Macro Automatic drawing

This code generates a Drawing page with three orthographic views (front, top and right) aligned to each other, and an isometric view placed at the top right of the page. It calculates the scale based on the model size and space available on the sheet. The iso view is scaled to 2/3 of the ortho views.

It uses the first-angle projection.

How to use
An object needs to be selected before launching the macro.

Limitations

 * Scale is not standard. You may need to change the views manually to a standard scale.
 * It only works with a single object (this is a limitation from the Drawing Workbench)
 * Needs to be modified to work for third-angle projection used in the US and Canada.
