  • JTB TimberTool is an add-on to AutoCAD Architecture (ACA) or ADT based products including MEP and Civil 3D.
  • JTB TimberTool makes it easy to convert closed polylines into mass elements and makes the bounding box width and depth correct for scheduling purposes.
  • The product was initially created for usage with timber but works with lumber, structural steel or concrete shapes.
  • Style, layer, extrusion depth (or thickness) can be specified.
  • Property sets can be attached automatically if they apply to mass elements.
  • You can manually specify the alignment axis so that rotated polylines are converted correctly.
  • You can specify if you want to retain the polylines or not after conversion.
  • See this short video on how it can be used.


When not registered JTB TimberTool works as a free trial that is fully functional except that you can only convert three polylines per AutoCAD session. When purchased it can be used without restrictions.

If purchase has been done via Autodesk App Store the download is available on the Autodesk App Store My Downloads page. Sign in with the same account used when purchasing.

Timber Creation Tool Dialog Box

Make selection of the settings as needed.

Select the style for the mass element.

Select layer or inherit the layer of the polyline.

Specify the extrusion depth.

Add property set automatically will add any property set that applies to mass element objects.

For angled timber it can be useful to select prompt for alignment axis 2 points.

If the polyline should be deleted select erase 2D geometry.

Click on Select Polylines and select one or multiple polylines.

Press OK.

Before conversion to mass elements

Conversion using ExtrudeLinework (notice that the bounding box is not correct.

Result after using TimberTool

Using ExtrudeLinework notice that the Width and Depth is based on the bounding box not the actual mass element.

Notice that after using TimberTool the Width and Depth is correct as expected to be.
