Written around problems that come up in real work rather than around a feature list. Each one tries to explain where the criteria come from.
How to open an IFC file online, with no software to install
Received an .ifc file you cannot open? What the format is, why a text editor shows nothing useful, and the full steps to view the 3D model in a browser.
Sending a steel model to a client or to the shop
Sending the IFC means they cannot open it; sending screenshots means they cannot see the angle they want. One browser link solves it — and here is how to set passwords, expiry and visibility.
Clash detection on steel IFC models: why you get thousands of results, and how to get down to the ones that matter
The usefulness of clash detection is set by its false positive rate, not its geometric precision. Why bolts through holes must be excluded, why construction gaps are not defects, what clearance threshold to use, and what happens when a model has no assembly structure.
Steel model health checks: finding what cannot be fabricated or erected, before cutting starts
Elements over stock length, single pieces beyond crane capacity, identical marks with different geometry. These are invisible on a drawing and expensive on site. What rule-based checking covers and where the criteria come from.
Quantity take-off from IFC: weights by section, material and mark
The model already holds every element's section, material and length, so take-off should not mean counting drawings by hand. How to define the summaries, and which missing properties throw the numbers off.
