Curves DraftAnalysis/de

A sphere with a reflect line on its equator (left) and the related DraftAnalysis object (right)

1. Select one or more shapes.
2. There are several ways to invoke the tool:
   • Press the Draft Analysis button.
   • Select the Surfaces → Draft Analysis option from the menu.
3. A DraftAnalysis object is created for each selected shape.

• With this tool you can check if an object could be die cast in general and in connection with reflect lines determine the parting line for the die cavities, like in the above image. The tool direction runs through the poles of the sphere and its equator is the parting line. In this case the color sets above and below the parting line can be considered separate analyses of both halves.
• If this tool is applied to an object representing a die then one color set shows how well a cast item would detach from the die while the other color set highlights the regions that would obstruct the ejection of the item (undercuts).
• The angles should be set according to manufacturing process and material chosen for the selected item. For example:
  • AnsichtDraft Angle1+2: The minimum required angle that would still result in proper parts if other settings of the manufacturing process are fine-tuned and monitored.
  • AnsichtDraft Tol1+2: Added on top of the required angle giving the minimum recommended angle that will result in proper parts and a stable manufacturing process under any circumstance without further action.
• The colors:
  • AnsichtColor In Draft1+2: Marks areas with draft angles larger than the recommended angle.
  • AnsichtColor In Tolerance1+2: Marks areas with draft angles between the required angle and the minimum recommended angle.
  • AnsichtColor Out Of Draft1+2: Marks areas with draft angles below the required angle that can be interpreted as having no draft at all.

• AnsichtDirection (Vector): Anaysis direction
• AnsichtDraft Angle1 (FloatConstraint): Positive draft angle
• AnsichtDraft Angle2 (FloatConstraint): Negative draft angle
• AnsichtDraft Tol1 (FloatConstraint): Positive draft tolerance
• AnsichtDraft Tol2 (FloatConstraint): Negative draft tolerance
• AnsichtShading (FloatConstraint): Amount of shading on the analysis overlay

• AnsichtColor In Draft1 (Color): Color of the positive in-draft area
• AnsichtColor In Tolerance1 (Color): Color of the positive tolerance area
• AnsichtColor Out Of Draft1 (Color): Color of the positive out-of-draft area

• AnsichtColor In Draft2 (Color): Color of the negative in-draft area
• AnsichtColor In Tolerance2 (Color): Color of the negative tolerance area
• AnsichtColor Out Of Draft2 (Color): Color of the negative out-of-draft area

• DatenSource (Link): Object on which the analysis is performed
