blind end condition, except that the
distance is parametrically controlled by a model vertex or sketch point.
