Advanced options for program control.

3D Boolean operations

Transfer material from operand on its facet: When checked, material from one object is transferred onto the other during a 3D boolean operation (3D add, 3D subtract, etc.). When unchecked, the materials are not affected on either object.

Miscellaneous settings

Nudge Step: Sets the distance that a nudge will move an object. Values are specified in Pixels.

Zoom factor: Controls how much you zoom in or out of the drawing when you use View / Zoom In or Zoom Out. The default zoom step setting is 2, meaning that zooming in doubles the size. See Zoom In and Zoom Out.

Zoom In/Out Centralize: When this feature is On (default), rolling the mouse wheel will zoom in/out and centralize the view & cursor at the center of the drawing area. When this is Off, rolling the wheel will zoom in/out at the location of the cursor.

Fixed relative origin: If checked, the relative origin will be fixed while in relative or polar coordinates. If you need to relocate the origin, it must be done manually. See Relative Coordinates and Polar Coordinates.

Geometric select edit: If checked, objects will be selected by their geometric extents, rather than their cosmetic extents. This permits geometrically accurate scaling of objects like double lines and lines that have nonzero width. See Geometric and Cosmetic Select Modes?.

Apply general property changes to all tools presets: Enables the Property toolbar to change all styles for all tools.

Intelligent Scale

Hatch: When a hatch is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom.

Text: When a text is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom.

Dimension: When a dimension is created it is automatically scaled to an appropriate size relative to the current view. This means in particular to the level of zoom.

Custom Coefficient: This is a scaling multiple that is applied to the intelligent scaling. For example 2 would double the size whereas 0.5 would halve the size.
