SFH = 18
SID = 144
SRS = 300
SRZ1 = 8
SRZ2 = 70
SSTh = 12
SVPC = 192
These constants can be changed later to variables, lists, ranges, or tables
for further part customization. Keep the Model Parameters dialog box
open for the next step.
7 Next, you'll change each of the work plane offset parameters (WPOf1
through WPOf5) to correspond with a structure parameter. For example,
instead of the first offset being approximately 12", it now corresponds
with the SFH parameter. So if you later adjust the SFH parameter, the
work plane offset (and its plane geometry, profiles and dimensions) will
adjust accordingly.
Select WPOf1, and then select Calculator. The Equation Assistant dialog
box is displayed.
8 Select the Variable button to use the pull down to select which structure
parameter should match this work plane offset. Click SFH. Press OK to
exit the Equation Assistant dialog box. The SFH parameter is displayed
under the Equation column in the Model Parameters dialog box.
9 Repeat the previous two steps for each work plane offset parameter using
the following values:
WPOf2 = SRZ1
WPOf3 = SCH
WPOf4 = SRZ2
WPOf5 = SBSH
Remain in the Model Parameters dialog box for the next step. The
following parameters are displayed under the equation column in the
Model Parameters dialog box:
WPOf1 8.0000
