Once you have selected a SmartTemplate, you can begin building using the Forms SmartPanel. There are actually two different Forms SmartPanels. The blank form SmartTemplate has a special Form Design SmartPanel because it takes different tools to build a form than to modify a form.
If you chose the blank form, you will need to add form blocks to it. Click on a block in the Add Shapes Symbol Gallery found in SmartPanel, then click again in the Work Area where you would like to add it. Tip: if you let your cursor hover over a symbol for a few seconds, the full title of it will pop up.
