Corner window anomoly

[Keith_Wilkinson]

sorry if this has been raised before - I came across the issue when creating a corner screen for a project and then found the same issue with the OOTB corner window family...

When placed in a legend, it appears with an additional outline that looks like it might be an opening but it doesn't tally with the void within the family that creates the actual opening.

Anyone else come across this and do you know what the cause is and how to get rid of it?

That looks like it might just be the host wall that is a part of the family.  Go to visibility/graphics and turn off walls in that view and see if it goes away.

Correct for 10 points!  Turning off walls in VG removes the offending item.

However the question now is why is it there in the first place?

[Keith_Wilkinson]

Sorry but the post above is not 'the solution' it simply highlights what the problem is.

I don't want to know how to 'hide' the problem I want to know how to fix it.

If it is a bug in Revit then tell me.

I have unselected the post above as being 'the solution' to avoid any confusion.

Your window must be a wall-hosted family, which explains why there is a wall.  In the legend view, you can choose to have the plan, elevation, or side view.  In the plan and side view, depending on the family, it might be useful to have a generic host element (the wall, in this case) visible in order to accurately convey information about the family.  Since it appears that you don't need that host element as a reference, you can turn it off in your view.  This is not a bug, it is the intended result.  If you want to avoid it in the future, you can set up a view template for your legends that turns off the wall category by default.

Also, the reason my previous response was marked as a solution is because it answered your original question.  Just because you had a follow-up question doesn't make the previous answer any less of a solution to your question.  Please re-mark the answer as the solution.

If that is the case then why does the same issue not appear with a standard window - only thus far (as far as I'm aware) with a corner window when an void is used rather than an opening.

For reference my original question was 'do you know what the cause is and how to get rid of it?'.  I didn't ask how to hide it.  In my legend for instance I may have other elements fo wall that i do wish to keep visible so your VG override wouldn't work.  And as the rogue element isn't individually selectable you can't use override in view.  Furthermore if this intentional behaviour surely it would be possible to adjust the size of the element as it only become visible when the family is made quite small - so sorry but I'm not buying it that this is intentional behaviour.

With regards to marking the solution, if you don't mind I'll mark it when I feel a suitable solution has been given.  As yet I'm not sure it has but I want to look into your second post in more detail before I come to any further conclusions on it.

For anyone that wants a look I've attached a file with the issue shown on the door legend.

A bit more playing around with this and it turns out it affects every window less than about 915mm across.  When you get smaller than this this 'host element' appears, over which you have no control of size, can't be dimensioned or independently selected and hidden.

I fail to see how this can possibly be an 'intended result' and it appears to me to be a bug.  If it met any of the above criteria I would probably argue differently but the sheer lack of control indicates to me that this is unintended behaviour.

As Ross has pointed out one option is to turn off walls in your legend but this is a bit like using a sledgehammer to crack a nut and really isn't useful if you need to show other wall elements in the same legend.

A better solution would, IMO, be to use 'Phase based' legends where A) the issue doesn't appear B) you have significantly more control over how the familiies display.

Neither solution is ideal but until some general improvements are made to the Legend function of Revit I think this is as good as it gets.

Cheers

Ross, it think it might also be helpful for many users if you can explain how to create a 'side view' using a Revit legend - I'm sure many would find this useful.
