Tutorial 19: Import SOLIDWORKS Part and Assemblies

How to prepare and import SOLIDWORKS Parts and Assemblies

We use the CAD-Line dialog-box | Solids tab to import SOLIDWORKS Part and Assembly documents.


Information-24

The correct Type-Library file must be in the MechDesigner installation directory before you can import documents from SOLIDWORKS.

In MD14 and later, the Type-Library installs automatically. If you install or use a different SOLIDWORKS release, you must restart MechDesigner.

To check that the Type-Library is correct for the SOLIDWORKS release you want to use: see Help menu > About > Type-Library tab.

Coordinate System in MechDesigner

This CAD-Line is automatically added with the Added-Part.

CAD-Lines:

Use CAD-Lines to import CAD Solids (SolidWorks, STL), and DXF files.

There is one CAD-Line along the center of each Added-Part.

To import more CAD Solids onto the same Part, edit the Part, and add to it more Cad-Lines.

ALL CAD-Lines have a Coordinate-System

Origin: start-Point of the CAD-Line

+X–axis: from start-Point to end-Point

+Y–axis: +90º (CCW) from +X–axis, on the Mechanism Plane

+Z–axis: perpendicular() to the Mechanism Plane.

COORDINATE-SYSTEM IN SOLIDWORKS

The image shows the SOLIDWORKS CAD document prepared with a Coordinate System.

To give me flexibility, I usually do these steps to add a Coordinate System to the SolidWorks model:

1.Add a new PlaneRed-14-1b

SOLIDWORKS > Insert menu > Reference Geometry > Reference Plane

It becomes the XY-Plane of the new Coordinate System. It will be coplanar with the Mechanism-Plane in MechDesigner.

2.Add a new SketchRed-14-2 to the new PlaneRed-14-1b

Add a two perpendicular(⊥) construction lines, with their intersection to coincide with the start-Point of the CAD-Line.

Close the sketch.

The lines become the +X-axis and +Y–axis of the Coordinate System.

The intersection of the lines becomes the Origin of the Coordinate System.

The perpendicular(⊥) to the -XY-Plane becomes the +Z–axis of the Coordinate System - using the Right-Hand Rule for Coordinate Systems.

3.Add the Coordinate SystemRed-14-3  

SOLIDWORKS > Insert menu > Reference Geometry > Coordinate System

a.Click the point at the intersection of the construction lines as the Origin

b.Click the construction line that is the +X-axis

c.Click the construction line that is the +Y–axis.

The +Z–axis automatically becomes normal to the Plane defined by the +X and +Y–axes and the Right-Hand-Rule.

The +Z–axis is towards you, the same direction as the +Z–axis direction of the CAD-Line in MechDesigner.


Note: Alternatively, you can also select from the model, a:

a Surface as the Plane

a Vertex or Center-Point as the Origin

an Edge as the X-axis

However, I prefer to add a new Plane and Sketch to locate the Coordinate System.
