Linetype

Home

A linetype defines a line's characteristics. A line can consist of combinations of dashes, dots, spaces and symbols. New entities are added to a drawing using the current linetype. When you create a new drawing it already has linetypes named "ByLayer", "ByBlock", and, "Continuous".

These are the functions used to manage linetypes in a drawing:

Function	Meaning
lcDrwAddLinetype	Adds a new linetype into a drawing
lcDrwAddLinetypeF	Adds a new linetype into a drawing
lcDrwDeleteObject	Deletes an object from a drawing
lcDrwCountObjects	Counts a number of objects, by type
lcDrwSortObjects	Sorts objects by LC_PROP_TABLE_PRIORITY
lcDrwGetFirstObject lcDrwGetNextObject	Used to sequentially retrieve all objects
lcDrwGetObjectByName	Retrieves an object by its name
lcDrwGetObjectByID lcDrwGetObjectByIDH	Retrieves object by its identifier

Layer object has the following properties:
