Gonna finish up the week with a very easy tip, yet very powerful for those complicated designs that use all those mathematical formulas and what not…
Hopefully, by this point, you know that you can simply enter a length to determine a wall or line length, or really anywhere you can input a dimension. Simply type 100′ and hit enter et voila! 100′ of whatever you were placing. Did you know, however, that you can do the same thing but with formulas!?
It’s very simple. Instead of typing the normal dimension in like this:
You instead begin it with an ‘=’ like this:
You can use any formula context that revit allows. I would suggest searching in help for “formula” to find out the terms and syntax that you can use.
Like I said, simple and quick, just like we like it here at Revittotd.com! Hope you learned something, and thanks for stopping by. Hope to see you again soon!
What’s this? I’m keeping my word? Two tips in one week?! Well, don’t let it fool you. I cheated. I wrote these 2 days ago 🙂 So let us continue on and wrap up this little lesson on linked model visibility.
First I want to thank my Buddy Gerry Hogsed for letting me use his house design. It is a project that he copmleted in school studio, and received VERY marks with!
So last time we talked about the easy ones, By Host and Custom. If you need a recap, click the Previous post link. So lets say you have a project where you have two sections of a building in one view. The second floor level in your main model is at 10′ AFF and the second floor in your linked model is at 15’AFF. How do you get them to look right in a single view? This is where By Linked View comes in. Essentially we set the view up IN THE LINKED MODEL before loading it in. Let’s take a look at how this is done.
So obviously, the first step is to set up your views in the linked model. This includes VG, View Range, Plan regions, etc, etc. Whatever you do in the view you are linking, is what is going to show up in the main model once you link it in.
Be sure you name your view accordingly, IE: Linked View – Second Floor. You’ll see why in a minute. Don’t rename the current views you are using. Instead duplicate them (with detail if needed) and name them accordingly.
Once the link is loaded into your model, summon the View Graphics dialogue (‘VG’), and head to the Revit Links tab.
Change the Display Settings to By Linked View.
We now have an option to select from a drop down box. If you drop that down, you’ll see that there are some views here to choose from that are in the Linked model. See now why we named our view accordingly? Can you imagine trying to guess which one it was in a large model? Select the correct view, and click OK a couple of times.
We can now see that our linked model now behaves just like the view we set up in the link.
Why do this over Custom? Well, Custom only allows you to set things such as category visibility and overrides. By Linked View, as you can see, allows us to control View Ranges, Plan Regions, etc. Everything that we can control in the view of the linked model, can be transferred to this view using By Linked View.
Yes, I can hear the gears turning now. You see why I saved this gem for last? I hope you have taken something from today’s Revit TotD, and hope that it brings you back for yet another. Have a great day!
I’m slowly but surely trying to recover from moving and settling into a new job. I’m having to force myself to sit down and make time for RevitTotD, but I’m glad I do it every time that I do! This week, I’m going to have 3 tips… that’s all there is to it! Baby steps, baby steps!
Linking models is fairly straightforward. It’s when you need to start customizing how the model needs to look in different views for consistency with the main model that you start to get deep in to those infamous nested Autodesk dialogues! So how do we start customizing? Like so…
There are three types of visibility graphics control for linked models: By Host, By Linked View and Custom.
You access these settings through the Visibility Graphics (‘VG’) dialogue > Revit Links tab
In this tip, I’m going to cover By Host View and Custom. Part 2 of this tip will cover the By Linked View option.
By host view is by far the easiest way to control your graphics. It’s as simple as turning categories in your main model on and off as you normally would in the VG dialogue. If you want the walls in your model AND linked view to be hidden, simply turn them off the in VG dialogue.
What if you need the walls and floors in your link to be off, but you want to leave them on in your main model? Ah, this starts to get slightly trickier, but is still accomplished with only a few clicks. First, you need to set your link to Custom mode in the VG dialogue. NOTE: These settings are BY VIEW! Setting this up in one WILL NOT affect other views, this is where view templates come in to play 🙂
Depending on the category you want to control, go to that respective tab (walls and floor = model categories, levels = annotation categories) and set those categories to Custom as well.
Click OK a couple of times and see the results. Notice our main model walls are visible while our linked model walls are not.
Same concept applies to the Annotation Categories. Let’s say you have redundant levels in your linked model and don’t want them showing up in your main model. Same as above, but simply go to annotation categories and turn off levels.
Well, that was quite a mouthful for one tip! So, mull around on that for a day or two, and then come back for part2 of this tip when we talk about the By Linked View options which REALLY let’s us customize every bit of the linked model. Thanks for stopping by, and I hope to see you again for yet another Revit TotD!
Ever found yourself working on a model with models linked in and you need to make some modifications to the linked model? You go to open the linked model and you get that annoying message that tells you the model is open already and will be unloaded from the other model if you continue. This is the point at which new revit users mumble under their breath “This wouldn’t be a problem if we were using AutoCAD.”
Fear not, here’s a simple little tip that should ease the burden of making quick changes to linked models.
You sure you won’t be mad when you see the simplicity of this little tip?
OK, here goes: Open another instance of revit, load the revit model that you want to make the change to… wait… waaait… and there you go! You now have both models open at the same time without unloading one model from the other in order to work on it. Now to update changes, you simply need to save the model, then reload it in the other model through the Manage Links tool.
