2016-17 Door Library - Head Height

A comment was submitted to an earlier post about the new library of door families that came with the 2016 release. The question had to do with changing the head height of these doors. There are two folders (see the images in the other post): Residential and Commercial as well as a smaller collection of doors that are more similar to the past door library we had, but using a new naming convention.

The doors in the Commercial folder have an Instance parameter called Masonry Frame which toggles on/off a solid form that adjusts how thick or high the head of the door is. This image is the same door side by side but with the parameter off on the left and on for the door on the right.


The doors in the Residential folder don't share this family strategy. Neither do the individual door families that are found in the root Doors folder. What is visible on the residential doors is trim, not a frame. The trim is designed to turn off if the Door Offset parameter is not set to zero. The frame form they do have are based on a sweep that doesn't allow for varying its dimensions.

Like all families, how they were conceived of and then created greatly affects their usefulness. In the case of the comment posted, the commercial collection of doors may work for them where the residential ones probably won't; not without some fundamental changes to the families themselves first.

Trim Multiple and Multi-Select

I find that I consistently forget this is possible, to use a crossing window to select more than one element to trim or extend multiple elements at once. Don't forget Steve! Maybe now that I've written that I'll start remembering more often, hopefully. The following video is just the tooltip video that runs if you hover over Trim Multiple long enough.

Fill Pattern Alignment

I responded to a thread at Linked In this morning, something I almost never do. I find LI too frustrating to spend much time there. Regardless, the sought after result was to get horizontal and diagonal patterns (part of a material assignment) to line up, to appear to connect to each other. This is an image of what was shared in the thread.


The Fill Patterns (Model) need to use spacing settings that will allow their endpoints to meet. For example, if the parallel horizontal lines are 300 mm apart then we can use trigonometry to determine the parallel spacing of the diagonal pattern.

The formula b = c * sin(B) where c = 300mm and angle B is 45 degrees returns a length of 212.1 mm for the length of b. The diagonal pattern will need to use 212.1 mm for its spacing so it will align with the endpoints of the horizontal pattern at 300 mm.


Once the patterns work, it will still probably be necessary to fine tune each pattern's position on the surface of each wall so they each start at the correct location. That's because each wall will place/start the pattern you assign according to its own extents.

I like the the Align tool, I pick a segment of the horizontal pattern first then the diagonal pattern and the diagonal pattern will shift to line up as desired. That's how I aligned the patterns in the second image.

Alternatively we can use the TAB key to select one line within a Model Pattern and then use Move to adjust the pattern's location. If the walls are not parallel to each other it may be necessary to create a section view that allows us to see both patterns and use the Move tool. It may also be necessary or helpful to sketch a Detail Line from one endpoint of one of the patterns so we can snap easily while moving the other pattern's position.

Also, the taller the walls (the bigger the overall pattern) are the more important your choice of rounding (decimal places) for your calculated pattern spacing will be. You may find that the pattern begins to slip past or fall short of the adjacent horizontal pattern the bigger the pattern gets.

Selection Box and Linked Models

I was just thinking that it seems unfair that the Selection Box (reasonably new feature) goes to sleep when you select just a linked file. Maybe I want to crop the 3D view down to just that link? That's when I realized that I happen to have a scope box around the link already. Select the Scope Box and then use Selection Box - et voila!

Yeah, I'm writing as if I didn't just go two months without so much as a by your leave...things have been...hectic, yeah. That's my story...

Revit Safe Mode - Wish Fulfilled

The other day I wrote about David's idea for a Revit Safe mode and Robert Manna responded in a serious way. He and the gang at Stantec created and have just shared an application to do just what we were suggesting. This is a screen shot of it running (from Robert's post).


It runs outside of Revit, prepares for opening Revit without the add-ins you choose to disable. It allows us to be fairly surgical in our troubleshooting even if it's akin to exploratory surgery ... "Hmmm, maybe we need to remove the appendix? No, that wasn't it...maybe the spleen?"

If you're curious head over to Robert's post on their blog for more information and to download the application.
