Working With DuctDesigner 3D
Q: When I create an Air Handler I get arrows showing connection direction, but the AHU doesn't display on the Symbols tab. Why?
A: After you have drawn a Symbol and established the connection, you can add it to the Symbol library by executing the DuctDesigner 3D > Create Symbol > Make Symbol command. The Make Symbol topic in the DuctDesigner3D Online Help file gives detailed instructions for making a symbol.
After you have completed the Make Symbol procedure, the unit displays on the Symbols tab, and is available for additional applications.
Q: I have a client who does not use DuctDesigner3D and can't view my 3D entities. Why?
A: AutoCAD and DuctDesigner3D use proxy graphics. In order for your clients to view these graphics, you must make sure the proxy graphics settings are turned on in AutoCAD before sending the drawing to your client.
To correct the problem perform ALL of these steps:
- From the AutoCAD or ADT Tools or Format menu, choose Options > Open & Save. Under Show proxy images select Show proxy graphics.
- At the Command line, type PROXYGRAPHICS confirm or enter a value of 1.
- At the Command line, type PROXYSHOW and confirm or enter a value of 1.
Q: While working in DD3D I've found that panning and zooming take 4 to 5 times longer than usual. Why?
A: AutoCAD treats 3D Wireframe in the same way it handles full-blown shading. To correct the problem, check to be sure you are in 2D Wireframe rather than 3D Wireframe.
To check the setting, type SHADEMODE at the command line. The AutoCAD response will display the Current mode. To change the Current mode, enter 2D at the command line.
Tip: If your UCS icon appears as 3D colored arrows, you are not in 2D Wireframe.
