Block > Create Block Creation Procedure, Insertion Point (Library Menu)

This command can be used to create a block creation procedure. After selecting the area to make up the block, an insertion point is entered.

You cannot directly create a block creating procedure with a polygonal section. If you require one, first use this command to create a block creation procedure with a rectangular section and all required settings, then call Manage > Procedures for Automation and use "Re-enter polygon" there to replace the rectangular section with a newly entered polygonal section.

The first corner point of the object selection area can be entered using the mouse, by clicking anywhere in the drawing. This corner point also shows the block's insertion point.

The object selection area's second corner point can be entered using the mouse, by clicking anywhere in the drawing.

The block's insertion point can be entered using the mouse, by clicking anywhere in the drawing. The insertion point should be placed at a distinct place in the block, e.g. at the end point of a line or the corner point of a rectangle.

After entering the insertion point, the "Create Block" dialog appears, in which the name of the block to be generated can be entered. In addition, some parameters can be specified.

Afterwards, the "Edit Procedure" dialog appears in which the name and parameters of the procedure are entered.

Blocks may themselves contain instances of other blocks and groups, i.e. nested instances are possible. This makes it possible, for example, to create components made up of components from several blocks from different libraries. There are however two restrictions, which should help avoid problems:
•        Internal blocks cannot be used in external blocks! This would make the block, and the whole library dependent on the drawing which contains the internal block.
•        The maximum number of levels which can be nested is 20. Deeper nesting is possible, but will not be displayed. If a circular reference is accidentally created (block X contains an instance of Y, block Y contains an instance of X), this is the same as an unending nesting and the blocks will not be displayed.
