The solution to this question requires the use of Dimension Favorites and some preparation (SolidWorks 2007).
Open any drawing that has dimensions. Go to Tools pulldown>Options>Document Properties tab> and select Arrows in the left pane. This will bring up the window with several sections related to Arrow sizes. In the Size section, change the dimensions of the arrow as desired. Pick (left-mouse-button click) OK. This will change the drawingÆs arrow size globally.
Pick any dimension on the drawing. The Dimension Properties pane will appear in the Feature Manager area. SolidWorks has a Favorites section for each dimension. This appears at the top of the Dimension Properties pane. Pick Add or Update a Favorite button. Enter a name in the corresponding window that appears and pick OK. (Note: special characters may not work in Favorite names.)
Pick the Save a Favorite button. This brings up a file save window. Enter a file name and pick Save. This has now saved the Dimension Favorite for future use by any drawing. Now quit the drawing (do not save the drawing).
Open up the drawing where the new Dimension Favorite is required. Pick the dimension(s) that will use the new Dimension Favorite. In the Favorites section, pick the Load a Favorite button. Find and pick the desired Dimension Favorite file and pick Open. The Dimension Favorite will now be applied to the chosen dimensions.
