Version 0.9.9m - 11.21.2018
- Added the stair module (straight run only) with the following advanced options: thrust block, landing tread, hanger board.
Hanger Board and Landing Tread:

Landing Tread:

There are quite a few options with the stair module so I will need to make another tutorial video explaining the usage of these parameters. I have provided tool tips next to each option in the draw and edit menus to help explain what each is.
A few items with the draw tool:
1.) First select the top of the stairs location and then select a point for the bottom of the stairs. The preview wireframe should be fairly explanatory as to the location and geometry of the stairs that will be created.
2.) Once the first point is selected you can lock to an orthogonal axis (0, 45, 90, 135 deg.) or direction by repeatedly clicking the "Ctrl" key.
3.) Once the first point is selected you can also toggle the placement of the stairs by repeatedly clicking the down arrow. The justification is: Center, Left, or Right.
4.) As with the other HTML draw menus, you update/change your parameters and then click the Update button to make them live. You can leave the menu open while drawing your stairs. Hitting the space bar will exit the tool, hitting the ESC key will reset the tool.
With the draw and edit menus you will notice that for the tread and riser material you also have the option of utilizing materials found in your custom library. The stringer material is limited to certain specific material types (at least for now).
This is a completely new module so I expect there may be some minor issues and additional features that will be requested.
I still need to create the global settings tab for the stairs so that default parameters can be set for each option. However, it is not critical to the function of the module.
