Revit 2010 Decal Path

If your path is too long to a specific decal image it will not render. You can workaround this by adding the path of your image to the Options-Rendering-Additional..Paths.

Autodesk is aware of this issue....

Rise and Run Roof Slope Tag

Thank you Autodesk for adding one of my wishlist items from way back! This may be a small thing but it's important to residential designers. Thanks again!

I found this on David Duarte's blog Revit Beginners...(Thanks David)

Go to Annotate... Spot Slope... and you might notice that Revit has a new slope annotation that works in plan and elevation view. (choose an arrow or triangle symbol from the options bar)

Now try annotating a roof slope with a spot annotation triangle and you might notice something peculiar. Maybe your roof is 6:12 but the annotation read 4:12. Why the error? Because Revit is annotating the Hip not the face of the roof...Try hitting the tab key while floating over the roof edge and you'll see that the slope tag can report the slope of the hip or the face. The tool just happens to default to reporting the hip first.


This tool does not yet work on ramps or railings.

Tag Box Size Relative to Contents

Is it possible to have a tag's box size expand with the contents?

For example, if a room is numbered '1' it doesn't need a big box, but if it's numbered '1001' it does. (This is applicable to all tags really.)

The answer is no, it does not expand automatically. You will need to make a few different types that have different sized boxes.

Curtain Wall Corner Mullions

Curtain Wall Corner Mullions are preloaded in the default template. You have the following choices of shapes: (see image)

Quad
L
V
Trapezoid

You can make more types by editing the properties. (see image) You can edit material, thickness and general size.
You cannot make a custom profile for corners like you can for non-corner mullions.
If you would like a custom corner you will be best to make it out of a structural column family.
If you are missing the corner mullion families from your project file (maybe they have been purged) do the following.
-Project Browser
-Families
-Curtain Wall Mullions
-Right Click on desired heading
-Choose New Type
Corner mullion size can be adjusted in their Type Properties.
Also, the corner can be non-perpendicular and the corner mullions will adjust.

Curtain Wall - Butt Joint Corners

Butt joints at corners can be done the following ways…

Option A

1. Make a new curtain wall panel using the curtain wall panel template
2. Offset the geometry on one side.
3. Save and load the family into your project
4. Make a Curtain Wall Style with Vertical Mullion, Border 2 Type, None
5. Draw the curtain walls on the corner. The wall endpoints will be lined up but the glass will appear to be overlapping by an inch or so.
6. TAB until you can select the panel.
7. Replace the panel with you corner panel.


Option B

1. Draw the curtain walls on the corner. The wall endpoints will be lined up but the glass will appear to be overlapping by an inch or so.
2. TAB until you can select the panel.
3. Edit in-place
4. Stretch the glass panel back by 1”
5. Finish


Option C

1. Draw the curtain walls on the corner. The wall endpoints will be lined up but the glass will appear to be overlapping by an inch or so.
2. TAB until you can select the panel.
3. Turn off the panel’s visibility
4. Draw a wall style which is the thickness of the glass panel and has the material ‘glass’.

Any of these choices are a pain. This is one of the workarounds I would like to see addressed...

Lineweights Bug and Workaround


We have noticed that there is a discrepancy in the lineweights between Titleblocks and Projects. It seems that the Titleblock Family's lineweights, although set to the number, appear and print thinner. Autodesk has confirmed that this is an error and plan on fixing it in a future release.


For now you will need to bump your lineweights up (set to a higher number) on your Titleblock Family in order to match the lines on your sheet.

Database Link in Revit

We've been waiting for this one for a long time...

RDB Link Tool for Revit Family
Technology Preview (COMING SOON)
Overview

The RDBLink tool allows the user to export data from the elements in a Revit project and maintain relationships against data that exists outside of Revit. The tool allows for both import and export of the project data and will allow the user to make changes on the database side that affect the data within the project once imported. Also, during subsequent exports of the data to the same database, only data from the project will be affected, so any new fields or tables added to the database for your own purposes will remain intact along side the newly exported data. The RDBLink import tool provides a grid view of the data to allow the user to make any final edits before import. This grid control also allows the user to create Revit Shared Parameters which will add new fields for those parameters to the database in the related tables. Changes to these new fields within the database will update these Revit Shared Parameters upon future imports.

Elevations and Phases

Elevation markers disappear in different Phases. How do you coordinate the extents and views of these different phases? You can address this by doing the following:

1. Select the Elevation Marker, Cut and Paste Aligned-Same Place. You would do this into the view with the Phase set as desired. The copied Elevation Marker will be in the same place but on the desired Phase.

2. Make a Scope Box. You can drag the extents of the Scope Box to determine where Grids and Levels start and stop. Click on the Grids and Levels, Element Properties, choose the Scope Box you just made. Scope Boxes also have properties that allow you to control the view it's visible in.

3. Organize your Browser. This can also be done by adding a parameter to the views.

Room Number Intelligence

More and more I am seeing the need for room number intelligence or awareness. I am not alone on this, many of our clients are asking this.

Yes, I can schedule what level a ceiling is on but what about what room it's in? You can do this a little bit with the doors so we know that it's possible. What room is that patient bed, furniture, or light etc. in? It would be nice to then schedule 'by room'. For instance, Room 101 contains: patient bed X, X number of lights.

Please comment...

Tagging Ceiling Heights in Room Schedules

This can't be done automatically.

Here are a couple of workarounds...

1. From release 2009 and on you can do the following:

Settings-Area and Volume Computations-Calculate Volumes
Make sure the Room object is bounded to the ceiling.
Add a Calculated Value to the Room Schedule using the following info:
Name: Ceiling Height, Type: Length, Formula: Volume/Area
Please note that this workaround only works where the Room and Ceiling are the same shape. The ceiling must be flat.

2. Pre 2009, ie.2008 has another workflow. You may even choose do this in all releases because of the complications of the workaround mentioned above.

Make a Shared Parameter called Ceiling Height
Apply this to the Room Object in the Project file as well as the Room Tag
Make a duplicate of your ceiling plan.
Tag all ceilings showing Height Offset from Level
Tag all Rooms
Now that you can see the actual ceiling height you will be able to manually update the Shared Parameter 'ceiling height' in the Room Tags.
This will keep a coordinated Room Schedule, Tags with the ceiling height.

Can't Edit Hatch in Family

Many times you will insert a Family into Revit which has hatch on it. You will not be able to edit the location or orientation of that hatch while it is in the Project. You would need to open the Family, adjust the hatch, then reload it back in.

AutoCAD Pline Widths in Revit

You want to Import or link an AutoCAD file with plines representing walls. The plines are set to the actual thickness of the wall. When this is imported into Revit the plines lose their thickness.

Changing the Revit lineweight is not the greatest solution because the lines change thickness based on scale. Also, you would have to do some calculations to get the corresponding width right.

You would be best to make the change in AutoCAD before you bring the file in. To that end I've attached a lsp routine which will convert plines to mlines with the corresponding width. You might want to add another string of code which explodes the mlines into lines because mlines don't come into Revit either.

Here's the thread where I found the lsp file written by Joe Burke...
(note: this code leaves out closed segments, you will need to change the plines to 'open'.)

http://discussion.autodesk.com/forums/thread.jspa?messageID=1163735

Here's a cut and paste of the code...

;;;thanks Joe Burke
; CHANGE LINE/PLINE TO MLINE
(defun c:lml ()

;returns list associated with a DXF code
;arguments key: DXF code, alist: object data list
(defun massoc (key alist / x nlist)
(foreach x alist
(if (eq key (car x))
(setq nlist (cons (cdr x) nlist))
)
)
(reverse nlist)
) ;end

;(setq s (ssget))
(setq s (ssget '((0 . "LINE,LWPOLYLINE"))))
(setq teller 0)
(repeat (sslength s)
(setq en (ssname s teller))
(setq ent (entget en))
(if (= "LINE" (cdr (assoc 0 ent)))
(setq PtLst (list (cdr (assoc 10 ent)) (cdr (assoc 11 ent))))
) ;if
(if (= "LWPOLYLINE" (cdr (assoc 0 ent)))
(setq PtLst (massoc 10 ent))

(setq teller (1+ teller))
) ;repeat

Conditional Formatting Trick...

I just saw this trick on Steve Stafford's blog...

When you are creating/editing a schedule and select a value that can be formatted, like Area or a Number value for example press the ALT & N keys in the formatting tab. You will then be able to select a range or do other snazzy things.

Shared Parameters File

Do I need to send it with my Project file?
Will all of the parameters give errors if it is deleted or moved?

The simple answer is no.

Deleting or moving the actual Shared Parameters File does not cause any immediate errors, unless you try to make a parameter from it again. The information from that file is saved with the main Project rvt file. That means that you do not need to send it with a Project file. If the users at the other end want to edit, add or use it they will either need to get yours or make an exact copy themselves.

Here's a little more explanation...

This goes to show just how good Steve Stafford of Revit OpEd is. This is a 2005 article from his blog (which he wrote on a Sunday).

"...deleting the shared parameter from the shared parameter file (there is no link to the shared parameter file) doesn't directly affect a family or project that already uses it. Only when you remove it from a family or project will it affect the existence of data. Also you won't be able to assign or use the parameter again after it is deleted, since a new parameter by the same name is unique in the world as far as Revit is concerned. "

Select All Instances Tool Dangerous

I would recommend that all new users not use the Select All Instances tool. If the tool was 'Select All Instances in View', then fine but not as it is. Why? If you pick a piece of text in a drafting view and then use 'Select All Instances' all text of that type will be selected. If you then delete, it's all gone in every view. This holds true for walls, doors and everything.
