Assembly
Summary of available functionality for defining the properties and behavior of parts in the model.
- Materials
- Rigid Parts
  A rigid part can displace under the loading, but only as a rigid body, i.e. without deformation or strain.
- Spots
  A Spots is a feature that enable applying loads, constraints, or other boundary conditions (BC) to local regions on the surface, instead of applying BC to the whole faces of the model
- Create Coordinate System
  Define a local coordinate system to which boundary conditions may be later applied.
- Import Coordinate System
  Import coordinate system from an external comma separated values (CSV) file. Multiple coordinates can be imported at once.
- Create Line on Part
  Create a line that can later be used to generate seam welds.
- Create Sheets
  Create a sheet from an imported surface by applying thickness.
- Create Laminates
  Create laminate from an imported skin
- Set Part Type as Bolt
  Define parts as bolts.
- Set Part Type as Protruded
  Define parts as protruded.
- Replace Part
  Replace a part in an existing assembly with an alternative design.
- Set Orthotropic Material Geometry
  Define the material orientation of the part.
- Create Datum Plane
  Create a Datum plane to use them as a clipping plane or to review the results along a cut-section.
- Import Datum Points from CSV
  Import datum point sets from an external comma separated values (CSV) file.
- Create Liquid Body
  Create a liquid body between selected faces.
- Create Gas Body
  Create gas body between selected faces.
- Assembly Review
  You can clean up the geometry in your model by removing undesired parts.
  - Assembly Info
    This dialog provides summary information for all parts in a given Project Tree branch.
  - Review Parts
    Rank/find parts, including seam welds, based on volume or relative volume, and suppress or delete parts.
  - Review Similar Parts
    Find groups of similar parts that have the same geometry in different positions.
  - Show Parts by ID or Name
    Locate parts in the assembly by their ID or name.
  - Check Geometry Defects
    Check the quality of part facets.
  - Check Part Overlaps
    Identify overlapping parts in the model.
  - Find Part Self Intersections
    Identify parts that contain overlapping edges.
  - Compare Assemblies
    Show geometry differences between two design studies on a part-by-part basis.
  - Create Local Studies
    Create local design studies linked to global studies.
Connections
Connections are used to define the association of different regions of interest between parts in an assembly.
Create Analysis
Create an analysis for your project.
Boundary Conditions
Boundary Conditions available for SimSolid.
Post Processing
Run analyses and view a variety of results in SimSolid.
Design Study
Design studies allow you to quickly evaluate and compare the structural performance from different design scenarios.
Verification Problems
Solved verification models.

Find Part Self Intersections

Identify parts that contain overlapping edges.

In the Project Tree, open the Assembly workbench.
In the Assembly workbench toolbar, click Check geometry defects.
Click the Find part self intersections tab.
In the modeling window, select the parts of the model you want to check.
Click Find.
All part self intersection are identified. Parts with self-intersections are marked in red, sheets with thickness smaller or bigger than nominal are marked in orange, and parts with no defects are marked in green.
Click Repair sheets to remove any self-intersections.
Optionally, thick and thin areas can also be repaired to have uniform nominal thickness for the entire part. This process is iterative; you can repair sheets and rerun the Find and then Repair sheets options until all issues are resolved.
Optional: You can click Undo repair to remove any repairs done by SimSolid.
Click OK.
