01 – Introduction and transparency
One of our philosophies at Calcs.com is to be transparent. We don’t want to be a black box. You’ll see every step of the calculation, and you can go deeper: click on any label or result (for example, shear design or shear reduction factor) to see a description, the reference we use, and the equation we’re applying. This is available across almost every step of our calculations.02 – Traffic lights and Member Selector
Traffic lights are visual indicators that show whether a structural check passed, is near the limit, or failed, based on utilization. When you change inputs (for example, increase loads in the Loads section), the traffic lights update so you can see how the design is performing at a glance. The Member Selector helps you choose the right member quickly. When you select a member (e.g. in Size and grade), open the Member Selector to see your Preference Sections first, with an overview of traffic lights for each section. You can see which sections would fail with your current configuration and which would work, then try a larger designation and pick an efficient member that passes.03 – Link loads and units
You can link loads between calculators. For example, create a wood column and link it to the reactions from a wood beam: in the column’s load section, under Lateral movement loads, click Link, select the beam (and the support location), and the column will use those reactions. Clicking the linked label takes you back to the source calculator. If you change the beam (e.g. increase loads), the column updates automatically—no refresh needed. Calcs.com is unit-aware. In inputs like Beam span length you can type expressions such as20 feet + 10 inches or 10 inches × 5, and the conversion is done automatically. You can mix units (e.g. 8 meters) as well. You can also reference variables in other inputs (e.g. use the total length L or L/2 for end locations), and the calculator will resolve them correctly.
04 – Views and export
We offer two in-app views: Standard and Detail. Use the view toggle to show more or fewer calculation steps depending on how much detail you want. When exporting, use the print icon at the top and choose among:- One page summary – essentials only, inputs and results on a single page
- Standard view – balanced detail for most use cases
- Detail view – full calculation steps for review or submittal
05 – Send questions, support and knowledge base
Use the airplane icon to send a message to support. You can grant access to your project so we can see what’s going on. Helpful when you have questions about how we calculate something, unexpected results, or differences from other software. Our support team includes civil engineers. We also have a knowledge base: click through to find articles and design examples (e.g. for Wood Beam). An AI assistant can search the knowledge base—try asking something like “How can I design a steel beam?” to get relevant examples and links.06 – Change material
If you’ve finished a calculation (e.g. a wood beam) and want to see the same setup with a different material, use Change material in the top sidebar. Select another calculator (e.g. Steel beam). Loads and configuration are preserved; only the material and designation change. Load links (e.g. to a column) continue to work—you don’t need to redo the link.Check out the next videos in our onboarding series
