Part CheckGeometry/pt-br

Description

The Part CheckGeometry command runs a verification and reports if geometry is a valid solid. The command checks if the Boundary representation (BRep or B-rep) of the model is valid.

Usage

1. Select a part (beware to select the whole part and not just a face to check for valid solid)
2. There are several ways to invoke the command:
   • Press the Check Geometry button.
   • Select the Part → Check Geometry option from the menu.
3. The Settings task panel opens, unless Skip settings page is enabled. See Options for more information. Click Run check.

Results will be reported in the Task panel. If the check produced errors: click in the report on a specific error message and the corresponding geometric object (edge, face, etc.) will be highlighted in the 3D view.

Options

Skip settings page

If ticked, subsequent invocations of the command skip showing the Settings task panel.

Run boolean operation check

If ticked, additionally a Boolean OPerations (BOP) check is performed.

Single-threaded

Run the geometry check in a single thread. This is slower, but more stable.

Log errors

If ticked, any errors found are also logged in the report view.

Expand shape Content

In addition to detecting potential geometry errors, this command shows a range of properties regarding the selected object:

• Checked object
• Shape type
• Number of geometric entities: vertices, edges, wires, faces, shells, solids, compsolids, compounds, total shapes
• Geometric and mass properties:
  • Area
  • Volume
  • Mass
  • Length
  • Center of mass
  • Orientation
  • Symmetry axis
  • Symmetry point
  • Moments
  • First axis of inertia
  • Second axis of inertia
  • Third axis of inertia
  • Radius of gyration
  • Global placement

Advanced shape content

Show advanced shape content. Changes will take effect next time you use the check geometry command.

Individual boolean operation checks

The user can choose the type of boolean operation to be checked:

• Bad type
• Self-intersect
• Too small edge
• Nonrecoverable face
• Continuity
• Incompatibility of face
• Incompatibility of vertex
• Incompatibility of edge
• Invalid curve on surface

Notes

• App Link objects linked to the appropriate object types and App Part containers with the appropriate visible objects inside can also be checked using this command. For App Links the shape of the linked object is checked. For App Part containers the visible objects within are checked as compounds. introduced in 0.20
• FreeCAD has no methods to automatically repair geometry. If faults are detected the steps involved to create the model need to be examined and fixed manually.
