This section provides reference information that is intended to help you:
create Prismatic Machining Area features from your design part
use Prismatic Machining Area features:
for formulas, checks and tool queries in machining
processes and machining operations (for example, to find the appropriate
tool to machine the machining area)
for search queries
For more information, refer to Feature Attributes for Tool Queries, Checks and Formula.
The following Prismatic Machining Area features are supported:
Islands can be included Pocket and Step type machinable features.
Note: When running Feature Recognition, the milling areas (with non-planar
top element) are taken into account for feature creation (Prismatic
Machining Area). Prior to V5R18, conditional checking was done on top and
bottom face. These conditions are now replaced by stringent condition checking
on bottom face only, whereas conditions are not applied on top face.
The top face can be any surface, it does not need to be planar which
is parallel to bottom face.
Feature recognition provides a Prismatic Machining Area corresponding
to a Complex Pocket. The boundary is defined by a hard boundary
only. An imaginary contour at the intersection of Hole and Slot is
automatically defined to close the hard contour.
| A complex pocket is a closed multi-sided
recess.

Specifications on part: A bottom stamp as a hard stamp A top element as a top limit A boundary comprising a series of ordered faces. Results in Prismatic
Machining Area: |
| A complex step is an open multi-sided recess.
|
Specifications on part: A bottom stamp as a hard stamp A top element as a top limit A boundary comprising a series of ordered faces with hard and soft qualifications. Results in Prismatic Machining Area: |
| A through slot is a specific step whose
contour is two parallel faces as a hard boundary and two other faces as
limits.
|
Specifications on part: A bottom stamp as a hard stamp A top element as a top limit A boundary comprising a series of 4 ordered faces with hard and soft qualifications. Results in Prismatic Machining Area: |
| A blind slot is a specific step with two
parallel lines and a corner between them. It has an open boundary.
|
Specifications on part: A bottom stamp as a hard stamp A top element as a top limit A boundary comprising a series of 4 ordered faces with hard and soft qualifications. Results in Prismatic Machining Area: |
| A complex cutout is a multi-sided opening
through the part.
|
Specifications on part: A bottom element as a bottom limit A top element as a top limit A boundary comprising a series of ordered faces. Results in Prismatic
Machining Area: |
Islands can be recognized and associated to Pocket and Step type machinable features. Islands can be associated to features without necessarily sharing a bottom face. See examples below:
Specifications on part:
A bottom stamp as a hard stamp
A top element as a top limit
A boundary comprising a series of ordered faces.
Results in Prismatic Machining Area:
A depth from top to bottom
A top plane and a bottom plane
A wireframe contour.
