The Cadimage Doors+Windows tool includes a number of inbuilt door panel styles. However, if you want to design something a little more interesting, you can create a Custom Door Leaf.
First, use slabs to draw the door leaf in plan view. Remember to set pens, materials and section attributes as you want them to appear when converted to a door leaf.
Select the fills, and from the File menu choose Libraries and Objects > Save Custom Component.
A dialog will come up listing all the component types you can create. Choose Cusom Door Leaf. In the next dialog choose a name and save the component into the Embedded Library.
In the Cadimage Door Settings dialog, set the Leaf Type to Custom.
Choose the new Custom Door Leaf from the list.
The new leaf will be inserted into the frame.
