When I copy a picture from ChemDraw 3.0 and paste it into my word processor, there is an additional white space around the structure which I cannot seem to get rid of.
A border of white space exists around all objects that are selected within a Selection rectangle. When you copy objects to the Clipboard this white space border is also copied. In ChemDraw 3.0, the width of the white space border is controlled by the tolerance setting in the Preferences dialog box. However, the tolerance setting is not scaled when you magnify or reduce your view, resulting in a larger white space border at reduced views (such as Show Page) and a smaller white space border at magnified views. For example, at actual size (100%) a tolerance setting of 5 pixels represents a 5% white space border in proportion to the selected objects. If you reduce your view to 50%, this same 5 pixel white space border increases to 10% in proportion to the selected objects.
Update to the latest version of ChemDraw. In the latest version, the white space border is now scaled when you magnify or reduce your view.
NOTE: As a temporary solution until you receive your update, if you select objects in a reduced view, be sure and magnify your view to actual size or greater (if memory allows) before choosing the Copy command. The resulting white space border becomes smaller in proportion to the selected objects as you magnify your view.
