ST500 Step, Step Ladder & Step Bridge Revit Instruction Video
This video will serve as an overview of the range of ALTO Step Ladders and Bridges by SAYFA that we at IGS BIM Solutions have created as native Revit families. So the products in question here can be found on the SAYFA website by navigating to the ST500 Step Ladders and Bridges product page where you’ll see we have a range of steps, step ladders and the step bridge.
Jumping into Revit, we have a section of the virtual showroom file here with all of the families and their types laid out, ready for easily copying and pasting into your project. I’ll just work from the front to the back here because we are sort of getting from more basic to more complex as we go further back. So just firstly, we have the steps.
So these are two families that we’re seeing on screen here with two types each. So that one, there is our single step and then we have the double step. And then within those families we have the option to select from either a step over or a step up. So these are non hosted families, which means that we would simply just click where we want it using the spacebar or the rotate tool after placement, we’re able to position that how we want it.
But yeah, that will just go to a level in our project and always be vertical. When we’re talking about the ladders, so we’ve got these broken up into either the standalone step ladder which is your ST570M and within that 570M family, we have six available heights which reflect the one through to six metre increments. For the platform ladders, which are these back here, so we have all of the ST575Ms, 580Ms and 582Ms. So those 18 types in total are all built into a single family with an accompanying type catalogue that can be accessed when inserting these files into your project. If I just jump back to the standalone step ladder and we’ll go through some of the common parameters that apply both to the standalone and the platform step ladder.
So firstly, in our instance properties here, we again obviously have the ability to set a height from FFL, which will give us a vertical offset from the hosting level. We then have this desired step height. So this desired step height is specifying the spacings that we would ideally want between the treads. So if I put in a value here of say 280 you’ll notice that this greyed out actual step height parameter will automatically validate my input to the desired step height to give me the closest available equal spacings of treads.
So if we were to put in something outside of the range of the accepted values, so 500, there are some smarts working in the background here to validate the tread spacing. So we’re never going outside of the minimum or maximum spacing. So here I’ve put in 100 and you can see that it just defaults to the minimum spacing of 200 in that case. Coming into the edit type properties here, so my desired ladder height is again driven by the type. So we’ve got these standardised one metre increments. If you were wanting, say, a 1.5 metre overall ladder height, it would be recommended that you don’t just adjust this value here because what we’re actually doing is changing the height of all two metre high ladders in our project.
So you would duplicate the type, give this a unique name and change the desired ladder height to 1.5 metres. Now the code itself, so the model number will not change because essentially this 1.5 metre height is a cut down 2 metre. So that’s fine. That will automatically calculate what code that needs to be based on my input to this parameter here. And if I hit okay, the geometry will update and will not affect any other instances of the two metre height that I might have placed previously in my project. So I’ll just undo that and we’ll look at some of the visibility parameters. So where there is a requirement for a lockable door or a cage, we have these visibility tick box parameters which can be toggled on or off.
So they are on by default and they’re on for all types. You’ll notice, though, on these smaller ladders where the lockable door or the cage are not applicable, turning these parameters on or off actually has no impact on what we’re seeing in our 3D view. However, when we do get the lockable door or the cage coming in by default on these larger ladders that do require them, you have the option to turn these off using the appropriate tick box parameter. For the platform versions of the step ladders, those same parameters apply. So the desired step height and the show cage and lockable door options all exist in here. With the breakdown of the 575, the 580 and the 582Ms the difference between these is the length of our platform. So this one here we have a 300mm platform that comes off the back of the ladder this one is a .9 metre, so 900mm and then a 2 metre platform coming off the 582M. So same principles apply in terms of hiding the cage or lockable doors if we wanted to. An additional parameter that’s been built into these platform ladders is we have the desired platform roof offset, which you’ll notice is zeroed out by default.
But if I just zoom in on this one here, what we can actually do is specify a value in here of, say, 150, at which point we will see the leveling kit come into play and that will go onto the bottom of our platform posts. And the dimension of that can be driven by this parameter to have this leveling kit come down to the surface of our roof or slab or whatever we’re going to.
There are some rules built into here. So again, if we were to put, say, 500, 800, these are just defaulting to the maximum possible offset here that this leveling kit can achieve. But yeah, otherwise, if that’s not required, if you zero that out, we’re no longer going to see that additional geometry. In terms of the required space clearances that we’re seeing on all of these components these can be toggled on or off on an instance basis using the required space tick box. So that will turn it off on that specific instance of ladder. Alternatively, as with all of the other SAYFA content that has a required space subcategory, we can access the visibility overrides for a particular view and navigating to the specialty equipment I can turn that required space subcategory off, which will ensure that in this view we’re no longer seeing any of those 3D clearance zones.
Taking a look now at the bridge. So we have some familiar parameters in here around our tread spacings, but also our ladder heights on either side. So these are instance based and we have different types, so four types in total to reflect the four available platform lengths. So a 900, a 1.2, a 1.5 and a 1.8 metre. So in these bridge components, we have independent control over the side one height and tread spacings, and I’ll just show that quickly.
So if I put 150 here again, we’re getting validation happening in the background to ensure we’re not going beyond that minimum 200. And if I change this to 300, we might sort of see more easily that we have different tread spacings on either side in that particular scenario. Otherwise these could just easily be equaled out. We do have instance based control over the ladder height on either or both sides.
So in here I might have a six metre on one side and because we’ve now got a ladder that requires the lockable door and cage element, you’ll notice that that does automatically generate the geometry of those components. And again, I can use these instance based tick boxes to turn those off if and when I require. So the higher of the two ladders, if they’re actually not equal in value, will be the one that goes down to the hosting level.
So essentially when I’m driving the manufacturer height from FFL in this scenario and we specify a 500, we’re going up 500 from the hosting level to the underside of that longer ladder. I were to change these dimensions around so this becomes two metres and this becomes six metres, you’ll see that now, because that’s the longer ladder that one there is extending down to the hosting level and the spacing between the bottom of that ladder and the hosting level will essentially be this manufacturer height from FFL in that scenario. So similar to the platform step ladders, we do have the ability through the desired platform roof offset parameter here to apply a value and have that leveling kit come in on any of the platform posts to automatically get this additional geometry that extends down to the level that we’re trying to host this platform to.
As with the Walkway and the PROTEX content, you’ll notice that the platform and the surface of the steps are using a custom material. So these do require a custom image to be mapped to your Revit rendering settings. And the details of that are outlined in the user guide document. But yeah, that essentially ensures that we get realistic rendering of these products without compromising the performance of the project by physically modeling any 3D voids in the platform itself.
So hopefully that’s been of use. And as always, if you have any questions, please reach out. Otherwise we do have the accompanying Revit User Guide that goes along with all of the content in the SAYFA library. So feel free to have a look at that and see if there’s anything else covered in there with this particular product range or any other ranges that you might be interested in.
