Unite

See also: Unite: local operation.

Menu access: Shape | Unite

Description:

Allows you to unite a shape with other shapes.

General philosophy:

  1. Select the shape(s) to modify.

  2. Select the shape(s) to unite with.

Available option(s):

You can apply union locally by using only some faces of the tool or the shape to modify with the  LOCAL OPERATION  button.

The  Hide tools= YES  or  NO  option allows you to set the subtracted shape invisible or not after the subtraction.

The  Follow= SUBSEQUENT OPERATIONS  or  EXISTING OPERATIONS  allows you to make the union evolve or not after its creation if you modify afterward the tools (addition or subtraction of operations such as pocket, drilling...)

 You can enter a radius in order to compute a fillet on the intersection edges of the operation.

Specific point(s):

 If you have different surfaces representing a close volume (they have common boundaries), you will use the sewing function (Shape | Other Operation | Sew) on them to get a solid shape. If you use the unite function, the result will still be a closed surface.

 If you design a part by creating half or portion of it and you want to complete it using a duplication (Shape | Duplicate) and union (Shape | Unite), it is better to directly use the Shape | Other operations | Pattern function.
