Analyze a Part Model

Targets of Model Analysis

Checking geometry:

• The program analyzes the status of sketch constraints and reports under- or over-definitions of a sketch.
• Note that Vertex G4 does not force you to design sketches that are fully defined with constraints. In particular, sketches of dimensional variable models (such as those used in product automation systems) should be fully defined.
• The program also analyzes the flawlessness of the Acis geometry of the configurations in the model.

Checking configurations:

• The analysis prints the number of configurations and the names of the configurations in the model.

Model drawings:

• The analysis prints the number of drawings and the names of the drawings of the model.

Dimension variables:

• The analysis prints the dimension variables in the model, including the dimension variables in the model features.
• You can also see the dimension variables in the model by hovering over the main symbol in the feature tree.

Version number:

• The analysis tells you which version the model was originally designed with.
• Note: If the model was designed with a version older than 15.0.00 (released in September 2008), the program will not find such information from the model, so it will give a blank answer.

Model properties:

• The analysis tells whether the part is shown in the assembly parts list or assembly drawing, how the part symmetry is defined (this is relevant if the part is mirrored in the assembly), whether the part reference geometry (guide lines and auxiliary planes) is shown in the assembly drawing and how part machining is allowed in the assembly (when the machining features in the other parts are used for machining) or, if the part is transparent, whether it is shown in the assembly drawing.
• The context-sensitive Properties function opens a dialog where you can change the properties.

Item data:

• The analysis tells you the label and description of the model item or the lack of an item.

Mass calculation:

• Analyzes the part volume, mass and center of gravity location, and moments of inertia with respect to center of gravity.
• You can get the same information with the Mass function.
• You can affect the density that significantly affects the mass with the context-sensitive function Item Data, which describes the name of the material item or material used.

Draft accuracy:

• Analyzes the drawing resolution used by the program (tolerance or angle tolerance and reports the number of surface triangles). The analysis also tells you if the default tolerances for the Acis modeler are in use, or some other values.
• Note that the number of surface triangles is only told if the drawing resolution has been changed first.
• You can adjust the drawing resolution on the View tab by using the Draft Accuracy function in the Settings group.

Named elements:

• The analysis tells you the named elements used in the model, if any have been added to the model.
• The most commonly named element is the grip point that controls the placement of the components. After selecting a point, you can add a grip point with the context-sensitive Add Handle function.
• You can add, delete, and edit named elements with the context-sensitive Other Functions > Edit Named Elements function.

Part area:

• Analyzes the area of the part. This is the "painting area" of the part and not, for example, the area of ​​the sheet metal required for the sheet metal part.

Number or elements by type:

• The analysis tells the types and numbers of the geometric elements of the part.
• This information tells to how much computer resources the part requires.
• The information can be useful when wondering about the strange behavior of imported parts; planar surfaces are spline surfaces, in which case it is not possible to assign distance constraints to them.
• You can change the planar-like spline surfaces of the imported parts to planar surfaces with the context-sensitive function ACIS Geometry > Heal and then with the Simplification Settings.
