About Setting the Size of a Drawing View
You can set the size of a drawing view so that when you change dimensions of the model, the size of the drawing view stays constant relative to a given model dimension. To do this, specify the model parameter drawing_scale_factor, used in Drawing mode as a view scale factor. This parameter is a scale factor that the drawing scale multiplies to determine the actual size of the entire drawing view.
 
* This does not change the value of "d#" in the drawing or the overall drawing scale, only the spatial dimension of the displayed entities.
The following table shows how the system calculates the size of the drawing view using the drawing scale and the drawing_scale_factor model parameter.

Changing drawing scale. Drawing scale changed to 2; the edge length in the view becomes 10.

Initial conditions.
Model edge has a corresponding dimension d# = 5. If the drawing scale is 1 and the edge length is 5, the "drawing_scale_factor" is set to 1.

Changing dimension value.
Value of d# changed to 10 in Part or Assembly mode, so "drawing_scale _factor" becomes .5. Makes the calculated length in the view half of its dimension value (it remains 5 (unchanged)).

Changing value of "length" parameter.
Value of "length" parameter changed in the relation to 10, so "drawing_scale_factor" becomes 2. Multiplies the length of the edges in the view by 2.

Changing value of "length" parameter at a given scale.
The edge with the dimension value of 5 appears in the drawing with a scale of 2. Changing "length" parameter to 10 changes "drawing_scale_factor" to 2, so the calculated length of the edge in the drawing is 20.
