Welcome to the documentation for the Medeek Truss extension. Medeek Truss is a SketchUp Extension that provides a simple interface for creating accurate 3D truss and roof geometry within SketchUp. This extension utilizes the SketchUp Ruby API programming interface and is compatible with the latest SketchUp releases (SketchUp Make 2017 64-bit and SketchUp Pro 2023 64-bit) as well as previous versions (2017, 2018, 2019, 2020, 2021, 2022).

What Can You Do with Medeek Truss

Currently, the plugin allows the creation of the following common truss types (Metric and US/Imperial):

Specialty Truss Types: Timber Trusses (metal plates with bolts): Floor Joists/Trusses: Truss Sets: Rafter Roofs (Metric and US/Imperial): Minor Roofs (Metric and US/Imperial): Complex Roofs (Metric and US/Imperial): Skylights (Metric and US/Imperial): Electrical, Custom and Subtractive Geometry: Engineering (US/Imperial): Trim and Extend Members: (MOVED TO THE MEDEEK PROJECT EXTENSION - JAN. 11, 2023) All truss types are drawn/designed utilizing industry standard practices for web location (panel lengths), web scarfs at joints and a 1/4" typical butt cut. Floor trusses are drawn using the Modified Warren configuration with one central chase, options for ribbon cuts and top or bottom bearing are also provided. Additional truss types are in the process of being added, as well additional customization and features such as raised energy heels for all truss types.

Custom layers can be enabled in the global settings which allow roof, wall and floor components to be placed on specific layers. Truss connector plates are available for select truss types and can also be enabled within the global settings.

Auto assignment of materials (colors and textures) are available as an option within the "Materials" tab of the global settings. Currently available materials are: Lumber, Pressure Treated Lumber, OSB, Plywood, LSL/PSL, and Metal Plate Connectors. Roof cladding can be specified within the global settings ("Sheathing" tab) and cladding thickness and roof material/texture can be set by the user.

The plugin allows the user to create an array of trusses by simply selecting three points which form the bounding rectangle (bldg. width x bldg. length) of the truss array. The number of trusses is automatically calculated based on the on center spacing and the building length.

Each individual member (chords, webs, sliders, wedges etc...) of the truss is modeled as a group with the entire truss forming a component having a unique name (ie. FINK_TRUSS_24_20171019123215). Arrays of trusses are created by invoking multiple instances of this truss component. This allows for modifications to all the trusses in an array by simply modifying one truss. Creating each member of the truss as a group allows modificatons or deletions to each member without affecting the rest of the truss geometry. Additionally each truss assembly (Array of Trusses) is grouped in order to facilitate future adjustments to the truss assembly as a whole.

Automatic gable end truss insertion is now available for all truss types except attic trusses. The gable end truss option is currently being added to the attic truss type and will be available in future releases. Other advanced features currently being considered for future releases are: Transistion Trusses, Hip Sets, Hip Rafters, Dormers, and Dynamic editing of Truss Components.

Advanced options allows for the creation of sheathing, rake boards, fascia, heel blocking, roof returns (hip, full), battens, counter-battens and outlookers. These options are currently available for the following truss types: Common, Attic, Monopitch, Scissor, Dualpitch, Tail Bearing, Mono Scissor, Tray, Coffer, Gambrel Attic, Symmetric Cathedral and Floor; and for the following rafter roofs: Gable, Gable with GLB, TJI with GLB, Hip, Shed and Shed with Ledger.

Advanced options also allows for the creation of gutters and downspouts for truss and rafter roofs. Specific gutter configurations can be customized within the gutter tab in the global settings. Currently four different gutters styles and two different downspout types are available in the global settings.

I-joist and solid sawn joists can be inset into the foundation with or without a ledger board and the appropriate hanger can be modeled as part of the joist component. Within the global settings I-joist manufacturer's logos can be enabled or disabled for ease of identification.

With the Medeek Truss Plugin, you can accurately depict typical roof trusses, floor trusses, rafters, and floor joists within SketchUp and better validate your architectural models.


The Truss Plugin is integrated with the Medeek Truss Designer and can provide engineering data (loads, internal forces, reactions and deflections) for specific common truss types (ie. King Post, Queen Post, Fink, Howe and Double Fink). The plugin is also recently integrated with the Medeek Beam Calculator and can automatically load the design parameters from SketchUp in order to check bending, shear, bearing and deflection for typical North American glulam beam sizes. Engineering for other truss types as well as rafters, joists and sheathing is in the process of being added and will become available in future releases. For additional engineering tools and site criteria maps please visit our Resources page.


This document is intended for architects, engineers, designers and homeowners who are using SketchUp as their primary 3D design tool. It provides an introduction to using the plugin and reference material on the available parameters/options for its use.

License and Limits of Use

The Medeek Truss Plugin is a proprietary softare developed for use with the SketchUp 3D modeling program. There are currently no limits to its use for both personal and commercial applications.

Design Parameters - Truss Geometry

The following items are typical design parameters than can be modified by the user to define the truss geometry during the truss creation process:

Additional parameters and options are available for specific truss types (ie. attic, scissor, floor), rafters and floor joist products.

The recent versions of SketchUp allow you to install zipped Ruby files or extensions (.rbz) directly within SketchUp.

To install the Medeek Truss extension (.rbz file format) within SketchUp 2017, 2018, 2019, 2020, 2021, 2022 and 2023:

  1. Login into your computer as an admin before installing any Ruby scripts. This will make the installation go more smoothly and ensure that files get installed in the proper places.
  2. Within SketchUp select Window > Extension Manager (Microsoft Windows) or SketchUp > Extension Manager (Mac OS X). The Extension Manager dialog box is displayed.
  3. Click on the Install Extension button. The Open dialog box is displayed.
  4. Locate the Ruby zip file to install (.rbz).
  5. Click on the Open button. SketchUp will install the extension and display a security prompt.
  6. The plugin will display a prompt for your plugin serial number (default value is "TRIAL") if this is a new installation.
  7. The Medeek Truss Plugin will now appear in the list of available extensions.

* Note: If you have previously installed the trial version of the extension and are upgrading to the fully licensed version it is not necessary to re-install the extension. To activate the full version of the extension:

  1. Click on the Global Settings icon (three slider bars). The Global Settings menu is displayed.
  2. Click on the License Tab within the global settings. The License Tab menu is displayed with an input box for your serial number.
  3. Enter your serial number (case sensitive) and then click Save Settings button at the bottom of the menu. A popup message will appear confirming your license registration and the Medeek Seal will be displayed.
  4. Restart SketchUp for the license activation to fully take.


If you are a registered user you can obtain the latest version of the plugin, at no additional charge, by logging in to the Account Manager. Click on the plugin icon and then on your order number, if your order was placed within the last year then you will see a download button which will allow you to obtain the latest version. If a year has expired since you purchased a license then a upgrade button will appear which will allow you to renew your license at a reduced rate for another year.

Once you have downloaded the new release, completely uninstall the existing extension prior to installing the latest release (click the Manage tab within the Extension Manager to uninstall). Failure to completely remove the existing plugin may cause some files to revert to the older version and impair the functionality of the plugin.
