My woodwork teacher had a saying that has stuck with me since school - “measure twice, cut once”. Whenever I’m attempting a DIY project I always remember this saying, and I have one for Advance Steel detailers “check lots, run your drawings once”, not quite as snappy but equally important.
How many times have you run drawings to find that a plate has not been welded to an assembly, items incorrectly welded together, holes outside the object, or even worse steelwork has gone to site and there is a clash that has not been picked up.
There are lots of checking tools in Advance Steel that can be used to eliminate these errors before you run drawings, or the steelwork gets to site, and I have given a brief overview of each of the tools below, recently I ran a webinar which looked at all the different checking methods, a recording of that webinar can be found here - Checking your Advance Steel Model to Eliminate Drawing Errors.
Clash check – this checks if two items are physically clashing, it also includes tool clearances around bolt heads and nuts and will also check that you have enough space to insert bolts. It is advised to be in 2D wireframe when clash checking as the system will display the clash in red.
Steel construction technical check - this tool is less commonly used but can resolve a lot of errors that would go unnoticed until you were editing drawings. This check highlights design factors such as bolts too close to the edge of the material etc. I used it to highlight any holes that are outside of the object or welds that only connect to one element.
Model Check - This checks items in the model that don't make sense to Advance Steel. A typical example is a beam that has a negative length because an end treatment like a Shorten is longer than the beam itself.
Mark loose parts – this will mark any item that is loose ie any item that isn’t welded or shop bolted to another item.
Clear marking & display objects connected in shop – You might have a scenario where you have a stub section with an end plate welded to a main beam, and if you forget to weld the stub to the main beam the Mark loose parts check wouldn’t highlight the stub as the end plate it welded to the stub making it attached. The clear marking & display objects connected in shop allows the user to select any object in the model and it will mark everything that is attached.
Centre of gravity & total weight information – You may be craning in a welded assembly and need to know the centre of gravity or you might have weight limitations due to manual handling restrictions. The COG will be shown as an AutoCAD point in the model, you should use the “Clear marking & display objects connected in shop” command first, then select the marked objects before clicking the Centre of gravity & total weight information button.
Assembly weight information – This gives just the assembly weight information, you don’t have to have anything selected or mark just click the button and choose any part of your assembly.
Clear marking & display connection means – we have all been in the situation where we open an assembly drawing and it is showing items not supposed to be connected and nowhere near each other in the model. This tool will highlight all the welds or shop bolts connecting the items.
