In order to transfer most objects of the required type when setting the export parameters, the corresponding options must be enabled. Polygonal objects are exported unconditionally. |
Hidden solids and components are not written to STL format, they may be or may be not written to STEP, JT and C3D formats depending on the settings; they are written to other formats as visible, i.e. the "hide" attribute is not transferred.
Solids and components excluded from the calculation are not written to the target format, i.e. they are regarded as removed from the model.
When exporting sketches, two types of lines are transmitted: axial and main. Text, designations and construction lines of sketch are not transmitted.
|
Please take the following into consideration when exporting a model to STL. If the model contains polygonal objects, obtained by transformation of solids/surfaces, and the source solids/surfaces for these objects are kept in the model, to avoid data duplication, it is recommended to hide the source solids/surfaces before performing the export or disable the transfer of solids/surfaces when configuring export parameters. |
Type of resulting objects
•Solids, surfaces, and points are transferred without changing the object type.
•Curves are transferred as follows:
•lines, arcs, broken lines and splines are transferred without changing the object type,
•curves by law, isoparametric curves, spirals (cylindrical and conical), fillet curves and connections of curves are transformed into splines,
|
If the fillet curve is an arc, it is transferred without change. |
•equidistants are transformed into curves similar to the base curves. For example, if the base curve is a line segment, the equidistant is transformed into a line segment; if it is an arc, it is transformed into an arc; if it is a curved segment of a curve, it is transformed into a spline.
•Dimensions are conveyed as a set of 3D curves and texts.
•Design elements are transferred without changes (arrows, serifs, and base marks at the ends of leader-lines are not exported).
Other features
•ParaSolid XT
When exporting files, the standard schema file No. 10004 is used.
•STEP, C3D
In the final file following information is recorded:
•designations and names of the product and its components,
•information about the author and organization, as well as comments (the values of the corresponding properties are recorded by default)
The final file can contain the density value specified in the model (when exporting to all STEP and C3D formats) or the mass value (when exporting to STEP AP242 and C3D formats).
•Assembly components that have the same source can be converted into inserts during export, each of which has its own source. This occurs if it is not possible to obtain a model identical to the original in the target format by other means, for example, if inserts of the same component are assigned different colors in the assembly or if they are modified by an operation in the assembly (for example, a hole passing through several components is created in the assembly).
