3. The
Mechanical Layout/Design
|
|
|
|
|
|
|
|
|
|
|
|
A) Parametric
Solid… |
|
|
|
|
|
|
|
|
|
|
|
|
This
is the most complex type of solid model and most
versatile. Great
for a family of parts because all or most of
the dimensional can be controlled from a
spreadsheet. Example, A square has four lines
two sets of
parallel line, and the corners are at 90
degrees. These constraints
are maintained regardless of the length of the
line. The part is then extruded to a certain
height, and by setting the length of the
extrusion equal to the side of the square a cube
will be generated having properties like mass,
volume, center of gravity……. Or the length
of the extrusion could be maintained at 2 times
the side and a model to generate a block that
would be basically two equal cube
stacked. The two dimensions (length of lines)
can then be put into a spreadsheet and when a
new part is needed the spreadsheet can add
another part of a different length and a new
detail drawing can be generated without
really drawing the part again.
The actual drawing showing the
dimensional data for machine is generated. |
|
|
|
|
|
B)
Boolean solid….. |
|
|
|
|
|
|
|
|
|
|
|
|
This
is the least complex type of solid model. Great
for conceptual work because the time to
constrain and tie to a spreadsheet is
all but eliminated.
Still yields mechanical properties of mass,
volume, center of gravity…. Example…
draw a square, extrude to height required
or extrude along a path. This would result in
multiple parameters in a parametric model. |
|
|
|
|
|
C)
Flat
two dimensional mechanical layout
|
|
|
|
|
|
|
|
|
This
is best used for simple piece part drawing. The
results of a parametric or Boolean solid model
will yield two dimensional drawings also but are
automatically updated when the solid is changed
and can generate isometric views. |
