**1.Contour Boundary**

Contour Boundary is used to control the path of generating top lines and toe kick lines in the front-end tools. It needs to be called and edited in the Elements.

**2.Submodel Calling**

In cabinet modeling under the model library, all panels must be called from the submodel library, and it is not allowed to edit using flat panels from the Elements.

**3.Dimension Range at Corners**

For parameter W1, its dimension range must be carefully considered. The maximum value of W1 must not exceed any possible values of W. There are two ways to solve this issue. (The same applies to D1).

a. Express the maximum value of parameter W1 as a constant, which is smaller than the value set for the minimum value of parameter W.

b. Express the maximum value of parameter W1 as a formula, for example: #W-100.

(Now, we will demonstrate using method b)
