Scale Transform

To produce a Scale Transform in the Main Menu select Operations - > Transformation - > Scale Transform

This operation creates a scaled shape basing on the initial shape.

Simple scale scales the entire object (i.e. its dimensions change evenly in all three orthogonal directions). It does not modify the geometry of the shape.

The following parameters and options can be defined in this dialog:

• Result Name;
• One or several Objects to be scaled;
• Central Point (optional) - relatively to which the object is scaled. If the Central Point is not defined, the scaling will be performed relatively the origin of the global coordinate system.
• Scale Factor - the multiplier of axial dimensions. If Scale Factor is negative, the object is mirrored through the Central Point.
• Advanced options.

TUI Command: geompy.MakeScaleTransform(Shape, CenterOfScale, Factor)
Arguments: Name + 1 shape(s) + 1 vertex + 1 Scale Factor.

Multiple scale allows scaling by different factors along axes. This is a general transformation, which can modify the geometry, for example, a circle can be transformed into an ellipse.

The following parameters and options can be defined in this dialog:

• Result Name;
• One or several Objects to be scaled;
• Central Point (optional) - relatively to which the object is scaled.
• Scale Factor X/Y/Z - the multipliers of axial dimensions.
• Advanced options.

TUI Command: geompy.MakeScaleAlongAxes(Shape, CenterOfScale, FactorX, FactorY, FactorZ)
Arguments: Name + 1 shape(s) + 1 vertex + 3 Scale Factors.

Example of simple scaling:

The initial object

The resulting object (resized)

Example of scaling by different factors along axes:

The initial object

The resulting object (resized and distorted)

Our TUI Scripts provide you with useful examples of the use of Scale Transformation and of Scale Along Axes Transformation
