AutoCAD 2008 Scale list and copying & pasting issue

This is more of an AutoCAD 2008 scale list issue. In some of our Acad 2008 files, copying and pasting even a simple line took more than 10 minutes. The copy operation was quick. But the pasting operation went on and on. This is because of a bug in Acad2008 scale list, which the service pack 1 didnt fix. If you are on subscription and you are on AutoCAD 2009 or up, you are good!
There is a scalelist popup menu in autocad (typically) at the lower right corner. 
Pressing this menu button shows the scale lists used in the drawing. Typically the number of list are less and shows like this:

However, autocad 2008 tries to bring in scalelist from any xrefs / blocks imported from other drawings and over a period of time the number of scale list can reach 1000s and makes the dwg really slow. The worst offender is the paste command (because acad is looking for ways to bring in MORE scale lists!!!!) The screws up with Revit whenever such a DWG file is inserted into Revit.
The scale list of the corrupted file looks like this:

This image filled up the whole screen.
To remove all these scalelist, you can use the "-SCALELISTEDIT" command. Typing the comand without the "-" crashes AutoCAD. Using the "-" forces the command to use the command line. You can follow the command line prompts to 'reset' the scale list. You will have to keep doing this if the DWG files gets corrupted again.

Moving a set of views from one sheet to another

Revit does not allow the same DWG view to be placed in more than one sheet. For this reason, when we want to move a set of views from one sheet to another, it does not let copy or cut and paste. It gives a “multiple instances of the same view in sheets not supported!”

One way to move the views, is to open the sheets category in the project browser

and just drag and drop the views to another sheet in the project browser or in the DWG area.

Referencing Detail and Referencing Sheet

Some of our government clients wants us to show the referencing sheet and detail numbers in the View title like:

Revit has this nice feature too!

Basically, these parameters show the sheet number and the detail number where this particular detail is referenced. This works perfect in most of the cases. However, sometimes the detail is referenced in more than one view (and so in different sheets). This can happen because of many reasons – dependent views or ‘show in – intersecting views’ parameter, etc.

In such cases, unfortunately, there are more than one referencing sheet that refer the detail in a drawing set. It looks like Revit shows the first sheet it comes across (per alphabetical order?) in the drawing set for this referencing sheet / detail parameter. It is read only and so, we cannot change it.

The workarounds is to manipulate the referencing sheet parameter by renaming / renumbering the sheet (not good) or to hide the unwanted callout / section / view tag category in the visibility graphics (not good again). (Just hiding the unwanted view tag using the View > Hide in view > elements option does NOT work!)

I think Autodesk should make this read only parameter a drop down menu where we could choose our preferred sheet from a list of available sheets…

If you like this option, please submit a support request with Autodesk.

Export to DWG from Revit issues

Even though Autodesk owns both AutoCAD and Revit, it is quite ironic that the export to CAD command does not work properly. There are so many issues outlined even in 2006, and most of them are still resolved.

The most irritating is the one related to the dimensions. When I export a sheet like:

with dimensions and if I choose any option other than the “overrides BYENTITY” in the CAD Export Format dialog box:

It results in out of scale dims like:

Not good.

Page setups are not similar in Revit and AutoCAD. So those don't get transferred too.

AutoCAD has a ‘nice’ printer called ‘None’ which has all the page sizes. Revit should retain the paper size from the title block and use the None printer while exporting sheets. This will not give a ‘printer missing’ error message in AutoCAD (when the DWG file is being opened), but still give the user an option to select an appropriate printer from the user’s network to print to the correct size.

Turn off grids and levels from linked Revit projects

We link a structural revit project into most of our revit projects. We typically develop the grid and after finalizing it, let our engineers maintain it.

We cannot show their grids in our views because, Revit does not allow the linked grid heads/extension to be tweaked. So, we typically copy/monitor the grids. However, when we tweak the grid heads, we see the linked grid head beneath:

One could go into the visibility graphics, and switch off the grids from the linked file on a view by view basis, but exploiting the workset option is more elegant.

Go to File menu > Manage links… and select the structural model and select ‘Reload From…”

and select the same linked structural file. Before pressing ‘open’, select the small arrow next to the ‘open’ button:

and select specify. Then press ‘open’. Revit shows the ‘Linking Worksets…” dialog box.

Select the ‘Shared Levels and grids’ workset and press ‘close’ and then Ok and again Ok. Now the ‘Shared Levels and grids’ workset from the linked file is closed and is NOT visible in any Revit view. Even though the linked grids are not visible, Revit still ‘monitors it!!!

If for some reason you want to see the structural grids, you can repeat the steps above to make them visible.
