SolidWorks Reader

The SolidWorks Reader provides full access to the Assembly, B-rep, Visualization, View and PMI Data stored within a particular SolidWorks file. A file does not need to have a particular extension to be read correctly by HOOPS Exchange however the file extensions of SolidWorks files that you can expect to be loaded by HOOPS Exchange are:

  • .SLDASM
  • .SLDPRT

Our readers are updated to the latest released version within 90 days of the release of the authoring software. You can see the exact version supported in the current release here.

Assembly

Incremental load is supported by our SolidWorks reader. Full support for configurations is included.

B-rep

SolidWorks uses Parasolid as its geometry engine. As a result the reading of the B-rep in our SolidWorks reader is based on our Parasolid reader which allows you to query the full topological and geometric model defined in a Parasolid file. HOOPS Exchange provides evaluators which allow you to direct query all the geometry types available in Parasolid. You can additionally ask HOOPS Exchange to approximate any specific geometry and provide it in a standard NURBS form.

The list of surface types available in SolidWorks is:

  • Blend surface
  • B-spline surface
  • Cone
  • Cylinder
  • Offset surface
  • Plane
  • Sphere
  • Revolution surface
  • Swept surface
  • Torus

The list of curve types available in SolidWorks is:

  • B-spline
  • Circle
  • Ellipse
  • Intersection curve
  • Line
  • UV curve

Visualization

The SolidWorks reader can directly access the visualization data stored within a SolidWorks file. This occurs if the reading mode in HOOPS Exchange is set to tessellation only.

Views

Our reader supports Solidworks named views. Filtering is not supported.

PMI

HOOPS Exchange provides access to all PMI data available in a Solidworks model file (Reference and DimXpert annotations).\ The only exception is Stacked Balloon which is currently not available.

SolidWorks features support

Feature tree reading is supported with SolidWorks, with access to detailed information for holes, patterns and threads. Pitch, handedness and tip angle data are not retrieved for threads contained in holes.

When available the feature geometry association (faces) is supported.

Textures

The SolidWorks reader supports diffuse textures.

Miscellaneous

  • Units for files up to SLW 2007 are by default expressed in g/mm^3.
