Has anyone successfully applied a masking region to a section head family so that a mask is applied to all object "below" the placed family? When I create one it does this but it also masks out the items within the section head or the circle of the section head.....

Havent tried to do that in particular but opaque text does about the same thing. Otherwise you could try playing with display and draw order. If the options arent available while working in the section view you may need to draw the items from front to back. It seems that the first item drawn ends up behind with each progressing item drawn in front. HTH Nick

Nick, Thanks - tried that and still cannot get the masking region within the family to not mask out the family once placed in the project. On my structural drawings I do not like clutter or anything going thru text. In Acad, I created a dynamic block with a wipeout and played around with color and transparency and all of that and got it to work. I must say Revit has beaten me up on this one... II still can't believe with all the users and members of this forum that I only received one reply on this. Any further help would be greatly appreciated, thanks Patrick

This forum is actually a little slower than Augi http://forums.augi.com/forumdisplay.php?f=93 Ive esepecially noticed the difference since around november of last year. Dont know if everybody went on vacation, got to busy or what. But you can always try posting on Augi and see what you get there. Sometimes people think the question is to easy and just pass it by. You are most likely to get a reply if you can figure out when the high end users (Steve Stafford, Mr Spot, etc) are on. Post around that time and they are more likey to answer... Nick

Hi, Try using another lineweight other than Section Marks from your Type Selector while doing the masking. I just tried it now and it works.

I just tried changing the masking lines and I still get the same result. If you load the attached family you'll see what I mean. Let me describe the steps I am taking: I open up an existing section head family. I apply a circular masking region (extents match the diameter of the section head circle) I make the lines of the masking region to thin lines, (I have also tried invisible lines with the same result) and I finish sketch. I then save as and load into my project. What I would like to have as a result is for the section head (circle area only) is for it to mask objects in the model (plan views, sections, elevations) but not the lines making up the section head family (which is what is currently happening) Thanks again for the help! Patrick

Try using 2 half circle masking regions. I just cant figure out how to not have them rotate with the section. Somehow the line thats already in the family doesnt rotate but everything else does. So if you create a half circle masking region on the out of the box family it works fine horizontally but vertically the center line disappears. I guess you could always make 2 different heads and une one for vertical and the other for horizontaland everyother angle that you may need.... You could set the half circle masking regions up with a parameter to rotate them and then just create a new type for each angle. That is unless you an figure out how to get the linework to not rotate. In which case I would like to know also.  HTH Nick

Nick, Okay so I tried what you suggested and I can't even get that to work...how did you implement the masked regions? I also just tried from scratch starting with the masking region as the first element drawn and it still masks the line which doesn't rotate. Thanks...I'll keep trying. Patrick

See the attached family and image. For some reason the half circles are faciting, something to look into later. From the image you can see what happens with the masking regions when the section rotates. You would have to add a parameter to rotate them. Nick

I thought if the line in the masked region closing the half circle was set to invisible lines it wouldn't show up when loaded and placed at any angle, but it ends up masking the entire circle including the line which never rotates. I cannot just change the labels in the family to be opaque, because when the text string gets longer the text will mask the family objects, similar to what the masking region has been doing for me. In the family editor (for this family) it won't let me set elements behind or in front of one another.

Unfortunatly the send to back/ bring to front is only avaiable with certain objects in certain views. So youll just have to deal with a parameter and 2 masking regions. There are a bunch of things that Revit doesnt do well or even at all. I think we all get spoiled by what it does do and then "logically" think it should do x. The reality is Revit will never do everything that you want it to and there will always be work arounds.... Nick

Hi, Still with the masking dilemma? The closest you can get right now is to do a circular masking in your section head (as what you have been doing)and have the detail number with the "underline" option checked (just to separate the det.no. to the sht.no., in a way.) You might need to create a different text type for that purpose. Though the dividing line seems short, it rotates with your section head.

Okay, so I went one step further with your idea about the full circle region and underline text. First I added the circle region. Then I added text with a series of underscores to make the line from one side of the circle to the other...works like a charm! Thanks for the brain-storming! Attached is the working masked family placed at any angle... I will be sending this as a wishlist item - the ability to mask the section head. Thanks!

Little akward but at least it works. Thats what I meant by workarounds. Theres always a way just not nessisarily the logical one Nick
