Select Draft Angle
Selecting Draft Angle involves three options:
- Delta: The user can select the Draft Angle, Upper and Lower limits of tolerances.
- Eg., In the figure shown above, it means that any surface which has its orientation at 2.85 degrees to the pull direction, plus or minus two-tenths of a degree, will be green. The default tolerance is 0.2 tenths of a degree, and is balanced, meaning that it is applied equally in both directions (plus and minus). The value can be changed in an identical fashion to the Draft Angle as described above, with identical effects to the scale.
- Limit: Defines the Minimum Value and Maximum Value of draft angle extremes.
The user can select the desired draft angle to be used for analysis. The default Draft Angle is 2.00 degrees. The draft angle can be changed (increased/ decreased) in increments of tenths of a degree with the help of buttons, or by typing a value inside the text box.
Note: If a new value is selected for the Draft Angle, the scale below the parameter settings changes accordingly.
The coloring of the analysis will apply to any surface evaluated based on the draft angle and tolerances.
Min value: This is the lower boundary of the analysis, expressed in degrees of variation from the pull direction, and can be a positive number, negative number, or zero.
Max value: This is the upper boundary of the analysis, expressed in degrees of variation from the pull direction, and can be a positive number, negative number, or zero.
Note: There is no “tolerance” in this specification as there is in the basic mode.
Gradient: Selection of Gradient specifies a range of deviation from the pull direction, and have the analysis report the results. This option is useful where the effects of a compound surface or a set of surface transitions (such as seen in the blends of a boss with a sidewall and a floor of a pocket) need to be analyzed.
- Parting Line Visualization: Sets the analysis tolerance to zero. Any surface with non negative (zero or greater) draft will be green while surfaces with negative draft will be red. The partying line is represented by the transition between red and green. Also if there is any red surrounded by green, then there must be some tooling allowance made to accommodate it through the use of slides, lifters or core pins. No geometry is created representing the parting line.
Note: When Parting Line Visualization is selected, Gradient option will be grayed out.
Preview Bar displays the colors depending upon the value selected in the draft angle.
Note: To change the color scale double-click on the color component, this displays the dialog box. Choose the desired color and the scale will change accordingly.
