Saving QY CAD documents to STL format
You can save QY CAD assembly, part, and sheet metal documents in Stereo Lithography (.stl) format. You can use the Export Options for STL (.stl) dialog box to control how the QY CAD document is saved in .stl format.
Exporting meshed bodies to STL
You can export part, sheet metal, and assembly files that contain meshed bodies to STL format. Use the options on the Export Options for STL (.stl) dialog box to define how you want to save the file.
Exporting assembly components
You can use the STL Document Structure options to export assembly components as:
-
Single STL document
-
STL document for each component
You can also use the StructureOption parameter SESTL.ini file to specify the STL document structure. Set the option to Monolithic to save the assembly components to a single STL file or to Shattered to save each assembly component to individual STL files.
When you set the option to STL document for each component, QY CAD creates a folder with assembly name and an STL file for each component in the assembly. For example, suppose you set the option to STL document for each component and save assembly_a that contains part_1, part_2, and part_3. QY CAD creates a folder named assembly_a that contains part_1.stl, part_2.stl, and part_3.stl.
Only design bodies are exported to STL format. Construction bodies and simplified data is not exported to STL format.
SESTL.ini file
The SESTL.ini file, found in the QY CAD 2022\Preferences\Translators folder, is used to store the settings defined on the STL Import Options and STL Export Options dialog boxes. When you make a change to a parameter in the dialog box, a new value is saved to the SESTL.ini file. You can use a text editor, such as notepad, to set these parameters. However, if you edit this file, use extreme caution in setting these parameters. Errors made to this file can adversely affect the quality of the translation. The following is a list of parameters found in the SESTL.ini file.
| Parameter | Description |
|---|---|
| Import Units | Stores the import units. The unit value can be Inch, Millimeter, or Meter. |
| Import Make Base Feature | Turns on or off the creation of a base feature. The default is on. |
| Export Units | Stores the export unit value. The unit value can be Inch or Millimeter. |
| Export Tolerance Type | Stores the tolerance type. The type value can be Custom, Fine, or Coarse |
| Export Tolerance Value | Stores the tolerance value. You must use a '.' as the delimiter. You can change the name by editing the value to the right of the equal (=) sign. |
| Export Surface Plane Angle Value | Stores the surface plane angle value in radians. You must use a '.' as the delimiter. You can change the name by editing the value to the right of the equal (=) sign. |
| Output File Format | Stores the output file format. The available values for the format are: 0=Binary, 1=ASCII. You can change the name by editing the value to the right of the equal (=) sign. |
| StructureOption | Specifies the structure of the exported STL document. The available values are Monolithic and Shattered. Setting the value to Monolithic creates a single STL for all assembly components, such as part files, weld files, and assembly features found in the assembly. Setting the value to Shattered creates a STL document for each component in the assembly, included any sub-assemblies. |
| Export Displayed Parts | Controls the inclusion of displayed parts in the exported file. The available values are Off and On. |
| Enable Logging | Turns on or off the creation of the log file. The default is on. |
