Adding Model Dimensions to a Parametric Fitting
Use this procedure to add dimensions to specify the overall default size of the model.
TIP You may find it easier to add model dimensions in the top view, rather than in a model view direction. To
change the view, click View tab
1 To define the overall length of the trunk, in the part browser, right-click Model Dimensions,
and then 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.
2 Select the trunk modifier feature in the modeling area, and specify a location to place the
dimension.
A length dimension (LenB1) is placed in the model and is added to Model Parameters and Size
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.
3 To define the overall length of the branch, in the part browser, right-click Model Dimensions
and click Add Distance.
4 Select the branch modifier feature in the modeling area, and specify a location to place the
dimension.
