Linked AutoCAD Files – Layers

Recently a question arose about removing layers globally from a linked AutoCAD file inside of Revit.  The user had went into Object Styles, Imported Objects Tab and then expanded the file for the .dwg file then proceeded to delete the desired subcategories for object styles.  This sounds like a completely legitimate way to go about this, with any Revit category if the subcategory is no longer needed then we simply delete them.  In the case of a linked AutoCAD file this is not the right way to go about this, the end result will delete the undesired layers but all of the arcs, lines, circles and text will remain in the file. I found this interesting and a bit of a surprise.  If those elements in the CAD file are queried  the will be un-associated to a layer therefore making it impossible to remove them out of the Revit file.  Instead select the CAD file and use the Delete Layers option, this will remove the layers AND all of the associated elements form the entire file.

Revit 2013 – Temporary Hide Category

In Revit 2013 View Templates went under a total reconstruct, they are much better in this release, or at least I think so.  One of the major changes was the ability to have views dependent on a view template, so if the view template changes all the views dependent on that template update automatically.  This is a feature that has been asked for many years and to a lot of people is long overdue.

I have one issue with this new feature, if a view is dependent on a view template, the Temporary Hide Category tool is no longer available.  I don’t know if this was by design or if this is an unwanted side effect of something else.  Either way I find this unfortunate, however I wouldn’t trade the new View Template changes to get it back.  If it does bother you the work around is to select all instances of an element then Temporary Hide Element in the view. However this may have to happen several times to accomplish what Temporary Hide Category would do for us.

 

Revit 2013 Print

So in Revit 2013 I noticed a small little change to the print setup dialog box.  This change is minor and doesn’t really affect any options but will be nice for clarification.  In 2012 and earlier when you changed the Zoom option to “Fit to page” the % size dialog didn’t change.  This could cause confusion where users thought it would fit to page but at 100% of the view.  Now in 2013 when you change to “Fit to page” the % size option disappears.  Not a big deal but I have had questions in the past on this and hopefully it will make things more clear.

 

Steering Wheel Features

While using the steering wheel command in Autodesk products, (I have only tested this with Revit and Navisworks), some of the features have additional options or tools associated with them. For those of you who haven’t used the steering wheel Shift+W will bring it up.

 

While in the Orbit feature of the steering wheel, the pivot can be changed on the fly by holding the CTRL key down.   Now you can locate the pivot point and then release the CTRL key and continue to orbit the model.

Before using the Zoom feature you can hold the Shift key down and it will take you into zoom window option instead of dynamic zoom.

While using the Look feture you can use the arrow keys to walk through the model, similar to W,A,S,D on first person video games. You can also use the Shift key before look to select a face of an element to focus on to.

With the Rewind tool not only can you see all of the previous zoom levels you were at but you can also fast forward to a position incase you rewound to far.

Last but no least you can also right click on the steering wheel and get a list of options, allowing a user to Fit everything to the window, Level the camera, etc.

 

Revit Basics – Linework Tool

The linework tool is found on the Modify tab, in the View panel.

 

With this tool a Revit user can override the graphical style of a model element, i.e. change something from a solid to a dashed or hidden line, or to make a line invisible all together.  Any line style in the project may be used, plus a few default out-of-the-box options.  Furthermore, each edge, side or line of an element may be independently overridden (so only one side of a wall, or one edge of a slab, etc). 

Once a line is overridden grips will appear at the ends of the lines.  These grips can be drug one way or another such that only part of the line is overridden.  The catch is that these grips will only appear when the linework tool is activated, and when the overridden line is selected.

 

What if more than one portion of a line is to be overridden?  Use the line work tool again and additional grips will appear that can now be drug independently from the first set.

  

One final question with this tool is how would one put the element back to its default style?  No, one would not have to delete the element and remodel it, and it is never a good idea to just draw lines over it.

 The answer is to use the linework tool once again, but instead of choosing a line style, choose “By Category” and click on the elements to be changed back to their default style. (It will be possible to select only overridden elements, even the ones that were made invisible).
