Open Web Joists - need them to look dashed in plan

[lzaras]

We've got some existing joists that are being Demolished. In our demolition plan, we need these joists to show as a bolder linetype and dashed.

If the joists are of "the right" length, they are showing (almost) as we wish. If they are of "the wrong" length, it shows as a solid line.

I think the problem is with all the panels/joist spaces. I tried editing the joist family but haven't had luck, yet. Anybody know where I should be looking? What I should be editing?

You should be able to make those changes in the setting menu.

-Objest Styles
-Model Objects
-Structural Framing

We still have existing joists - not being demolished - and new joists in this model. So I don't necessarily want to change the "look" of all the joists in the project. Just the ones being demolished... and only in the Demolition Plans.

... or am I missing something?

Have you tried going to Settings > Phases > Graphic Overrides > set the override for demolished objects. You can do that for either cut or surface to be as you want (color, line pattern, surface pattern, line weight, etc...)

yes. That's how it's set up right now... The thing is, it's not consistent. Depending on the length of the joist, sometimes it looks dashed, sometimes it looks solid. There are more items in the joist family that are showing in the plan... I guess I just want a single, dashed line to show.

I have had issues with this also, I recommend using a Filter override for the demolished beams to sort out the issue.

This is a bug in the families. (Since RS2 at least) The OOTB families have extra model lines that need to be turned off. Once you turn off their visibility the coarse view line type will display correctly. This is true for all OOTB joist families...

[Jshaver]

I neglected to mention there are also a couple of other issues with these OOTB families. By default they are using a symbolic line to represent the joist in coarse view. That means whenever you have a sloped member the joist will dissapear in plan... A simple correction is to recreate the symbolic line as a model line setting the visibility so that its only visible in coarse view. This will allow the line to be present when the member is sloped. Another possible approach would be to set the symolic line by project and use a filter to control the line style (I have not tested this)

There is a lack of control for independant joist seat lenghts. This can be fixed by adding an additional parameter for the second side (and renaming the original).

The formulas used within the OOTB family crash when trying to create a joist smaller than a 2-panel array. Updating these formulae should allow for shorter joists.

Due to all the issues (and the issue listed in my previous post with these families I would recommend building them correctly from scratch. According to the joist catalogs I have seen, the layout for the webs are not entirely accurate anyway. For example the LH series joist does not include a vertical member within the panel. These are the kinds of things that we need to have in our model for clash detection when attempting interdisciplinary coordination.

Thanks you Jshaver... from both of your posts, it seems that you understand my situation completely. The OOTB joist family has so much embedded in it, I spent too much time already trying to dig deep enough into the family to "fix" it for my project - but evidently didn't dig deep enough to make it work. Nor do I have the time right now to develop a working joist before my project is due out. I'm afraid my work around is going to be to make all the demolished joists invisible in plan and draw dashed detail lines back in place. Messy solution and I'm still looking for other options. But if it comes down to it, that may be my solution.
