Family in plan view not showing for Coarse or Medium, Fine only.

[sdonahay]

When the attached family is loaded into a project it shows in all views as expected except the plan view.

In the plan view only with visibility level set to Fine will the family show up. Coarse and Medium settings the family disappears. I have the objects in the family set to what I believe is correct.

The family looks fine from my end. Check and see if you have the latest patch.

Check the Visibility Inside the family User interface select the object>from Visibility icon check it had check for Coarser and Medium. Hope this method help you and if u need and support with ur problem contact with me in comments.

Uncheck Use Annotation Scale.

[sdonahay]

I did that. That is what the one pic shows.

[sdonahay]

This is what i have installed.

Unchecking in the project will make it show as you stated. If I uncheck \ the parameter in the family and load it into the project fresh it still does not show unless I check the box. So whatever the family is set to....checked or unchecked it has to be unchecked or checked in the family to show up in plan view with LOD set to coarse or medium so it does not solve the issue.

It must have something to do with the Pipe Accessory category. I saved it as a Mechanical category and no issues.

Save it back to Pipe Accessory and problem is back.

Do you mind share the file with that family loaded?

[sdonahay]

Can not load Project. Company policy. The family is attached to the original post.

[syman2000]

Yea I think the piping accessories is hard coded to hide for medium or course with Mechanical setup. Your option probably change the pipe accessories to fine in the graphic override.

I loaded it into a sample MEP project with the same results. I also noticed all the conduit runs did the same thing so I think the attached pipe acc follows the same rules. I have other pipe acc families that I made that do not do this. So i am a lose as to what is going on.

When I load your sample to Architectural template, it shows up fine for coarse, medium and fine. Autodesk probably hardcode the mechanical template to read these object to only show up fine. I've check old post and they all have similar issue to yours.

Pipe accessories and fittings normally show the 3D elements in fine detail. The problem here is that the 2D representation that takes the place of the 3D elements when the detail level is lowered is not showing. The model lines (2D representation) in the family are not controlled  by the Use Annotation Scale Parameter which is why nothing shows when that parameter is checked, which turns off the 3D elements even though in the family that parameter is not assigned those elements. Not sure if that is a function of the category as you mentioned but it seems to be the case. Assigning the Use Annotation Scale parameter to those lines makes them appear when that parameter is checked in the project. Cahnging the visibility of the 2D elements so that is controlled by the Use Annotation Scale parameter makes the family behave as expected. 

Is this what you are looking for?

Good point, this should have been posted in the MEP forum. I did my testing with the Mechanical template.

It has something to do with the annotation lines that were used for the sweeps. I deleted all annotation lines and created new sweeps "not using the annotation lines" and all shows now in my project. I do think the project template was derived from the MEP.  I placed in in the Sample Arh project and the original family shows so long as I do not check the "use annotation scale" parameter box. It is not checked by default when placed. So I guess this is the answer. Remove the annotation lines that are in the original source family or live with the visibility issue in my company project templates.

Thank you to all who replied.😋

You've made a couple of incorrect assumptions but that doesn't matter if you got what you want. The unfortunate thing is that your ignoring some Revit fundamentals. Piping in coarse and medium detail level is usually single line representation. If your company doesn't follow that standard, reauthoring the family would be the solution. If you ever want single line representation, you won't have it available and will need to recreate it.
