Revit Lt, dashed line showing as continuous when hidden by floor

[lp6VYMR]

Hi everyone, 

I am having an issue which I just can't diagnose, I am using Revit LT and trying to do a foundation with a toe as shown in the attached. I have made this from two structural slabs that are at different levels so they overlap slightly  and the slanted part is just being done by hiding some lines and drawing a slanted line.

Now the issue that I have is that in plan i need to show in dashed the inner edge of the 750 wide toe, I can change the line type of that edge to dashed but it seems that when the upper slab is visible in plan that line is shown as continuous for some reason (even though its been changed to dashed), if I hide the upper slab then the edge shows correctly as dashed.

Changing the visibility style from wireframe to hidden line does show the line in dashed but also shows a continuous line right over it and when I try to print it it still comes out as continuous. 

Any thoughts on how I can fix this?

Have you used the View Setting tools in the Properties Palette?

Try adjusting the Discipline and Show Hidden Lines Settings

I would recommend looking at your slab overlapping.

I am not sure in Revit LT but does it allow a Slab Edge? (Slab/Floor > Drop Down Arrow)

If so create a profile (2D shape) there should already be one in the pre-installed Families and Edit it to your needs.

This may help the situation

Below is the OOTB Slab Edge and just offset -200 in the Horizontal

Hi, thanks for the reply,

Yes I have tried changing the "discipline" and the "show hidden lines" option but nothing happens.

I have added another screenshot showing what that line looks when using the hidden line graphic display options, in model space it actually looks like it is dashed but there is another continuous line right next to it which is why it print as continuous, that additional continuous line seems to be automatically generated by the slab at the higher level as, as soon as I hide the slab at the higher level, the line prints in dashed, presumably it creates that line where the two slabs intersect but cant figure how to get rid of it.

This is due to the slab overlapping, please see my response above hopefully this is achievable in LT and i didn't have to make not changes are regards visibility etc.

Many thanks for your reply,

Yes this does looks like this would solve my issue, only problem I have seems Revit LT comes preloaded with 3 slab edge types but cant seem to find an option to load others or tweak the existing one, any idea how I might be able to do that?

Thanks

You simply Duplicate and Edit the Profile to meet your needs

The easiest way to to this is in the Project Browser > Families > Profiles > Slab Edge Thickened > Select an existing Profile > Type Properties > Duplicate > give it a name and edit the dimensions to suit.

Then in Revit use the horizontal and Vertical offset in the slab Edge Family to position it exactly

Thank you very much for your help, that has sorted it, and now it looks like I want it to.

Any idea if I want to make the slab edge a completely custom shape, how can I go about doing that, as I can't seem to see an option that lets me open the slab edge family to edit the shape?

[jay_colcombe]

Again from the Project Browser > Families > Slab Edge Thickened > right click > Edit (do this on the Family not the Types)

This opens the Profile in the Family Editor > type VG (Visibility Graphics) and tun on the Refences etc.

That is great, many thanks again for all your help.
