Settings
On the Primary panel click Settings 
to open the settings control panel.
There is also the Settings 
button on the Start page.
General
On the General tab, you may set the Renga interface language. Restart application after language changing.
Graphics Mode
There are following graphics modes available in Renga:
- Use hardware graphics acceleration.
- Enable lighting.
- Show shadows.
- Smooth edges of lines.
- Display true line thickness.
- Display views as raster.
Disable Use hardware graphics acceleration and Smooth edges of lines options if the Renga works slowly or you are experiencing some trouble creating a project.
Disable the Display true line thickness option to increase the accuracy of specifying object snaps in level tabs.
Enable the Display views in raster option to speed up working with views in Drawings.
Graphics modes affect on-screen display only and do not affect printing or export to PDF, DWG/DXF formats.
Size of Text and Other Items
The following User Interface options are available:
- Display the Virtual Reality command. Displays Virtual reality
button at the bottom left corner of the application.
The button initiates connection to Oculus Rift headset for viewing the model in the virtual reality mode. - Show thumbnails instead of icons. Allows to enable thumbnails with the current state of drawings, levels, assembly styles, sections and elevations on the Project Explorer tab.
User Interface Options
View scale. Scale settings allows you to change the size of text and other elements of the Renga interface. We recommend that you use Auto(100%) scale in Renga.
Default font
In Renga you can use any fonts in TTF and OTF formats when creating project documentation. When collaborating and sharing a project with other users, share non-standard fonts with the project. If the specified font is not found on the user's computer, the default font will be used when opening the project
Parameters of the font that will be applied by default:
- Font family. Defines a typeface of the font.
- Font style.
- Font size.
Collaboration
In the Collaboration tab, you can set the server settings for synchronization and enable automatic synchronization of changes.
- User name.
- Server name or IP-address – the name or IP address of the server the project is published on.
- Port.
- Server access key.
By default, synchronization starts using Sync 
command (F5). To automatically receive and send changes, enable the Automatically sync changes option. For details, see Collaboration.
Navigation
On the Navigation tab, you may set one of the navigation modes and specify visibility of a model rotation center.
Navigation Mode
Object Mode. Default mode. This mode allows you to control the object with a keyboard and a mouse.
Camera mode. This mode allows you to control the object with a keyboard and a mouse.
You may also use a 3D mouse in any navigation mode in Renga.
Rotation Center
Display settings of the rotation center:
- Hide
- Show on motion.
- Always show.
License Server
On the License Server tab, you can specify the names or IP addresses of the primary and alternate License Servers if your organization has purchased network licenses. You can also use Automatically detect License Server check if it is located on your local network.
Extensions
In the Extensions tab you can see all installed Renga extensions developed using the Renga API.
To add in an extension:
- Open Renga installation folder.
- Create and open Plugins folder.
- Insert the folder with the extension files. The extension folder name must match to the file name with the *.rne extension.
- Run Renga. On the Primary panel, click Settings , go to the Extensions tab.
- Make sure that the extension is on the list and it is selected.
To temporarily disable an extension, clear the required extension check box.
Renga must be restarted after activation/deactivation an extension.
Export
On the Export tab, you can select the parameters to export the model to IFC4 format.
To determine the model representation, specify:
- Type mapping file.
- Parameter mapping file.
- Objects to layer mapping file.
Mapping files are JSON files that can be opened in any text editor.
You can edit existing files or select other ones, but the document structure has to remain unchanged. We recommend to create copies of the source file for different export purposes. When creating a copy, set the value of the first entry in the parameter mapping file to export the model from Renga to IFC.
To match the Reference View the following settings are set by default in Renga:
- Approximate curves with lines and arcs.
- Export "Body" openings as "Reference".
- Split objects with layered materials into parts.
To export the exact geometry to IFC, uncheck Approximate curves with lines and arcs.
To export objects that may contain openings as SweptSolid, uncheck the Export "Body" openings and holes as "Reference" option. If this option is checked the geometric representation of objects with openings includes a openings and holes geometry description when exporting to IFC.
Uncheck the Split objects with layered materials into parts option to not splitting objects.
To export objects without taking into account cutting and the shapes of beam end faces, enable the Export geometric representation without cutting option and disable Approximate curves with lines and arcs, Export "Body" openings and holes as "Reference", and Split objects with layered materials.
Check the valid geometric representations of objects.
For more information about exporting to IFC format, see IFC Export.
