Which design checks does Shapemaker do?

Shapemaker performs a wide variety of design checks, depending on the selected tower type and the design code. In this article, we present a non-exhaustive list of these checks.

Shapemaker is continously being developed, and depending on the industry trends and customer needs, we add new checks and annexes monthly. Therefore, this list is not complete, and we do more checks than what is listed here.

In addition to what's written here, have a look at the full report to see which checks have been performed for your analysis.

If you're curious about a certain check not mentioned here; use the in-app chat to ask our engineers directly, or contact us.
