The following table compares the supported features provided by ModelerGeometry and Spatial 3D ACIS® Modeler.
| Modeler's Feature | ModelerGeometry (ModelerGeometry.tx) | Spatial 3D ACIS Modeler (SpaModeler.tx) |
|---|---|---|
| Render the model in wireframe, shaded, and silhouette mode | Supported | Supported |
| Get the extents of the model | Supported | Supported |
| Use PHLR, a view-dependent representation that consists of visible and hidden curves of input objects (getHlrCurves()) | Not Supported | Supported |
| Explode into a set of OdDbEntity objects | Supported | Supported |
| Create simple shapes (box, frustum, sphere, torus, wedge, pyramid) | Supported | Supported |
| Extrude a planar curve, region, or planar surface in the direction of the given vector, with many advanced options controlled by OdDbSweepOptions (createExtrudedObject(), extrude()) | Partially Supported (Not supported: the taper option and the extrusion of an angled entity) | Supported |
| Extrude a region along a path curve (extrudeAlongPath()) | Supported (Limitations: the taper angle must be zero, the path must be a smooth curve or polyline perpendicular to the region plane at the path base point, and both path endpoints must not lay on the region plane or must be equal) | Supported |
| Revolve a specified curve, region, or planar surface around the specified axis of revolution (createRevolvedObject(), revolve()) | Partially Supported (Not supported: non-solid creation, axis is not in contour's plane, and mostly all OdDbRevolveOptions) | Supported |
| Sweep a face along the specified path (createSweptObject()) | Partially Supported (Not supported: history mode, non-zero taper angle, non-zero draft distances, non-zero align angle, align mode other than kAlignSweepEntityToPath, disabled checkIntersections flag, twist reference vector other than identity) | Supported |
| Create a tangent surface between two edges of a surface with constant radius (createFilletSurface()) | Not Supported | Supported |
| Create a lofted object from the given curves (createLoftedObject()) | Not Supported | Supported |
| Perform Boolean operations (booleanOper()) | Partially Supported (Currently the functionality works as a Protocol Extension and is disabled by default) | Supported |
| Set up attributes (colors, materials, etc.) | Supported | Supported |
| Get area, centroid, moment of inertia, product of inertia, principal moments, principle axes, radii of gyration | Not Supported | Supported |
| Get perimeter | Supported | Supported |
| Get the intersection between the specified plane and the model (OdDb3dSolid::getSection()) | Not Supported | Supported |
| Slice the model with a plane and transform the object to be the portion remaining on the positive side of the normal of the slicing plane (OdDb3dSolid::getSlice()) | Not Supported | Supported |
| Offset all faces by the specified distance (offsetBody()) | Not Supported | Supported |
| Separate the model into an array of solids representing the additional disjoint volumes (separateBody()) | Not Supported | Supported |
| Find the intersection with another model (intersectWith()) | Not Supported | Supported |
| Get the triangle mesh of the model with the required triangulation parameters (getObjectMesh()) | Supported | Supported |
| Sculpture operation — creating a waterproof solid from a set of objects (createSculptedSolid()) | Partially Supported (Currently the functionality works as a Protocol Extension and it's disabled by default) | Partially Supported through the use of ModelerGeometry (Currently the functionality works as a Protocol Extension and it's disabled by default) |
| Displaying solid history | Supported | Supported |
