## Overview

Tekla Properties is a Windows dialog for viewing and editing properties of selected Tekla model or drawing objects. The documented workflow is selection followed by property changes in the dialog; the two versioned directories provide parallel implementations. The excerpts show model property access and drawing-dimension updates, but not the dialog’s dispatch to individual property adapters, so those links are dashed and unverified.

Main entry points: [`16.1/Form1.cs`](https://github.com/teklanology/tekla-properties/blob/master/16.1/Form1.cs) (16.1 dialog), [`17.0/Form1.cs`](https://github.com/teklanology/tekla-properties/blob/master/17.0/Form1.cs) (17.0 dialog), [`16.1/ModelPart.cs`](https://github.com/teklanology/tekla-properties/blob/master/16.1/ModelPart.cs) (Model parts), [`16.1/ModelWeld.cs`](https://github.com/teklanology/tekla-properties/blob/master/16.1/ModelWeld.cs) (Model welds)
