File.dxfThe DXF file format was developed by AutoDesk in the early days of AutoCAD- their, then, flagship product. It is a neutral, Drawing eXchange Format that captures twodimensional data in a vector-based file (in contrast to a bit-mapped image file such as JPEG). The important aspects of a vector file are accuracy and scalability. AutoDesk publishes the DXF Specification so that other CAD vendors can support it within their products. No matter what CAD product you use, you can easily export a DXF file representation of your gasket for use in the Rapid Gasket Ordering System.
Layers are a label used within the DXF file to further tag objects, such as line and circles, with additional information. The Rapid Gasket System requires ALL edges of the gasket- internal, external, bolt holes, etc.- be identified with one, unique Layer that is given a unique Layer Name. This is easy to do and once done the Rapid Gasket Ordering System can process your DXF file, automatically.
The customer can control the material condition separately for External and Internal edges thereby insuring the best combination of form, fit and function. The inside of a gasket is typically exposed to a different environment than the outside and we want our customers to have the ability to optimize their gasket design.
There can be none, one or multiple internal edges in a gasket which is represented as a 2- dimensional object (the customer adds the thickness separately from the drawing). The customer has three choices when it comes to cutting non-straight edges of the gasket (arcs, circles, ellipses, etc.). These choices are: Maximum material condition, Minimum material condition and Best-fit. It is easiest to show by illustration what each choice means when applied to the internal edges of a gasket.
There is only one, continuous external edge in a gasket which is represented as a 2- dimensional object (the customer adds the thickness separately from the drawing). The customer has three choices when it comes to cutting non-straight edges of the gasket (arcs, circles, ellipses, etc.). These choices are: Maximum material condition, Minimum material condition and Best-fit. It is easiest to show by illustration what each choice means when applied to the external edge of a gasket.
The picture below shows Maximum Material Condition for External and Internal Edges. The blue dashed line represents the gasket as drawn and the solid line represents the gasket as it will be cut. Maximum Material Condition means there will always be excess material after the cutting process. Use this setting when you want to be sure there is enough gasket material for the seal and when the excess material will not interfere with appearance and mating parts. The amount of excess material is controlled by the Tolerance parameter.
The picture below shows Minimum Material Condition for External and Internal Edges. The blue dashed line represents the gasket as drawn and the solid line represents the gasket as it will be cut. Minimum Material Condition means there will never be excess material after the cutting process. Use this setting when you are sure there is enough gasket material for the seal and when you do not want excess material to interfere with appearance and mating parts. The amount of subtracted material is controlled by the Tolerance parameter.
The picture below shows Best-Fit Condition for External and Internal Edges. The blue dashed line represents the gasket as drawn and the solid line represents the gasket as it will be cut. Best-Fit Condition means the the amount of excess material is equal to the amount of subtracted material after the cutting process. Use this setting when you are sure there is enough gasket material for the seal and when you want to average excess and subtracted material. The amount of excess/subtracted material is controlled by the Tolerance parameter.
