Modelling Existing Steel In Advance Steel

Not all jobs are brand-new portal frames sitting on a slab, sometimes we need to detail steelwork that connects into existing steelwork. We still want to take advantage of the checking tools inside of Advance Steel and we also need to ensure that the bolts we are modelling are long enough to bolt through the existing steel. Therefore, this existing steel needs to be modelled but we don’t want to accidentally end up ordering these items.

This blog will run through the steps for modelling existing steel and ensuring it doesn’t show on any of our fabrication output.

       1. Model the existing steel as you would any other item

       2. In the naming tab set the model role to “Existing”

       3. While in the naming tab click the “Define as main part” button, this will allow us to turn off the numbering and bill of material option for the assembly number and prefix

       4. In the Behaviour tab make sure you untick “Used for numbering” and “used for Bill-of-Material” for both the Single part and the Assembly then close the dialogue box

       5. Select all of your existing steel items then through the layer properties you can change the layer type from “Beam” to “Existing” so they are easier to see

       6. These steps will give you an Advance Steel element that you can connect into but it wont show on any of your fabrication output.

It is also useful to help the erection team to differentiate between steel to be installed and existing steel. The simplest way to achieve this is to open the GA drawing, select one of the existing steels, then right click and choose “Select similar”. This will select all existing steelwork in the GA, then right click again and choose “Advance properties”. Once in Advance properties you can change the visible linetype to a dashed line or whichever linetype you require.

This process, with some Management tool changes and CTB file configurations, could be automated along with some drawing customisation to achieve the output below, which is an extract of the plotted PDF file. The actual DWG file will show the existing steel as solid lines but when printed to PDF or hard copy the lines will be dashed as shown below.
