Auto Boundary & Dimension is a productivity plug-in forAutodesk® AutoCAD® that automates several common drafting tasks through a single, easy-to-use interface.

Getting Started

Once installed, you can launch the plug-in directly from the AutoCAD ribbon by navigating to the Add-ins (or Plug-ins) tab and clicking the Auto Boundary & Dimension button. Alternatively, type TT or AUTOBOUNDARY in the command line.

Key Features

• Auto Boundary:Select any combination of lines, arcs, polylines, and blocks. The tool calculates enclosed regions and automatically draws closed polylines around them. You can filter by layer, set a minimum area to skip small regions, apply an inward or outward offset to the result, include objects inside blocks, and optionally delete the original objects after the boundaries are created. Press Esc at any time to cancel the operation.
• Auto Dimension:Select objects, and the tool automatically places linear dimensions along them. You can specify which layers to target and set the offset distance between the object and the dimension line. Blocks can also be included in the selection.
• XRef Reload:Quickly reload a selected external reference (XRef) without opening the XRef Manager.
• Advanced Flatten (Z-Axis Tools):Check your drawing for objects with non-zero Z values. The tool reports how many objects have Z-related issues, broken down by entity type and layer. You can then flatten all of them to Z = 0 with one click. This can be applied to the entire drawing or to a manual selection.
• Fix Islands (Hatch Tools):Sets the island detection style to "Normal" for all hatches in the drawing. This can be applied to model space only or to all hatches, including those inside nested blocks.
