	Pointwise can import the solid model and exploit the information it contains about how the surfaces are stitched together. Even when using native CAD files, it is a good idea to check to see if the solid model is watertight. This is carried out in the Create, Assemble, Models panel by selecting the model and clicking Assemble. If the solid model is watertight, there should be a single model (all surfaces green) and zero lamina boundaries (red edges). If the solid model is not watertight, the tolerance can be increased to automatically close the gaps.

			=Reorganize Surfaces=
			Quite often the arrangement of the surfaces created by the CAD software is not optimal for meshing. For example, the body of the filter tube is made up of four surfaces, but we probably only need one surface mesh patch to represent the whole tube. The complementary capability to Pointwise's solid modeling is quilting. Quilting allows the user to redefine the meshing regions from the original CAD surfaces to something more meaningful. In the filter tube example, we want Pointwise to create one surface mesh patch on all four filter tube surfaces. This is accomplished by quilting the four surfaces into one logical meshing region. By not requiring the grid boundaries to follow all the CAD topology, we end up with a simpler grid topology and higher mesh quality.

			The quilt assembly feature has the ability to automatically assemble the quilts based on an angle criterion. The angle is defined as angular deviation between the normals of the adjacent surfaces.

added check integrity

	The model size tolerance is an important consideration when importing CAD files into Pointwise. We recommend adjusting the model size tolerance to within about an order of magnitude of the largest spatial dimension of the geometry. This parameter is found in the File menu under Properties. Setting the appropriate model size tolerance helps Pointwise's geometry kernel interpret and process the geometric information with the highest possible degree of accuracy. In order to maintain maximum integrity, this step must be performed prior to importing the geometry. If you do not know the actual model size, import the geometry using the default model size tolerance, record the value from the File, Properties panel, undo the import, set the appropriate model size tolerance and re-import the CAD file.

			=Check Integrity of Solid Model=
			Pointwise can import the solid model and exploit the information it contains about how the surfaces are stitched together. Even when using native CAD files, it is a good idea to check to see if the solid model is watertight. This is carried out in the Create, Assemble, Models panel by selecting the model and clicking Assemble. If the solid model is watertight, there should be a single model (all surfaces green) and zero lamina boundaries (red edges). If the solid model is not watertight, the tolerance can be increased to automatically close the gaps.
