Hi, Michael.

Thank you very much for your answer, I have successfully solved this problem. But I also want to add ICONS to the command bar to DIY my moi 3d, which I think is very cool and practical. I'm going to add 2 ICONS here for import and export, as shown. I only know that I need to edit the SidePane.htm file, but I don't understand programming. I have tried several times and failed. Please help me, thank you very much.

Hi c3g, yes to add buttons there you will need to edit SidePane.htm, and locate the section for "SubDTabContent" which looks like this:

                    <div id="SubDTabContent">
					    <table style="width:100%">
						    <tr>
								<td><moi:CommandMenuButton icon="icons/SubDCreateIcon.png" menu="SubDCreateMenu.htm"><moi:Text textid="SubD create menu button"/></moi:CommandMenuButton></td>
								<td><moi:CommandButton style="visibility:hidden;">&nbsp;</moi:CommandButton></td>
								<td><moi:CommandButton style="visibility:hidden;">&nbsp;</moi:CommandButton></td>
								<td><moi:CommandButton style="visibility:hidden;">&nbsp;</moi:CommandButton></td>
				 		    </tr>
					    </table>
                    </div>

Edit it to be like this and place 64x64 pixel image files "STEPIn.png" and "STEPOut.png" inside the ui\icons folder:

					<div id="SubDTabContent">
						<table style="width:100%">
							<tr>
								<td><moi:CommandMenuButton icon="icons/SubDCreateIcon.png" menu="SubDCreateMenu.htm"><moi:Text textid="SubD create menu button" /></moi:CommandMenuButton></td>
								<td><moi:CommandButton icon="icons/STEPIn.png" onclick="moi.geometryDatabase.open('e:\\test.step');">STEP In</moi:CommandButton></td>
								<td><moi:CommandButton icon="icons/STEPOut.png" onclick="moi.geometryDatabase.saveAs('e:\\test.step');">STEP Out</moi:CommandButton></td>
								<td><moi:CommandButton style="visibility:hidden;">&nbsp;</moi:CommandButton></td>
							</tr>
						</table>
					</div>
