Adding Model Dimensions to a Parametric Junction Box MvPart
Use this procedure to add dimensions to specify the length, width, and depth of the junction box.
TIP To avoid distortion of the model, add the overall model dimensions first, and then add the individual dimensions
for the geometry.
1 To define the overall height of the junction box, in the part browser, right-click Model
2 In the modeling area, select the junction box modifier feature and specify a location to place
3 To specify the actual height of the junction box, in the part browser, expand Model Parameters,

The Model Parameters dialog is displayed.
NOTE Creating a modifier with a plane termination type enables you to use the distance between
work planes as the defined length of the modifier feature. In this procedure, you use the distance
between the work planes you created when adding the lip as the height dimension for the lip.
If you need to change the value, double-click Equation for WPOf2, and enter a number to change
the value.
Dimensions and click Add Distance.
NOTE For constant parameter values, you can define a constant dimension, or choose not to add a
dimension and use the default value based on the actual size of the geometry. When no dimensions
are added, the parameter and its value are not displayed during part size selection.
the dimension.
A height dimension (LenB1) is placed in the model and is added to Model Parameters in the
part browser. The value of LenB1 is a default value based on the extrusion distance of the feature,
and it can be changed.
right-click LenB1, and click Edit.
