## Overview

DrawingsManager is a Windows Forms companion for Tekla Structures drawings. Users refresh a drawing list, inspect status and marks, select model objects, produce BOM/revision details, and open drawings by assembly or part mark. The form also registers model-selection and change events. Drawing-type managers look up drawings and activate them through a shared base class. The excerpts support these main calls, but do not show the full event behavior or all UI actions; those connections are omitted where unverified.

Main entry points: [`DrawingsManager/DrawingManagerForm.cs`](https://github.com/razorcx/drawing-manager/blob/master/DrawingsManager/DrawingManagerForm.cs) (Drawing manager UI), [`DrawingsManager/SingleDrawingManager.cs`](https://github.com/razorcx/drawing-manager/blob/master/DrawingsManager/SingleDrawingManager.cs) (Single drawing access), [`DrawingsManager/AssemblyDrawingManager.cs`](https://github.com/razorcx/drawing-manager/blob/master/DrawingsManager/AssemblyDrawingManager.cs) (Assembly drawing access), [`DrawingsManager/DrawingManagerBase.cs`](https://github.com/razorcx/drawing-manager/blob/master/DrawingsManager/DrawingManagerBase.cs) (Drawing access base)
