# Data Exchange

Data exchange is used for data sharing of different types of files, either by importing files from other applications into the CrownCAD software or by exporting multiple format models for use by other applications. The interface for importing outside the project, inside the project and inside the document is shown in the figure below:

# Import

The imported files include parts, assembly, engineering drawings, pictures and videos, and the format is supported

Standard version:

.igs, .iges, .stp, .step,Catia(.catproduct, .catpart), ParaSolid(.x_t), SolidWorks(.sldasm, .sldprt,) NX(.prt), PTC(.asm, .prt),.stl, .obj,.dwg, .dxf, .pdf, .zip, .rar, .png, .jpg, .jpeg, .bmp, .gif, .mp4, .svlx

Pro Edition:

.igs, .iges, .stp, .step, Catia(.catproduct, .catpart), ParaSolid（.x_t, .x_b), SolidWorks(.sldasm, .sldprt, .slddrw),SolidEdge( .par), NX(.prt),Inventor(.iam, .ipt) PTC(.asm, .prt,.drw), .stl, .obj, .ifc,.cgr,3dm,.3dxml,.rvm, .jt, .sat, .rvt, .dwg, .dxf, .zip, .rar, .pdf, .png,.jpg, .jpeg, .bmp, .gif, .mp4, .svlx, ppt(.ppt, .pptx), word(.doc, .docx),Emp,emn,vda

Tips to use:

1）Import up to 10 files at a time, optionally compressed into a zip.

2）For Standard Edition users, the maximum number of uploads per day is 10, and a maximum of 20M documents can be uploaded at one time.

3）The file name can be Chinese, English or numeric symbols;

4）Import a large file, which may take a long time.

# Import Setting

Click System Settings - System Options - Import to go to Import Settings where you can set the import formats.

Click Import - Import file command and click Import Settings on the Import interface to also enter the Settings dialog box.

# File Format - General

【Ignore Hidden elements】 : Controls whether to read hidden entities/surfaces/curves in the assembly file.

【Read curves】 : Controls whether to read curves.

【Read the original model file thumbnail】 : Control whether to read the original model file saved in the thumbnail, support SolidWorks/CATIA/NX format.

【Read point】 : Control whether to read the point.This feature supports reading spatial points from Creo, UG, CATIA, and SolidWorks models. These points are then imported as 'datum points'.

【Hide datum】 : Controls whether the datum of the imported model is displayed or hidden by default.

【Stitch mesh】 : Select stitch to do as a whole import, there is only one mesh in the feature panel; Without stitching, the grid is imported in blocks, and each grid in the feature panel is regarded as a grid.

【Read constraint】 : Controls whether to import the assembly fit relationship, which may affect the conversion efficiency.

【Document name source】 : A file in the format of CATIA. The component name recorded in the file may be different from the file name. When importing such files in CC, it is supported to read the part name information recorded in the file, and you can choose to use "file name" or "part name recorded in the file" as the name of the part document after import.

【Retain file name extension】 : When the document name source is "file name", control whether to retain the file name extension.

【Resolution】 : Set the precision of the imported model, only for non-grid class models.

# File Format - NX

[Engineering drawing] : When importing NX file, the engineering drawing in the file is read by default.

# Import Interface

Click the import-Import file command to bring up the Import dialog box:

You can drag the file to the dialog box, or click Upload, specify the file path and filter the file format, click Import after upload, start the upload and conversion operation, the process can be viewed in [Task].

# Assembly Import

  1. Multiple file assembly model, you can package all model files into a zip file, and make the zip file name consistent with the top assembly file name, the default conversion of the top assembly after uploading.

  2. If the assembly is inconsistent at level 2, the user needs to manually select the document that needs to be converted.

  3. When importing an assembly in intermediate format, the option "Do you want to merge the assembly?" will be prompted:

  1. The missing parts in the import assembly can be specified manually by right-clicking the menu:
  • Right-click a missing part in the feature panel to choose to specify the part or remove it.

  • Select the specified part from the menu and the "Specify Part" dialog box will pop up.

    • If there is a document with the same name as the missing part within the current project, the part or assembly with the same name within the current project is selected by default.
    • If there is no part with the same name, the part or assembly of the current project is displayed by default. If the missing part is an assembly, the assembly of the current project is displayed by default.

  • The "Show Preview" function makes the preview of the selected part appear in the location of the missing part in the viewport. This item is not checked by default.

  • Select the part and click OK. The missing part will be replaced by the selected part.

# Drawing Import

Support to read NX, SolidWorks, Creo, CATIA drawings.

  1. When uploading prt file, add "include NX file engineering drawing" option, if checked, convert, if not checked, do not convert; Checked is only valid for the current Settings, and the conversion is performed according to the Settings in "Import Settings" by default.

  1. List of tasks:
  • When uploading: Only one record appears in the task list;
  • During and after conversion: Display two records "xxx.prt" and "XXX.prT.DWG";

    • The "Cancel button" can be used to cancel the conversion model or engineering drawing respectively;
    • After successful conversion, you can use the open button to jump to the corresponding model or project drawing respectively;
    • If there is no project drawing in the prt file, and the user has checked the project drawing, the pop-up prompt "No dwg read". The engineering drawing task status displays "Not read".
  1. Creo drawings must be uploaded at the same time as the drawings and the 3D model file they reference in order to convert correctly, it is recommended to package the file as a compressed package and upload it.

# Folder Import

For files that need to be converted in batches, you can directly upload the folder, and the system will import all files in the folder. For unsupported formats, the system will prompt "This type of file is not supported" when opening.
