Geometry Menu

Crash has the following general geometry capabilities:
  • Import geometry from an external CAD file
  • Export geometry to an external CAD file
  • Create new geometry
  • Edit and defeature existing or imported geometry
  • Create connectors on geometry
  • Create loads/BCs on geometry
  • Create meshes on geometry
The following options are available from the Geometry menu:
Autocleanup Performs automatic geometry cleanup and prepares it for meshing based on the parameters set in the BatchMesher criteria file, which can be edited from this panel.
Card Editor Select the entities that are viewed in the card image subpanel.
Comparison Tool Perform a model-based CAD-CAD, CAD-FE or FE-FE comparison between two models, or two selections of entities. You can also use this tool to find and report on geometrical/shape differences.
Count Obtain a count of all the entities in your database.
Defeature Find and delete pinholes, fillets on surfaces and surface edges and duplicate surfaces.
Delete Delete data from a model database, preview and delete empty collectors and preview and delete unused property collectors, material collectors or curves.
Distance Determine the distance between two nodes/points or the angle between three nodes/points or to change distances or angles.
Edge Edit Modify surface edges.
Geom Match Topology Fix gaps between stitched edges and vertices to make the actual geometry of the surfaces consistent with the model topology.
Length Determine the length of a selected group of lines.
Line Edit Split, join or extend lines.
Lines Create lines using a wide variety of methods.
Mass Calc Obtain the mass, area and/or volume of a selected group of elements, solids or surfaces.
Metadata to CAE Take metadata generated as part of the CAD import process and use it to setup CAE models.
Midsurface Extract the midsurface representation of a solid part.
Nodes Create nodes using a wide variety of methods.
Node Edit Associate nodes to a point, line, or surface/solid face; move nodes along a surface; place a node at a point on a surface; remap a list of nodes to a line; or project nodes to an imaginary line passing through two nodes.
Normals Display the normal of an element or surface, adjust the orientation of element normals and reverse the normal of an element or surface.
Numbers Display the IDs of an entity.
Organize Reorganize your database by copying or moving data (entities) among collectors or includes.
Permute Switch coordinates of model entities in the global coordinate system.
Point Edit Perform many point-specific geometry cleanup tasks.
Points Create free points using a wide variety of methods.
Position Specify a new position for model entities.
Project Project data entities to a plane, vector, surface, or line.
Quick Edit Many tools for rapid editing of model geometry.
Reflect Reflect portions of a model about a plane, changing the selected portion into a mirror image of itself.
Renumber Renumber entities.
Rotate Rotate entities around an axis in space.
Scale Increase or decrease an entity’s dimensions.
Solid Edit Modify solid entities, including trimming and/or splitting solids and merging solids into a single entity.
Solids Create solid geometry using a wide variety of methods.
Surface Edit Allows you to perform a variety of surface editing, trimming and creation functions.
Surfaces Create surfaces using a wide variety of methods.
Systems Create rectangular, cylindrical and spherical coordinate systems.
Translate Move entities in a single specified direction.
Vectors Create a vector entity.
