Select 'Standard Truss Design' or 'Custom Truss Design' from the 'Design Requests' section of the left-side menu.

• Choose Standard Exposed Trusses when:
  • Roof Pitch is 20, 25, 30 or 35 degrees.
  • Span is 1.8m to 7m.
  • Truss member sizes can be fixed.
• Choose the Custom Exposed Truss option if you want to customise the design aspects like pitch, long span or member sizes.

You can also find more information about the different types of design requests by using the 'Design Requests' link.

An exposed truss form has four sections, while there is also some extra help on the right-hand side.

• Diagram
• Site Parameters
• Member Selection
• Design Parameters

Note that any values already set in the project settings are pre-filled. This applies primarily to the Site Parameters section but also to some parameters from the Design Parameters section.

Also, on standard trusses, the questions are fewer. The images of specific sections below are from custom trusses.

If a question has extra help, you can view that help by clicking on the question mark symbol next to the question.

Clicking anywhere on the page will discard the box with the help text.

Enter or edit the site parameters, such as wind zone, snow zone, etc., in the respective section.

Edit the member selection details, such as the desired surface finish or width and depth of various parts of the truss (custom truss only).

Enter or edit the design parameters, such as roof pitch, roof type, etc. (top part of the section).

Refer to the truss diagram for dimensions to ensure these are correct.

Enter a detailed description of your desired solution.

Please note any specific requests or unusual details that the design engineer should be aware of when checking the truss design.

Click 'Add attachment' to attach a complete set of drawings, including floor plan, relevant elevations, roof framing plan and a section through the proposed truss location.

If helpful, you can select to attach multiple files simultaneously.

The added attachments are listed below. You can check the files by clicking on their name. In case of a mistake, you can remove an attachment by clicking 'Remove'.

Click 'Continue' at the bottom of the form.

Enter or update the project details and click 'Continue'.

Note that the details are pre-filled if they have been set on the active project.

If you need to change anything on the request, you can click 'Back'.

Review the cost estimate.

Below, select a billing method, invoice or account, and enter the relevant details.

The invoice option is pre-selected. The account option asks for a branch and a purchase order number instead of a billing address and email.

Read the terms of agreement below the form and check the 'I agree to these terms' box.

Note that the terms are slightly different for different billing methods.
