You calculate the coordinates of the cam profile with a CamData FB.
You can calculate the cam profile as a series of Points and with BiArcs.
To export the cam profile data to SOLIDWORKS from MechDesigner as a series of Points 
Open a CamData dialogbox: 1.Calculate the CamCoordinates at Equal increments of the Master Machine Angle  say 360 for a typical plate size of cam, 2.Make sure the SolidWorks is open, and a Part, existing or new, is the active document. 3.Click the send Cam Data to SolidWorks button. The data in SolidWorks is a Curve feature. 

The Curve feature is on the XYPlane, which is the Front View in SOLIDWORKS. Note: To move the Curve feature to the XZ or the YZ Plane. In the CamCoordinated dialogbox: 1.Save the Data as a TXT filetype 2.Edit the data in Excel®, and swap the Xdata, or Ydata, with the Zdata 3.Save the data to NotePad® In SOLIDWORKS: 4.Click Insert menu > Curve > Curve Through XYZ Points 5.Import the data, and close the Curve feature dialog 6.Select a Plane that is coplanar or parallel to the Curve feature 7.Start a sketch on the Plane 8.Use Convert Entities in SolidWorks® sketch editor 9.Extrude the Curve. You can see the Cam does not have any facets. 

1.Open the file, with filetype as... *.TXT 2.Select delimiter, as a ',' or 'tab'. You want the 'X' and 'Y' Cam Points in separate columns. Experiment with the import options if necessary. 3.Tidy up the data, remove headers etc. 4.Move all the data so the first X Point starts at Cell A1, and the first Y Point at B1. 5.Add a Column for the ZAxis, and fill it with Zeros (0). 6.If necessary, make the first and last point to be identical. Experiment as necessary. Some CAD will close the cam for you, other CAD will not. 7.If necessary, scale the CamData to the units you are working in your CAD 8.Save your data as an Excel® spreadsheet, for backup purposes. 9.Save your Data to a NotePad® file. You will use the file that you save in Excel® or NotePad® to import into your CAD. 
Insert Object / Curve by TableSelect: 1.Surfacing tab → Curves group → Keypoint → Curve By Table 2.On the Insert Object dialogbox, set the Create from File option and click OK. Browse to and Open your Excel® spreadsheet Curve by Table uses an Excel spreadsheet to define a construction curve. The spreadsheet, which is embedded in the Solid Edge document, allows you to more easily import your data. Solid Edge: Curve by Table Parameters dialog
Curve by Table ParametersCurve Fit •Linear Segment Creates line segments between the data points in the table. •Smoothing Off Applies the direct curve fit method to the data points in the table. Using this method, the curve passes directly through the points. •Smoothing On Applies the 'least squares' curve fit method to the data points in the table. Selecting this option enables the tolerance drop list. Using this method, the curve path is controlled by the tolerance value and does need to touch the points. •Tolerance Allows you to specify a tolerance for the Smoothing On option. Gives the maximum distance the curve can deviate from the points. Curve End Conditions •Open Allows you to specify an open curve. For example, the first and last data points do not touch each other or any part of the curve. •Closed Specifies a closed curve. For example, the first and last data points can touch one another or any part of the curve. When this option is set, the Periodic and Natural options become available. •Periodic Connects the first data point with the last data point to make a smooth tangent closed curve. •Natural Creates a closed curve without a tangency condition. Note: The 'Curve by Table' Feature will fail if the first and last data points in the spreadsheet are coincident. If you select 'Closed', delete the last point in the table that is coincident with the first. Coordinate System Allows you to select coordinate systems to offset the curve data to. Make the coordinate system prior to creating the curve through table of points. Numberofpoints Records the total numberofpoints in spreadsheet. Possible Problems with Curve by TableThe following are possible error messages resulting from Curve by Table: •Invalid Geometry: Edit Feature Inputs The data points in the spreadsheet are incorrect. Check the spreadsheet and make certain you have input at least two rows of X,Y,Z coordinates, have not skipped any cells, and have not entered data points that define a curve that runs back through itself either in 2D or 3D. •Curve Is Self Intersecting The curve runs back through itself in 2D or 3D. Change the data points in the spreadsheet. •Units Set Out Of Range The units are too large. Make sure the diameter of the model is less than five kilometers. •Curve By Table Feature Failed Closed and Periodic options are set on the Curve Table Parameters dialogbox, and the first and last data points in the spreadsheet are coincident. Change one of the coincident data points.
