Import

When reading a file, the result is converted into a common data model that provides format-neutral data representation and access API.

Supported Formats

Manufacturing Toolkit can import STEP (.stp/.step) and native MTK (.mtk) format models.

Reading files

ModelData_ModelReader is the primary class for reading files. The usage is simple: one just has to call a single function with the path to the file that should be read and the target ModelData_Model instance.

The data model object will be populated with the contents imported from the file being read. The model is not cleaned up before conversion, therefore multiple files can be accumulated in the same model.

import manufacturingtoolkit.CadExMTK as mtk
 
aModel = mtk.ModelData_Model()
aReader = mtk.ModelData_ModelReader()
if not aReader.Read(mtk.UTF16String("myfile.stp"), aModel):
    #error during reading the file

Parameters

Reader parameters are controlled by ModelData_ModelReaderParameters class and can be set using ModelData_ModelReader.SetParameters() method.

Parameter	Default value
ModelData_ModelReaderParameters.ReadPMI()	`false`
ModelData_ModelReaderParameters.ReadDrawing()	`false`
ModelData_ModelReaderParameters.EnableAnalyticalRecognition()	`true`

Export

To export a model, use the Save() method provided by the ModelData_Model class. This method writes the contents of the model to a file in the specified format. Supported formats are defined in the ModelData_Model.FileFormatType enum.

Supported Export Formats:

.mtk
.mtkweb

ModelData_Model aModel;

// Populate the model...

if not theModel.Save("output_model.mtk", mtk.ModelData_Model.FileFormatType_MTK):

print("\nERROR: Failed to export")
