Path of Travel unable to treat door as obstacle

[richard.schmitt.sg]

all categories should be obstacles with this setting

I was testing workflows where we could set some doors (a door to a locked/secure area for example) to be considered obstacles by the Path of Travel tool.  The idea would be to set the door category as an obstacle, then hide any doors that are not to be considered obstacles.  The functionality of the Path of Travel tool implies it will route through the wall openings left by the hidden doors and treat the visible doors as obstacles.  In this screen capture you can see the settings as well as the path of travel line routing through a door that should have been considered an obstacle.

also, shouldn't it treat that sofa as an obstacle?

I think the tool was released immature. Expect it to be fixed/refined in a service pack or even the next version.

Analysis Zone in Plan Settings?  

...wait a minute! is there actually Model Geometry there to dodge? 

...I read that there must be at least 8" (20 cm) between obstacles. Maybe that's the issue.

Good thought, I set the "Bottom" to the 550 of the level (also I assume that is a typo in the dialog should say "Bottom (below the view's level)" since the field refuses negative inputs) and got the same result

[barthbradley]

if you do a Path from the upper left corner of the Room to the door, does it dodge the furniture?

Figured it out, the door family needs to have its 3D contents set to visible "When cut in Plan/RCP" for the path of travel to treat it as an obstacle, no 3D geometry in the view, not an obstacle

That's exactly where I was going went I asked if there was actual geometry.

@richard.schmitt.sg : FWIW, check out the different behavior I get by just toggling one checkbox in Route Analysis Settings.   All door shown here are OOTB. No modifications were made in the Families.  

[richard.schmitt.sg]

Exactly, for the basic doors in your example, the "door" itself is a 3d object, its swing line is not. For both settings, the path of travel navigates through opening and the swing representation.  When doors are set to obstacles, it will avoid the open door geometry.  For the overhead door, the opening is impassible because its geometry is "shut".  The workflow for the problem of having things like secure doors or locked doors as obstacles is to set the door category to be an obstacle, then ensure your locked doors are closed and your egress doors are open.

[barthbradley]

Not following you, @richard.schmitt.sg.  Are you saying that an "obstacle" is determined by the symbolic representation of a door swing?  

Both door families shown in my screenshots have solid geometry representing their door in a closed position.  This geometry is not visible in Plan/RCP.

[richard.schmitt.sg]

no, the obstacle has to be 3d, the orientation of that 3d geometry matters, because the regular door is "open" the path of travel can navigate through that door, on the overhead door, the geometry is "closed" and in your second image the path of travel does not navigate through it

I hope they will allow obstacle properties by instances, not categories.

Is there now a way to make a single item not an obstacle even if the group is considered an obstacle?

[Ryan_GormanKT36T]

So far it seems like the only way to make a single item an obstacle is by 

• Hide in View
• Change its Family Category

These are good solutions but will not be possible in all situations.

In the interim while we wait for an official solution from Autodesk, I managed to successfully created a family that will not allow routing through a door or opening. It works with a nested instance of the one way indicator in the family but rotated in the opposite direction, therefore preventing a path traversing from either side.
