File description:
Open C API interface to the sketcher.
The sketch functions in this file enable you to:
. Create an empty sketch. 创建一个空草图。
. Initialize (activate) and terminate (deactivate) an existing sketch. 初始化(活动)和退出(不活动)一个现有草图。
. Add/Extract geometric objects to a sketch. 添加/选取几何对象到指定草图。
. Mirror geometries.
. Create, query and delete dimensions and geometric constraints.
. Update a sketch.
. Interrogate a sketch including its orientation, origin, solved status,...,etc.
. Query constraint's type and constraints associated with a geometry.
. Query the type and status of a sketch dimension.
. Get all the geometries, expressions, dimensions, and geometric constraints for a sketch.
. Get all sketches associated with a face or a feature.
. Get all features associated with a sketch.
. Query/Edit current sketch preference settings.
