Windows – Duplicating a shape in Microsoft Visio n times on the right with a specified horizontal spacing and at the same height

I found the following on a another site and it worked fantastic!
"Swimlanes have margins. Go to the "Cross-Functional Flowchart" tab, click margins, set to 0. You can then reduce the swimlane to any height you wish."

To remove all margins:

1. On the File tab, click Options, and then in the navigation pane, click Customize Ribbon.

2. In the Main Tabs pane, click to select the Developer check box, and then click OK.

3. On the Developer tab, click Show ShapeSheet, and then click Page.

4. In the Print Properties section of the ShapeSheet, set the following values to 0: PageLeftMargin; PageRightMargin; PageTopMargin; PageBottomMargin

   Otherwise, just set 0 to PageLeftMargin, and value PageLeftMargin for the rest i.e. PageRightMargin; PageTopMargin; PageBottomMargin

5. Use the Fit to Drawing command again. The page now resizes to fit the same dimensions of the drawing, and there is no margin.
