Surface / Curve > Combine Outlines (Trim Menu)

This command can be used to combine existing flat or linear objects to a single surface / curve. The outlines of all objects are simply included in one surface / curve.

The following object types are regarded as "flat": circle, circle sector, circle segment, ellipse, ellipse sector, ellipse segment, and surface.
The following object types are regarded as "linear": line, circle arc, ellipse arc, and curve.

The objects to be combined in one surface / curve are chosen. Click on objects to choose them.

The result in each case is one surface or curve object, which may however be made up of more than one surface part. A graphic showing examples of the combinations follows. The differently-colored hatchings show which areas are regarded as "part of the surface". All other areas are "outside the surface". This closes up any holes.

The areas of the objects shown hatched are hatched or filled if the relevant object is hatched or filled. The effects of this combination can be expressed as: ( Object 1 - Object 2 ) × ( Object 2 - Object 1 ).

If at least one of the chosen objects is "linear", the resulting object is a curve, otherwise, it is a surface.

The resulting object will contain all attributes of the chosen objects without duplicates.

This command works with all objects which have a closed outline. These are automatically converted to surfaces for the calculation. Many object types can not be converted into a surface without loss. The precision of the conversion can be specified using the command Drawing Settings > Precision in the entry "Transform". The original objects (which remain unchanged if the duplicate function is active), are not influenced by this conversion. Surfaces with "holes" can also be used.
