How to do a draft angle analysis

The draft angle analysis of a 3d-model requires:

  1. the CAD data import into MODELS MENU or internally created CAD data using the CSG functionality,
  2. the selection of its material in the DOMAIN FEATURE and
  3. the creation of its Instance in the LAYOUT FEATURE.

Positive - on the casting part

Open the “Demolding” Menu from the MAIN FEATURES. To create a Parting Plane use “Add Parting Plane” or in the DEMOULDING MENU. Each parting plane can have three basic orientations: Horizontal, Vertical and Lateral - see the PARTING PLANE DIALOGUE on the right side of the screen. Select the orientation that best suits to the geometry by or in “Orientation” of the PARTING PLANE DIALOGUE. Press in the DEMOLDING MENU and set “Absolute Angles” to “True”. Click onto the “Plane Angle Mode” in the DEMOLDING MENU for the draft angle analysis. Fill in the Optimal, Functional and Marginal Angle in the DEMOLDING MENU, e.g. for permanent mold process:

AngleValueExample
Optimal15°gating system
Functionalcasting
Marginalcasting

Faces with angles below “Marginal” appear red. Faces with angles below “Functional” appear yellow. Faces with angles equal or higher then “Functional” appear pale green. Faces with angles equal or higher to “Optimal” appear full green. When you hold the right mouse button and hower of the faces of the part the local draft angle is shown.

Negative - on the mold

Open the DEMOLDING MENU in the MAIN FEATURES To create a Parting Plane click to the “Add Parting Plane” button or in the DEMOLDING MENU. Each parting plane can have three basic orientations: Horizontal, Vertical and Lateral. Select the orientation that best suits to the geometry by choosing the “Orientation” or in the the PARTING PLANE DIALOGUE. Press in the DEMOLDING MENU and set “Absolute Angles” to “True”.
