Trey Suppress Spaces

Okay this is a follow up to redux. Erik pointed out that we can still override the dimension style to ignore the project settings and Suppress Spaces. Here's what a string of dimensions look like with no overrides in play.

Here's what the same string looks like with overridden dimension style and Suppress Spaces on. Notice that the dimensions are tighter (good) and the prefix and suffix are closer too (not a better look though).

This means that we can still get what I though we lost. It seems the Suppress Spaces option is limited to altering the prefix/suffix while the dimension style needs to be overridden to get it.

Since I can put a space in between the prefix and dimension value, same for suffix, I'd prefer that the style could use the more obvious Suppress Spaces option and let the dimension stay connected to project units. I'd be far more likely to use it that way than ever use it to mess with prefix and suffix which I seldom use in conjunction with a real dimension value either, definitely the exception rather than the rule.

Suppress Spaces Revisited

In Revit 2012 (wrote about this earlier) we had the ability to shrink imperial dimension values a bit.

The upper dimension shows what 2012 did when Suppress Spaces was checked. The bottom shows unchecked. In 2013 we lose that. In my earlier post I missed/forgot that Ryan responded explaining what changed. Rats, I don't like the change, I want my old suppress spaces back by golly! This is what we get now (using my best Craig Ferguson accent, "It makes littul sense tah meee").

Revit 2013 - Suppress Spaces in Dimensions

Revit 2013 changes the means to reduce the overall size of the text displayed in a dimension string, particularly noticeable to people using imperial units. It was tied to the project units and you had to alter a dimension style to not use the project units settings in order to use it.

This is the new location for the option, found in the Type Properties for a dimension style.

This means your dimension styles can continue to depend on the Project Units as well as suppress the spaces in dimension values. A subtle but more logical approach I think.

However in testing it appears to be broken... The option for Suppress Spaces exists in the the Project Units dialog. If I turn on the feature it affects dimension styles downstream and the option in the dimension style should then work as an option to remove it but it doesn't do anything. Odd...

Revit 2013 - Diameter Dimension

It might seem surprising to someone unfamiliar with Revit but it has not had a diameter dimension option for twelve years, since the beginning, only a radius (radial). That said, it has never prevented me from getting something done, just inconvenient at times.

In my view, any hole you make (or need to describe) with a drill is better dimensioned with a diameter value, you buy drill bits and core drill sizes based on diameter. More often than not I used text and a leader to "point" at a hole and say what diameter it needed to be. I didn't need a dimension for that.

Now for walls that are curving (or soffits or ceilings etc), those are better laid out with the radius. Give a contractor the diameter and they just have to divide by two anyway. In fabrication I used diameter dimensioning all the time. In construction on site, very seldom...unless selecting a drill bit.

So no diameter dimension for many years, but no more...Now it does!

One place I will be very grateful for the diameter dimension is in the family editor. What was dreadful was defining pipe diameters there without it (or round duct fittings for that matter).

Splitting a Dimension String

The media embargo has been lifted. As the noise regarding the next release of Revit grows I thought I share a feature that's in tune with me enjoying the "little things", refinement. They've added the capability of removing a segment of a dimension without using Edit Witness Lines.

It's pretty simple, though maybe not all that intuitive. You use very Reviteristic concept hover > tab > click to select. You place your cursor over the segment you want to remove (hover), press (don't hold, that's disco tab) the tab key until just that segment highlights, next you click to select it and then finally Delete it. You can choose how you want to delete it, Delete Key, Delete button on the ribbon, right-click > Delete...have fun!

Hover > Tab > Select

Press the Delete key

Here's to the little things.

Almost Five Minutes of Dimensioning

I got a question the other day about adding a dimension between a couple corners at a corridor so we could show how much space exists between them. It wasn't really a design factor as much as, "See there is this much!" So while I was talking through that I thought I'd cover a few other dimension features. I ended up recording a video. It's just under five minutes and I've really only scratched the surface of dimension features and settings. You can watch the full size video at OpEd Videos or You Tube.

Show Your Constraints

In Revit we can apply constraints (padlock and EQ) using dimensions. These dimensions can get deleted and if the person doing the deleting doesn't respond to the warning well...the constraint remains intact without any obvious visible evidence.

Choosing Unconstrain will eliminate the constraint when the dimension is deleted. Unfortunately many users just click OK, leaving the constraint to come back and bite someone later, maybe themselves.

For example, years ago, a friend started modeling a tall building. He locked the distance between a few different floors and then later deleted the string. Eventually he needed to change the floor to floor height and Revit crashed. I took a look at the model. When I used Zoom to Fit in an elevation view I noticed that a little padlock appeared when I selected a Level. Revit tends to display the icon for a constraint at the opposite end of what is being examined, usually off screen unfortunately (less clutter with other icons is my theory). Using Zoom to Fit meant I could see the whole level, and the constraint icon, like in this image at the far left.

Software programmers "comment their code" so that it is easier to figure out what a section of code is intended to do later. It's etiquette, good practice, nice... Half the time it's self serving too. I've returned to some code I wrote months or years later pleased to find my own comment helping me remember why I did "that".

To mimic this notion of "commenting our code", I frequently suggest that if this sort of constraint is really important then consider making a duplicate view called Level 1 - Constraints (or somesuch). Lock and constrain it there. With this special view any/everyone can see the constraints anytime they want and see why they are there because you can add a note saying so.

Assigning a Dimension Oddity

Received a question via email asking why Revit seemed unwilling to assign a Shared Parameter that used the Duct Size type to a dimension string. Here's what the SP properties looked like.

The quirky part assumes that you want to select a dimension string and then associate it with the SP. This is what happens when you do that.

I've recorded a brief video to show the result too.
