Fake Revision Clouds in Revit

Well, I said I would post didn't I so here it is:

Ever wanted to add a revision bubble to a drawing in Revit to highlight something on a drawing but not actually add a revision to the sheets? Its one of those things that we used to do in AutoCAD but Revit seems to be almost too smart and doesn't let you do it. A good example of this would be say if you wanted to highlight something on a drawing is in abeyance. Well Revit;s detail line tools don't have a cloud option but there is a nice workaround.


  • Use the standard Revision Cloud command from the Annotate tab to sketch your cloud.

  • Before you finish the command, select all the cloud lines and copy to clipboard using the button highlighted below.

  • Now cancel the command using the red X. You will get the following dialogue box. Hit yes.



  • Now, from the Annotate tab select Detail Line, and rather than try draw the cloud simply select Paste Aligned to Current View from the Paste button drop down which is accessed via the little arrow highlighted below.

  • Hey presto, Detail Cloud lines as requested and no actual revision on the sheets. Nice.


I wish I would take credit for this but in actually fact it was my colleague sat next to me who figured this out today. Nice one Nat. :) 






Back in the Seat...

Well, its been a LONG time.. I hadn't realised just how long its been.. I suppose I have just been super busy on the work front and super lazy on the blog front but this week I was kind of shocked back into the blog world when I met a friendly gent at a BIM meeting in London. He introduced himself to me and said he recognised me from this blog...I was a little shocked but pleasantly surprised to be honest. I was beginning to think that the only person who looked at this was actually me but it would seem that I do have some viewers. So that got me thinking,, I should really make more of an effort to keep posting and building the blog.. So here I am..

So a big thank you to David Wood of Chapman Taylor for giving me the nudge I needed .

Holographic Presentation Material...Yes Please!..

I wouldn't of thought it would be too hard to get your Revit model into one of these...

Immaterial?

Check out this great post from Dave Baldacchino on Revit Room Materials.. A common cause of frustration when trying to deal with interior finishes.

Room Object Holding Pen

Ok, this is a really simple but useful tip which came to me today at work whilst having to make some amendments to a general arrangement layout. The layout in question has a number of room objects already set out and they all contain quite a lot of data such as name, number, department as well as a few custom parameters which I tend to use in all my projects. The plan view I was working in had a colour scheme applied to it to help identify the room functions.

The changes I wanted to make would mean pretty much destroying the layouts to reconfigure the layouts. Now as I’m sure some of you will of already found this process can be messy throwing up all sorts of error messages along the way regarding the room objects not being enclosed and so on. One way of dealing with this would be to delete the rooms being changed first, make the layout updates and place the rooms again from the drop down list of rooms in the project. A second way would be to drag the rooms outside into free space, live with the error messages about them not being enclosed, update the layout and drag the rooms back into the layout again. Both of these methods would work but somehow didn't seem satisfactory to me. I needed a visual method temporarily storing and organising the room objects whilst i made the updates. So I decided to make myself a Room Holding Pen. All I did was to create a simple boxed grid object to one side of the layout using Room Separation Lines. I then dragged the rooms into the pen, updated the layout and dragged the rooms back into the layout again.

Now i know this is a real simple thing but it really seemed to make good sense to me. By using the pen to hold the rooms whilst i worked on the layout it allowed me to keep in my mind all the spaces i needed to accommodate in the new layout. It also has the added benefit of keeping the Colour Scheme fills applied to the moved rooms which wouldn't happen if i simply dragged the rooms out into free space.

So, the next step for me was to try and figure out how i can make myself a simple family or template for the holding pen so i don't have to repeat this process every time i have to make a layout update. Don't get me wrong, it doesn't take long to draw one whenever you need one but i make a lot of layout updates and i hate drawing the same thing over and over. Given that you cant make room separation lines within a family i figured the only way to do this would be as follows:

Create the grid within a blank project using Room Separation Lines.

Grid-object-01

Group the room separation lines by selecting all the lines and hitting the create group icon. (giving it a suitable name)

Create-Group

Save the group to a library location via, Save As / Library / Group

image

Finally Load into into new projects using the Insert Tab / Load As Group.

image

One in the project you’ll need to drag the group from the browser into the model environment, placing it alongside your model.

image

Next drag your rooms from the model and into the Holding Pen.

image

Rearrange your layout and drag the rooms back into the model again.

Again, i know this is essentially a really simple tip and I'm sure some of you out there will have your own ways of doing the same thing but it is something which i found useful in my everyday workflow and as such I hope some of you will also find it useful too.

How to stop Revit floor slab edges from moving.

Some of you may already know this workaround as it does go back a few years but it’s something that I have just stumbled upon which would of saved me a lot of time on previous projects.


The symptoms.
  • Having groundhog day checking and double checking your slab setting out?
  • Wondering why one edge of the slab appears to of shifted whilst the other side remains in the same location?
  • Spending days wondering who is sabotaging your slab setting out and perhaps more puzzling why someone would be doing this?
  • Getting sick of having to edit the slab sketch and YET AGAIN lock it to a gridline?

 The problem:
Floor slabs sometimes feel the need to try and be helpful by shape shifting themselves when walls which are adjacent to their edges get moved. If the wall moves the slab edge moves. You can try any of the following methods to combat this behaviour to no avail. Pinning, locking sketch edges, locking dims, isolating on separate workset...All of which won’t work.

 The solution:
Simply put the slab(s) in a group and it will no longer be able to shape shift..
A very simple but very handy workaround. I’m guessing the same thing applies to roofs and ceilings although i haven't tested it on them yet.

AEC (UK) BIM Standards for Revit

Well, Its been a long time I know so I thought I better get back on board with updating the blog..

I wanted to spread the word about the AEC (UK) BIM standards for Revit which is freely available to download from www.aecuk.wordpress.com. This document should hopefully be of interest and of use to those of you out there who are starting to think about Revit standards within your office or your Revit projects. The standard covers a wide range of common issues including:

  • Project BIM Strategy
  • Collaborative BIM Data Sharing
  • Data Segregation
  • Modelling Methodology
  • File and Folder Naming
  • Presentation Styles 

The document is intended as a guide and is open to suggestions for improvements and modifications so please feel free leave feedback on the AEC website.
