Yes there is a default coordinate system. It's listed in the feature tree right after the default planes as "Origin" Y is up. As far as I know, coordinates imported from a text file or spread sheet will use this origin by default.
Thanks for the reply. Sorry in the delay in responding.
SolidWorks will give me this message: "A table pattern needs a coordinate system to define its transformaions."
I can't select the 'Origin' you mentioned above. Did I miss something here?
From the help menu.
You can define a coordinate system for a part or assembly. Use this coordinate system with the Measure and Mass Properties tools, and for exporting SolidWorks documents to IGES, STL, ACIS, STEP, Parasolid, VRML, and VDA.
To create a coordinate system:
Click Coordinate System on the Reference Geometry toolbar, or click Insert, Reference Geometry, Coordinate System.
Use the Coordinate System PropertyManager to create the coordinate system.
You can amend your selections:
To change your selections, right-click in the graphics area and select Clear Selections.
To reverse the direction of an axis, click its Reverse Axis Direction button in the PropertyManager.
Click OK .
To the best of my knowledge, you have to create a coordinate system to use the Table Driven Pattern. Yes, SW does have a default coordinate system. If you use the "coordinate system" tool as Tony details above, you can then just create a coordinate system, and not change any of the parameters. It will create a coordinate system based on the default axes.
Thanks, Tony and Charles. I guess Charles summed it up well: we DO have to create the coordinate system. I know how to create one, I was thinking that perhaps I can simply select something somewhere ...
