In addition, once all the parts have been combined together, redundant grouping and hierarchy nodes will be deleted or merged. In general this option only makes sense to enable when the "Method to Import BREP Solids Objects" combo box is set to "Bodies, shells and Faces" since this import method will create a huge number of "Face" objects. For this importer it is not recommended that you need to enable this option. These options will implicitly import the least number of object parts.

The "Help" button which appears on the dialog box when this button is pressed describes the object and hierarchy compression algorithm further.

People who create 3D models in a modeling package will do so using a specific units system, such as meters or feet. However, when these models are imported into another 3D package that uses a different default units system such as Lightwave which uses centimeters , a "units conversion" operation needs to occur the imported model geometry needs to be rescaled.

This option determines what will be done when the units defined in the source file do not match current internal program system units.

If the units do not match, the importer will rescale the imported geometry based on the ratio between the source file units and the internal system units. It defaults to meters. What you need to do is select an appropriate entry from the drop-down combo box which matches the system units used by your destination program: for example, set it to Centimeters for Lightwave, Inches for 3DS MAX, Centimeters for Maya, etc this should be automatic if importing into 3ds max or Maya.

None No units; never do any geometry scaling Custom Custom units are in effect. See below Microinches 1e-6 inches Mils 1e-3 inches Inches 0. If the drop-down combo box is set to "Custom", then this edit text control defines the "units per meter" scale factor for the custom unit system. Vertex Normals. If this checkbox is enabled then the import converter will compute proper vertex normals for each triangle vertex. Vertex normals are necessary to make an object appear to be smooth when rendered.

Vertex u,v Texture Coordinates. If this checkbox is enabled then the import converter will compute proper texture u,v coordinates for each triangle vertex. Texture coordinates are necessary if a bitmap texture image is to be applied to the object at some time in the future.

If this checkbox is enabled then the import converter will remove any duplicated or redundant vertex coordinates. This will not modify the object but it may reduce the amount of memory required to store the imported model. Likewise, if this checkbox is enabled then the import converter will remove any duplicated or redundant vertex normals.

Likewise, if this checkbox is enabled then the import converter will remove any duplicated or redundant vertex texture coordinates. If this checkbox is enabled then additional rendering material attributes will be imported, if and only if they exist within the source data and are made available to this importer. Some of these attributes may include:. If this checkbox is enabled then lights will be imported, if and only if they exist within the source data and are made available to this importer.

Point, spot, directional and ambient lights are supported. Do not remove intermediate. If this option is enabled which is not the default then this intermediate temporary file will not be deleted from the Windows TEMP directory. An important aspect of this import converter is its surface tessellator.

The surface tessellator used in this import converter is the one provided by Spatial Technology. It converts the implicit surfaces to n-sided polygons, quads or triangles by applying the following refinement criteria, from highest to lowest: 1. Minimum number of U and V grid lines 2. Maximum edge length 3. Normal deviation 4. Surface deviation 5. Grid aspect ratio. Recommended Usage Method To make a bumpy or curved surface look smoother, move the 'Surface Deviation' slider more to the left.

To make rounded edges or a curved surface look smoother, move the 'Normal Deviation' slider more to the left. To make 'quad-like' polygons and not a pure triangular mesh, with many of the resulting polygons have a squarish aspect ratio: Change the 'Polygon Type' combo box to Triangles on fringes only. This slider specifies the maximum deviation in degrees between the normals on two adjacent faces. Various projection modes to take a look at model from its left, right, top, bottom, and isometric views are available.

You can choose from various background options, and can also view a model in Wireframe, solid, and solid with edges modes. Component tree of a model can also be viewed here. As I said, its a very simple viewer, and you will not find options here, other than the viewing tools I mentioned. EnSuite-View is a very good free Catia viewer, where you can view Catia 6 files, Catia 5 files, and Catia 4 files for free.

This software is a free version and comes with certain limitations. The limitations do not apply to the viewing tools, but applies to the number of files one can open here.

For the free version, you can only view 6 CAD files per month. You will have to sign in to the application first, before you can open Catia files here. Lets get to know about the viewing tools it has to offer. The design and engineering processes for complex buildings and infrastructures project development requires close collaboration among multiple stakeholders and across all project phases. CATIA allows architects, engineers, owners and governments to build and collaborate beyond the limits of traditional project delivery methods, by delivering a range of 3D modeling and As products and experiences continue to increase in complexity, performance and quality targets are becoming more demanding.

CATIA answers that challenge, enabling the rapid development of high-quality mechanical products. Mechanical engineers equipped with CATIA 3D Modeling tools can gain insight into key factors of quality and performance early in the product development phase. Digital prototyping, combined with digital analysis and simulation, allows product development teams to virtually create and analyze a mechanical product in its operating environment.

Developing smart products has never been more challenging. What are the curve to fit distance tolerances in Alias. The Curve Fit Distance is the tolerance to which trim boundaries are rebuilt to or approximated. This Curve Fit Distance setting should normally be accurate. This setting enhances the success of post transfer processes, such as skinning, that are to be carried out once the geometry is in CATIA. Whether you are creating a model, verifying a model, or debugging a translation, there are a number of tools in Alias you can use to check the quality of the geometry you have created.
