Dimensioning

Recommended Posts

A question for the pro's...

Do you dimension in the design layer or the annotation viewport / sheet layer?

I prefer to dimension in the design layer because when editing the drawing, I have all the dimension info handy.

This is where I usually Dim. However be prepared when you use a VP to show a scale radically different than what you originally designed in as your witness arrow will be either really big or really small. I would Dim on separate layer or class then if necessary you could use annotation viewport to achieve proper sizing of text or whatever the dim or note.

I think it's best to dimension for general purposes in the design layer. Remember, if you accidentally delete a VP (I've done it) there goes all your dimensions if they are annotations.

That said, there may be instances where it does make sense to put some dimensions in the VP annotations. For example, when you are doing a blow up say of a washroom where there will be some special and perhaps not too many special or particular dimensions/notes.

Not coming from an architectural background, I'd be curious to know a little more about your architectural workflow. Are all of you primarily working in 2D or 3D? Are you dimensioning in 3D?

Over the last year I've moved to a full 3D workflow. My dimensioning almost exclusively is done in sheet layer viewports. I think I would find dimensions in the design layers in the way.

Cheers,

Kevin

Prior to VP's a lot of us used a separate design layer for dimensions and other annotations. "Sheets" were accomplished via Saved Views using an interwoven matrix of Layers and Classes. This workflow is still completely viable and is in some respects better than placing all annotations in the VP annotation space. One example: I am dimensioning a Floor Plan and find that a window (or whatever) is not exactly where it should be. In the current (VP) workflow I need to exit the annotations, navigate to the design layer, make the change, then navigate back to the VP and back the annotations... Rather time consuming. In the older workflow all you I need to do is change the active layer make the change and then back to the dimension/notes layer. Much faster. That said, I generally use the newer workflow. But there are many times when I seriously wonder why...

Dimensioning in the design layer seems natural to me.

Sections and details in the VP.

I don't need to unlearn any naughty habits then. :grin:

Interesting topic

I had been annotating and dimensioning in VPs but wondered why also

I generally use the newer workflow. But there are many times when I seriously wonder why...

Therefore best practice it seems it to dimension on Design Layer except perhaps if what is showing on a Sheet Layer VP is at a different scale to the Design Layer it came from

So where are most placing text?

Good point...

Can a VP be locked to prevent this?

Thanks to everyone for the insights into their drawing practices.

Peter, what you describe is how I worked for years. Over the last two years, my process has migrated towards building a 3D model and then detailing it using Sheet Layer Viewports. Almost nothing is drawn in 2D. Other than the odd 3D dimension, I can't really imagine why I would be dimensioning in the model itself. There are one or two exceptions, but putting all of the notes and dimensions into the annotations of a viewport is a really clean, efficient workflow for my type of work.

I'm new to VW and was just confronted with the really large witness arrows when I changed scale on the view port. Why does this happen and is it possible the have the witness arrows stay in scale with the drawing? I can see producing a drawing for sheet size output as well as needing to print an 8.5x11 of the same drawing. I would hate to have the witness arrows continuing to change size on me. Or am I missing something basic here?

(I admit I'm just stating to understand viewports)

Thanks

In scale with the drawing - not excatly but you can work it out

Select the VP - in the OIP down the bottom - Advanced Properties and have a look at Marker Scale

I stumbled upon this thread while seeking an answer to another dimensioning related question. First of all, thanks for the great opionions on this one. I've also had ginormous witness arrows that have caused some frustration.

My separate question is how to override text for one dimension? For example, if I'm showing a series of lines that are all 2' offset from each other, I would prefer to indicate 2'(typ) so I don't have to dim each one and so that I'm obvious in my intention. Editing the properties won't allow normal text, only numerals. Any thoughts? Something obvious I'm missing (probably)?

Thanks in advance. You all are great resources and make my transition from AC much smoother.

Best,

Brian

Wow, yup. Just noticed that solution seconds before returning here to see if any answers arrived. I was about to edit my post to apologize for wasting everyone's time and saw the speedy reply.

Thanks, Pat. Needless to say, I'm a newbie and am learning lots each time I open the program.

A few more dimensioning questions for everyone:

1) How do you override the text of the dimension? Meaning, even though it says 418', I want it to read 453' without moving the witness lines from the endpoints of the object.

2) How can the units for only the dimensions be changed to decimal? I normally work in feet/fractional on my projects, but sometimes for permitting purposes, the municipalities like to see feet/decimal dimensions.

Thanks in advance.

***EDIT***

Found the answer to #2, but wish it could be done on a per-item basis in the Object Properties box..

If you ungroup the dimension the text part can be changed without moving the witness lines, only trouble is it will no longer as a dimension but just become lines and text.

Similar to Pat's answer above - enter the 453' in either the Leader or Trailer fields. Then deselect the "Show Dim Value", so it's the only thing that displays.

Thanks for the solutions, they are both creative work-arounds for a function that seems overlooked.

GWS, I must've missed that possibility. When I right-clicked on the dim, I only saw the option to 'unlock'. I thought by selecting this I would be accomplishing the 'ungroup' you mentioned. Thanks, though, I'll look harder next time.

Monadnoc, thanks for this also. One of my biggest problems w/ VW is that I've had some very simple problems that I've had to 'trick' the program to get right.

I'm really holding my patience with this program, but it seems there's a lot to be desired, and a lot of the issues are ones that ACAD has addressed for years.

This program could be WAY better than ACAD with a little more intuitiveness. And maybe it is past the '08 version I'm using now, but from what I've seen so far, I can't justify spending money to take that chance. I'll just have to keep clunking through and resist going back to the dark side with all my might.
