The first two dimensions cannot be guaranteed in the styling. These two size values ​​can only be achieved by establishing the parameters and analyzing features, and setting the two size values ​​as optimization targets through the system automatic convergence calculation. Two optimization goals require two parameters, and the system can solve the unique solution. These two parameters are the angle of inclination of the bend line and the bend radius.
The third dimension is guaranteed when creating two "angle bend" features. The steps for creating these two features are as follows: the bending feature is bent at an angle of the inner radius, and the bending line is bent at a distance of 30 mm from the bending line of the deformation region to the center of the symmetry plane.
3. Establish analytical characteristics
Establishing analytical features is also about establishing optimization goals. Create a dialog window for analyzing features, as shown in Figure 4. Analysis features include the following types:
(1) The measurement includes the measurement distance, the angle between the side length and the like;
(2) The curve analysis includes curve analysis such as curvature, radius of curvature, and projection length;
(3) Model analysis includes model analysis of mass, centroid position, and moment of inertia;
(4) Surface analysis includes surface analysis such as Gaussian curvature, dihedral angle, normal vector, and radius of curvature;
(5) relationship;
(6) UDF is a user-defined feature.
This model only establishes two analysis features: HOLE-DIS-measures the center axis of two vertical wall circular holes parallel, the distance between them; ANALYSIS 1-measures the distance between the central axis of two vertical wall circular holes to the outside of the bottom plate.

The "optimization target" is evaluated within the entire parameter variation range, and the sensitivity analysis calculation dialog box is shown in FIG. 5. The parameter selection can be either a size or a parameter. Each size and parameter is given a range of variations in its value. Enter one or more defined "analytic features" in the "Parameters to be staked" field. Enter the number of segments in the "Steps" column for all parameters in the given "Value Range".
