Pipe Fall Gradient 1:96

[pinaki.rajak]

Hello Friends,

A Fabrication Pipe drawn at fall gradient 1:96 but the variation of the elevation showing same at both the end. It should be differ right?? 

can you please check and reply the probable solution?

Thanks

If you hover over the pipe it actually says 1:96 in the tooltip?

If yes, then I promise you the elevation is different at both ends. What could be going on is a lack of reporting from the opposite end in the tooltip. If you see C1 then you know it is reporting Connector 1 elevation. If you go to the other side and it doesn't change to C2, then it is still reporting the Connector 1 elevation.

Please verify the elevations with the AutoCAD ID command and that the tooltip is indeed saying 1:96 on that pipe. If it is and the ID command also reports the same elevations, then please upload a DWG for me to look at; I'm confused.

Dear Sir,

First of all many thanks to make my question as part of your review. Secondly, Yes, it is actually saying 1:96 in the tool-tip. I have also verified the elevations with the AutoCAD ID command as per your instructions and found accurate result so the pipe is taking absolutely correct slope as provided (1:96).

The problem is pipe elevation in the tool-tip is showing the same for both the ends.  

you said in your earlier reply that, "If you go to the other side and it doesn't change to C2, then it is still reporting the Connector 1 elevation"

and i think this is the actual problem.

Sir, it would be a great help if you kindly provide some tips to get it corrected.

Please find attached to know the exact problem

I have never figured out how to just start laying pipe in and have it sloped. I always have to use design line and set the design line at 1/8" slope (1:96). When using the design line though make sure you go to >Line>Drainage Tool and the software is usually pretty good at finding the lowest point but I always click Define Source just to be safe. Don't mess with the Set Pitch Pont button, just select the 1:96 from the Fall dropdown menu (1/8" per foot). click OK and you should be able to look at a side view and see your Design Line sloping. If it is then click the Fill In 3D button and you are rocking except the software sucks at trying to put in wyes and just leaves them blank so most of the time you still have to go and put those in manually, but when you do put them in they will be sloping with your pipe.

O/T Does anyone know why they have slope in engineer scale in ratio (1:96) instead of architect scale (1/8"). Also, If anyone knows a way that you can just start dropping pipe in at a slope (similar to Fabrication Parts in Revit) I'd love to know too.

I think it must be for people outside the US/UK that use metric.  It is a ratio rather than a foot inches mix.  Now as far as people outsourcing their inch/foot jobs to countries that use metric, I can see where this would be easier to use.

The engineer scale is used because the architectural scale uses imperial units (1/8 inch per foot) and inches create issues with metric as well as make dealing internal calculations a bit more cumbersome.

"Start dropping pipe in at a slope" can be done by starting with a slope to the initial pipe placed.  Fittings will take on the slope of the pipe as they are added - as long as you continue in the same direction.  Slope for branches or changes in direction will need to be "initialized" to set the slope for the branch direction.

I like using the UHP Route Lines program in conjunction with the Design Line Trace option.  Route lines are used to layout the pipe run centerline  - complete with slope -  and are exploded before using the Design Line Trace option to generate a matching design line - one which allows multiple slopes on the same Design Line which will fill completely providing the user has a valid layout. 

Here is a link to a video showing how this is done: https://youtu.be/LTIwLfvcznk

I also "wrap" CADmep content using a different software package and then populate route lines (sloped) which allows me to add individual fittings without using the Attacher and place them fitting-to-fitting or anywhere along an existing pipe.

I have noticed the same problem in 2017 regarding the elevations of sloped pipe only reporting from one end.  Could you please let me know if you get a solution.  I figure it must be a setting but I cannot figure out which one it is.

Thanks

Upgrade your Fabrication cadmep with latest release.

You can use the FILLPOINT command or Multi Point Fill button and route sloping pipe much like you do in revit.

Pick the starting point for the run and then choose the "Elevation" option and enable slope or "Work to Fall" and set the ratio desired.

From there it is point to point with all piping and fittings sloped.
