Isolating your annotations

Given the number of interior elevations - types of elevations need to be isolated. As elevations are not view-dependant, there is a trick to isolate the categories you want.

To isolate annotations- use filters in the visibility graphics for a view. Select a filter the uncheck the box under the View column. This will hide anything matching the filter.

The default elevation style is now INTERIOR-INTR. There is also now an INTERIOR-ARCH. This controls the visibility of the system families symbols (the circles for the elevations as an example).

When applying VIEW TEMPLATES consider whether you want to apply the V/G Overrides Filters - any pre-existing filters may be overwritten if this is checked- which is OK if that is what needs to be done to correct the view.

Revit Floor patterns and materials

Kristine and I worked this out a little farther...

Set the offset height when creating a new floor to 1/4" (element properties in the toolbar- not the option bar) and it will remain 'sticky' - i.e. upon finishing the floor, creating a new floor will retain that value. This offset allows shading of the materials to show when the plan is "viewed in shade mode with edges"..
Different colors for the shading and surface patterns drive how the element displays- particularly the hidden line and shaded views. If the floors are co-planar (i.e. the offset is not set) materials will not tag correctly in plan(not even with tabbing.) and solid patterns get lost. (Note the solid hatch pattern + color will override the shading color!)
Sheets can be created in color, and printed in either color or grayscale to easily identify layouts of materials on the floors- no more cryptic hatches!

Maybe we should do a lunch and learn for this or a Revit session? The process has been revised (see below!)
Process for creating floor patterns for material tagging (revised):
  • Set up your materials first !
    • FINISHES-INTERIOR-T-01-TERAZZO-01 (Dashes - no gaps please, all caps too!)
    • Use Zero padding in the event more than 9 versions of the material show up. ("01" instead of "1")
    • Sync to central!
  • Make sure the workset you are working on ins OPENED-
    • via the Collaborate tab, select the worksets icon,
    • open the workset(s) you need to work with.
  • Make sure you are on the workset in the collaborate tab.
  • Then either use Floor types or split faces:

    • FLOOR TYPES:Set up floor types- Useful where mortar set beds or other recessed areas like showers could become an issue. Separate from the main floor but can be joined to the main floor . Recessed areas of the floor can be tagged using an elevation tag to show the top of the floor and the bottom of the floor relative to the level- so if the floor is slightly raised (i.e. 1/4") and requires a 2" deep bed for mortar setting or shower drainage- it will show it.
      • Use FINISHES-INTERIOR-[T-01-brief description] for the floor types
      • Floor types should have a layer of the material representing the thickness of that material and any set beds. the materials should typically be set to finish2 and can be as simple as one layer thick
    • SPLIT FACE: start splitting out areas for finishes. This is fast but has a huge drawback - if the floor is deleted all information is lost. Sketches for splitfaces can be stored in groups, if they touch incorrectly or touch a shaft or other joined element they will cause an error.
  • Sketch out the different materials (note Sketch lines cannot intersect )
  • FLOOR HOSTED FAMILIES: can be created to utilize materials and create repetitive patterns, constrained to rules, snap to increments ( like VCT inlays) etc.

Using Revit with GlobalSCAPE WAFS

If you have been having trouble with linking, UNC paths and drive mapping this states the issues quite nicely and has a work aorund that may work:

Using Revit with GlobalSCAPE WAFS
Central File Access
A single adjustment must be made on user workstations for users that will be working on work-shared Revit models being replicated by the WAFS system. The modification requires the creation of a new drive letter mapping using the Windows SUBST command. When Revit creates a Central file, it stores the path of the Central file within the Central file and associated local files. This path is used by the Revit workstations in conjunction with the local copies of the Central file to identify where the Central file resides for actions such as Save to Central, Reload Latest, and borrowing.

When replicating Central files via the WAFS system, the Central files will be located on different file
servers at each site. Thus, the UNC path will be different at each site and will result in Revit failing to locate the Central file when working in the work-shared mode. Supposing there are 2 offices, users at Office A will access a shared drive on FileServerA and users at Office B will access a shared driver on
FileServerB. If a user at Office A creates a new Central file, the Central file will internally store a UNC path with \\fileservera\Revit Projects. When a user at Office B accesses the file, which has been replicated by WAFS to FileServerB, Revit will expect to see a UNC of \\fileserverb\Revit Projects and will issue a warning that the Central file has been relocated.

Rounding errors can be a problem which is why the smallest tolerance allowed is used. Typically when EQ./EQ. is used small fractions are created.

Here is a trick to help cleanup the dimensions that aren't exact-

  • Create a tolerance dimension style if it doesn't already exist. It should be labeled similarly to the original style- but suffixed similarly to "(1/8 TOL)". This is a *special* temporary dimension which reflects the tolerance bound within a particular dimension style(1/8" typically).
  • If needed- create a continuous dimension string (Try to avoid individual dimensions if you can). You can select entire walls utilizing dimension options to define the 'how-to" for these strings and edit the witness lines as needed.
  • Make a copy of the dimension string you want to correct.
  • Change the copied dimension string to the tolerance style.
  • The alternate string will show a rounded value closer to the correct tolerance:

  • Cleanup by selecting the objects you want to adjust.
  • Start from established references like gridlines you know are accurate.
    • To change a dimension (From Revit Help):
    • Select a component that the dimension references.
    • Click the dimension value.
      If the dimension is locked, the lock control appears next to it. Click the lock control to unlock the dimension so you can change it.
    • In the edit box, type a new value for the dimension and press ENTER.
  • Rounding cannot be used in the dimensions as rounding errors will occur.
  • If all dimensions within a string are an accurate representation of values rounding errors should not occur.
