Tutorials
Start using Inspire Studio with our interactive tutorials.
Sketching
Create and edit a 2D sketch curve. A sketch curve is any "wire" entity such as a line, rectangle, circle, or arc.
Curves
Create and edit 3D curves by extending, rebuilding, intersecting, splitting, and projecting the shapes.
Surfaces
Create and edit 3D surfaces and solids by creating primitives or editing existing curves and surfaces.
PolyNURBS
Create polygonal surfaces that can easily be converted into NURBS surfaces.
- Primitives
  Create the basic shape of a PolyNURBS model.
- Edit
  Modify the shape of a PolyNURBS object.
  - PolyNURBS Edit Mode
    Double-click a PolyNURBS object to enter edit mode. You can then use Nurbify to visualize the object as a NURBS surface or polymesh, and edit the vertices, edges, or faces to modify the shape.
  - Create
    Create a PolyNURBS face, create a PolyNURBS surface from a polyline, or extract a polyline from an existing NURBS or PolyNURBS object.
  - Clean Up Invalid Geometry
    After merging faces and welding vertices, you may need to auto-correct invalid geometry by detecting and collapsing microscopic edges and faces.
  - Close Hole
    Close a hole in a PolyNURBS by creating a new face to fill the void.
  - Circle Maker
    Make a selected open loop of edges circular.
  - Split
    Split an edge, split a face, or add an edge loop.
  - Merge
    Merge faces or PolyNURBS objects.
  - NURBS to Poly
    Convert PolyNURBS objects into polymeshes. You can then save the polymesh as a STL file and send it directly to a 3D printer.
  - Subdivision Surface
    Refine and smooth a PolyNURBS surface by adjusting the parameters of its subdivisions.
  - Group Extract
    Automatically color-code the selection groups of a PolyNURBS object.
  - Wrap
    Use the Wrap tool to quickly wrap a PolyNURBS solid around a shape. You can create multiple PolyNURBS cages, and bridge the face of one cage to another.
  - Fit
    Create a PolyNURBS surface on top of an existing mesh. This is useful for quickly turning a complex structural optimization results into PolyNURBS surfaces.
  - Simplify
    Reduce the number of triangles in a mesh.
  - Fix Geometry
    Identify geometry issues, clean up invalid geometry, collapse tiny edges and tiny faces, and remove spikes.
  - Convert a PolyNURBS to a Trimesh
    Convert a PolyNURBS object into a triangular mesh.
Modify
Create new objects by manipulating and modifying source objects.
Direct
Quickly modify objects that are not a part of Construction History.
Deform
Deform one or more objects with respect to an axis.
Analysis
Analyze curves and surfaces, import simulation data, or access the Design Table and Variable Manager.
Dimensions
Dimension a line, edge, bounding box, angle, and radius/diameter in order to create objects which must fit predefined dimensions.
Drawing
Create detailed 2D drawings of the selected parts of a complex 3D model from multiple perspectives.
Rendering
Adjust the materials, environment, and properties of objects in the scene to create a photorealistic image.
Animation
In Inspire Studio you can animate an object or group and the camera. There are two methods of animation: key frame animation and path animation.
Die Design
Create a draw die in Inspire Studio that you can export to Inspire Form to perform a stamping simulation.
Custom Plug-ins and Scripts
You can use C++ and Python to add custom operations and file formats.
Keyboard Shortcuts and Mouse Controls
Learn keyboard shortcuts and mouse controls for common operations.
SpaceMouse Support
Inspire Studio supports 3Dconnexion's SpaceMouse.

Clean Up Invalid Geometry

After merging faces and welding vertices, you may need to auto-correct invalid geometry by detecting and collapsing microscopic edges and faces.

Press A, S, or D to open the Edit PolyNURBS tool panel.
Right-click in the edit PolyNURBS mode and select Clean Up .

Note: If no invalid geometry is detected, no changes will occur.
Right-click and mouse through the check mark to exit, or double-right-click.
