Revision Tag Fails to Display a Value

Using the latest build of Revit Architecture (20071109_2345) Revision tags have been failing to display a value. We have not determined the cause but at this time it looks "buggish". In the meantime a work around.

  • Place the revision cloud
  • If no revision value is supplied in properties (or in a tag if placed)
  • Edit menu > Cut to Clipboard (the problem cloud)
  • Edit menu > Paste Aligned > Same Place ( or Current view)
  • Value should display now in properties and a tag when placed

Autodesk Responded with this:
This appears to be the result of an interaction between the Annotation Crop and the Revision numbering mechanism. This has been reported in a few cases before this. I will log this problem and you will be updated on the progress of this.

The workaround for this is to go to the View Properties for the view with the Tag in it and turn off Annotation Crop. Insert your Revision Tag. Your Tag should now be visible but your annotation is now visiable every where. Go back into the View Properties and turn Annotation Crop back on. This should fix your problem.

"Tip of the year 2007" fade out in elevation from Revit model

Joe Zhou from our Hong Kong office says - "this tip provided by Kei from Autodesk helped us and is so good I want to let everyone know about it"

This tip is useful especially in Scheme Design stage when you want to create fade out effect in elevation sheet. Here is the procedure to achieve 'half toning' far side elevation view overlapped on regular elevation view both layout on same sheet

Create two elevation views:

1 - Farside clip just about enough width (does not need to be accurate) that will appear on specified elevation view angle.

2 - Foreside with thin layer of depth clip, but having overall width for ground surface. (This is for better performance + not to show farside objects)

3 - Place them on sheet in order: Place farside first

4 - Then, place foreside - when placing this view, you should be getting center of gravity ‘cross reference lines’ for accurate location (placement order matters for foreground/background. See elevation image above, farside is overlapped by foreside without trimming at right edge.)

If you happen to place foreside first then the farside, delete foreside then replace it.

Did something in your project disappear?

Most of HOK CAD Solutions are home grown, but here is a great checklist from David Duarte Revit Beginners blog.

http://revitbeginners.blogspot.com/2007_01_01_archive.html

1. First, check to see if it is still visible in other views.
2. Check Visibility/Graphics. Is the object category (and subcategories) ON?
3. Check Visibility/Graphics. Is the linestyle set to Override?
4. Check Visibility/Graphics. Is the detail level set to By View?
5. Check Visibility/Graphics. Are all the worksets ON?
6. Check Visibility/Graphics. Are all the filters ON?
7. Check Visibility/Graphics. If the object is in a linked file check Revit Links.
8. Check Visibility/Graphics. Check each design option.
9. Try changing phase and phase filter in View Properties (VP).
10. Try changing the detail level of the view.
11. Are all your worksets opened? (it may be hiding in a closed workset).
12. Check View Range in View Properties (VP).
13. Check for Plan Regions if in a floor plan view.
14. The object may have been moved to a new elevation.
15. Check Crop Region and Far Clip settings in View Properties (VP).
16. Set your view to wireframe. It may be hiding behind a filled region or other object.
17. Select the Linework tool (set to By Category) and see if it wasn't hidden with this tool. It would be very benefitial if one could toggle on/off the use of the linework tool in a view.
18. If the problem is with a family file open the family and check the visibility of the elements.

"If you can't find it by now it was probably deleted!"

Disappearing Revit crop region

Bart van Vliet/SF says: "When snapping to the edge of walls, ceilings, etc to define the crop region , sometimes the lines disappear. I can’t figure out how to allocate a line type to the crop region. The only solution I can think of is to stretch the crop region beyond the limits of the elevation, and then create a masking region of two closed loop lines, of which the interior has the heavy line and the exterior lies beyond the extends of the crop region."

> David Nilsson/ATL solution: The two loop masking region is the solution I use. You can create a detail component with the masking region already set up to speed the process up a little, but as far as I know that’s the only way to get the profile lines to appear in the traditional manner. I’d love to find out that I’m wrong.

>> Kevin Parks/ATL responds: I use this same technique, but as far as the crop region is concerned, pull the region off of the edge of the wall just a little and the line will not hide. Revit wants to snap to the wall face and covers up the increased line thickness. So, the solution is to pull the crop region back off the face of the wall and the line will show up again. Make sure when you do this that your thin lines button is turned off so your line thickness shows up.

>>>Bart: The best option I have seen is the one I started with: puling the crop region off of the walls, ceiling and floor and creating a masking region with a heavy line outlining the face of wall, ceiling and slab and another line outside the crop region. Still open for suggestions, as it is quite a bit of work.

Ed - "Revit Wish List" then!
