Solid piping to Dashed piping filter

Anonymous — Fri, 27 Jan 2012 14:50:57 GMT

I have sanitary piping above the floor (ie parking garage) which must appear solid. When the pipe goes under the floor it needs to appear dashed.

I have been trying to set up a filter to do this which would cover all the underground piping systems I have, but have had no luck.

So, help me if you can, please?

Thanks

Using the view ranges correctly can help with this easily. Set your Bottom Cut Plane to be FFL or SSL - whichever you require. Then set the view depth to be below the Bottom Cut Plane so all your below slab drainage will show up. You also need to set you linestyle "Beyond" to be dashed as it is set as solid by deafult (I think).

That will then show what you are looking for. However be aware that as you start to look further below the bottom cut plane to see the drawing you may also see building elements appear.

The other options is to create a parameter for Vertical position, we did this as we required to see:

Below Floor
Low Level
High Level
Ceiling space

In one view, filters then to change linetype, can be laborious as the user needs to remember to fill in the parameter for each new pipe and pipe fitting. Would be nice to be able to filter by height but dioesn't appear to be readilt available, would like someone to prove me wrog on that one.

Hello,

i have the same problem. i cannot find the solution.

Both responses to the original question are solutiosn.

Just pick whichever one best suits what you are trying to achieve in your views.

Hi sforsberg215,

I am pretty sure that you had managed to get this fixed now considering you had posted your question more than 3yrs ago but I would like to respond to this in more detailed so other users in this forum, that may have the same question in mind, will find it useful.

Making the undergound pipe to appear as dashed lines does not need to be filtered. All we have to do is adjust the view range. See below screenshot for example:

Keep the bottom range to zero and make sure View Depth setting is below the depth of the underground pipe. In the example above, the underground pipe (dashed lines) was place at 600mm below ground, which within the range of your View Depth. If the underground pipe sits at -1300 then you will not be able to see it in the view because it is below the View Depth range.

hello all

I have the same problem, but it is a little more omplicated.

i have 3 kinbd of piping level let say o have floor ground at 0 level with 3000 height :

undergroung : -400

on groung : between 00 aand 300

underceiling : 2900.

with duct we have the level propertie and i can add filter.. with piping i could not find this.

The view range settings are how you achieve this for sure. However my hvac and pipe systems all have system graphic overrides to control the color of the systems so my engineers can work easier. These overrides actually override the view range "beyond" linetype. I introduced a new filter to make the colors black for use in my arc hitectural drawings and in their finished sheets but leaving the linetype option as by category in the filter does not reinstate the dashed line I am looking for in my underground HVAC drawings.

IS there a fix for this?

This works great but how do you maintain the line thickness?

Typically the line types that are not bold are existing or out of scope but we need to show it as new.

The project I am working on is a new building and all floors have below slab sanitary plumbing rather than showing the plumbing in the ceiling.

When I adjust the view range the piping line type is overridden to a thinner line. The dashed line pattern is correct but I need it BOLD.

Thanks!

I found a solution...simply change the line weight to what Revit refers to as "beyond" in line styles and make it the same weight as your system weight.

This only works for when you're showing stuff below your view's "bottom" depth but above your view depth.

It may not be the 100% fool proof solution but the drawings seems to make a lot more sense now. Hoping this can be a new standard but we'll see.

Hello,

In our office we usually use view depth and bottom in the same position.

Ideally yes, we would set our view depth at zero and bottom at zero for ventilation, heating/cooling and fire protection, etc. but for plumbing it is different. Unless you strictly show stuff in the ceiling that serves the fixtures above this will work but for when you have stuff above and below we would need to make a difference.

Hello,

We also use filters to not show the undesired objects.

Usually our bottom is -50cm.

Hi,

I have a problem similar to this but I CAN get the underground piping to display dashed. However my issue is I need to differentiate between system types. Some system types i want to show dashed underground while at the same time some I need to show solid. for example we show our drain lines underground solid and the vents dashed. is this possible? Help is really appreciated

Can be done with a Filter. Out of the box functionality will not allow it. Dynamo may be able to help as well.

You could use filters or you could just apply graphic settings within the system type properties to cover the solid line for drainage below slabs and use the same method or previous view range methods for the vent. There are many ways to solve problems in Revit, up to you which you find the easiest and simplest way to manage your model whilst also considering making it as easy as possible for others to pick up and understand what you did.
IMHO - whilst Dynamo is the next big thing that we live to play with and can benefit from, it can sometimes be a little overkill for dealing with some of the simpler modelling strategy, settings based issues, etc.

Hi @CADTripper

I tried this and the Pipes in my model is not getting dashed or hidden lines. Could you help me what I'm missing. I have attached few images and snaps and model for your reference

Please help me to understand what causes this issue. and how do I get dashed lines. Thankyou
