Revit Basics – The Filter Button

Leave a reply

This is an excerpt from an article that I wrote for AUGIWorld.

When multiple items are selected, it is a common practice to use the Filter option that appears on the Ribbon’s Modify/Multi-Select Contextual Tab only when multiple items are selected.

Alternately, one might use a keyboard shortcut such as “FF” to activate the filter.  One may have even noticed that there is a tiny filter symbol at the bottom right of the screen, on the Status Bar.  What is lesser known is that clicking on this symbol will activate the filter command.

Linework Tool and Underlay

Leave a reply

This is a tip that I have been showing for years and I was reminded of it today while training a student.  The tip involves the use of the Linework tool along with underlay while in plan views.  This student was asking how to display the roof overhang in plan and wondered if it could be displayed as hidden lines.  The first, most CAD-like, response was to simply draw hidden lines where these elements were.   I explained how that is an option, but what happens when the roof changes or moves?  Now someone would have to go back and adjust the lines to match the changes.  If Revit could do that automatically, that would be a better solution.  My suggestion was to turn on the underlay so that the elements in question could be seen.

To do this, set the underlay to the current level, and the set the plan orientation to Reflected Ceiling Plan.  Then, on the Modify tab in the View panel, select the Linework command and set the line style to <Overhead>.  Now select the lines that need to be displayed in the plan.  Once that is done go back and change the Underlay to None and the lines that had been changed via the Linework tool will still be displayed.

 

 

If you decide later that the lines are no longer needed DO NOT DELETE the lines, this will delete the physical element.  Instead, again use the Linework took and with the linestyle <By Category> and select the lines.  The lines will go back to their default display, or not displayed if the were changed as an underlay.

 

Continuous Overhanging Gable Roof

A question came up in the Linkd In Group for Club Revit  about creating a single roof with a gable end that would basically go underneath itself to attach back to a wall.  I thought I would do a post to my simple response, so that I can get a bit more detailed in the explanation.

The first step is to create a roof by footprint, personally I would use the Pick Walls tool for this situation.  Uncheck the defines slope option to get the gable ends as needed.  Finish the roof when done

 

 

 

 

 

 

 

 

This doesn’t alone dosen’t get the small gable end roof to come back under itself to attach to the wall.  It also doesn’t automatically take the walls up to the roof.

 

 

 

 

 

 

 

 

 

 

 

 

I chose to model another wall above the other and make it the full length of the roof, and then attach that wall to the roof.  This way I have something to Join the roof to.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The next step is to use the Roof Join/Unjoin command located on the Geometry panel of the Modify Tab on the ribbon.

 

 

 

 

Pick on the edge of the roof that needs to Join to the wall and then pick on the wall.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This will be the completed result.  Now just go in and add all the detail like soffits, fascias and gutters.

While doing some training today I had a user find a bug in the program that I forgot about.  It has to deal with the “Hide at scales coarser than” value for views.  When a view is not a live view but references another view it doesn’t obey the “Hide at scales coarser than” rules, it will always display. Something to be aware next time you are trying to troubleshoot this issue.

 

 

Show Walls Below Roof

Leave a reply

After my post about show hidden lines someone had contacted me and had a concern that this tool didn’t work for what he needed.  In this particular case the person was talking about showing walls below the roof.  He had went through and used the show hidden lines tool and some of the walls displayed hidden while other didn’t.  The underlay value had been set to display the floor below the roof, some of the walls remained half-toned and others displayed hidden. Once the underlay was turned off (see note below on underlay) the walls that weren’t showing hidden disappeared.  In this case there were actually different issues that were causing the walls not to display hidden.  One of the issues was with the view range settings.  The view range bottom and depth were set to to current level at 0″ so that nothing below the view could be seen, so once the underlay was removed the hidden lines didn’t display.   The view range was changed to be -1″ below the current level, for both the depth and bottom, and then the hidden lines appeared.  The other issue was the fact that some of the walls had been attached to the roof, this allowed the show hidden lines to work with out adusting the view range.

NOTE: Underlay displays another slice of the model under the current plan view. That slice of the model can be from above or below the current level. The underlay appears dimmed and is visible even in hidden line visual style.  The orientation can either be a Plan or RCP .
