Save the model to a new file-name.

The CXL and MTD files save at the same time. These are the MechDesigner 'native' files.


Save the model that is in the active Mechanism-Editor to the LXL file-type.

This is a Library File.

Library File Restrictions

The restriction of the LXL file-type are, are:

it is a model on one Mechanism-Editor
it cannot have any 'child' Mechanism-Editors
it cannot have any 'child' Planes

When you attempt to save a Mechanism-Editor to a file of the LXL file-type, then, if it has 'children', the file will NOT be saved.

This pop-up will show. Click the OK-tiny-13-17 to close the pop-up..



The ZXL file-type compresses all files: CXL, MTD, STL, STLPRT, and DXF files; into one one file with the ZXL file extension.

Important: the model needs a CXL file-name before you can save the model to a ZXL with the same file-name.

If the model does not have a file-name, then do

1.File menu > Save as... to the CXL file-type BEFORE
2.File menu > Save as... to the ZXL file-type.

Use the same file-name for the ZXL.

If there are STL files in the model, and you want to also save the original SolidWorks SLDPRT and SLDASM documents to the ZXL file:

1.Exit SolidWorks BEFORE
2.File menu > Save as... to the ZXL file-type.


You can use WinZip® or 7Zip®  to unzip the ZXL file.


To save a DXF of the Mechanism-Editor or a Part, then do:

1.Click a Mechanism element or a Part element in the Assembly-Tree.

The Mechanism or Part element must show in the Selection-Window.

2.Click File menu > Save as...
3.Select the DXF as the file-type in the Save As... dialog
