Issue:
User reported that after inserting a mesh file or converting the mesh body to a solid B-Rep, the performance in Fusion slows down.
- When using the Convert command to convert a Mesh Body to a B-Rep, one of the following messages may appear:
- Mesh to BRep conversion
Warning: This mesh contains many facets. Proceeding will result in slow performance.
Mesh surface content:
Facets = #
Conversion is not recommended.
- 1 warning(s)
This mesh has more than 10000 Triangles.
Calculation will take a considerable amount of time.
- When using the Convert command to convert a Mesh Body to a T-spline, the following message may appear:
- Mesh to T-splines conversion
Warning: This body contains a high percentage of triangles or n-sided polygons. Converting will likely result in a T-spline that will result in poor editing with slow performance. For best results the input mesh should consist of primarily four sided faces.
Mesh surface content:
Quads = XXXXX
Triangles = XXXXX
Polygons = XXXXX
Conversion is not recommended.
Mesh surface content:
Quads = XXXXX
Triangles = XXXXX
Polygons = XXXXX
Conversion is not recommended.
Causes:
- The mesh body contains too many elements.
- The mesh body contains the wrong type of elements for the requested conversion.
- Note: Mesh conversion is a resource-intensive process.
- Currently, a ceiling of 10,000 elements is the upper limit for successful conversion.
- Conversion occurring on machine with too little memory will experience a reduction in performance after conversion.
Solution:
Too many elements
If the mesh body contains too many elements, modify the mesh body to reduce the number of elements in the mesh.
- If the mesh body contains more than 10,000 facets, the conversion process may continue to fail.
- Use the tools from the modify menu to reduce the count of mesh facets.
Use Prismatic Conversion Method
Use the Prismatic method to convert multiple mesh faces in each face group into one solid model face. See: Fusion Help: Convert a mesh body to a solid body
This will reduce the total number of faces in the solid body created and may improve performance.
Wrong type of elements
If the mesh body contains the wrong type of elements (quads, triangles, or polygons), you may need to open the mesh file in the originating program and change the output settings for the mesh file.
