Solved: Re: SPOT SLOPE / NO SLOPE

flognaw00 · ‎08-07-2023

I'M PUTTING A SPOT SLOPE IN A PIPE. HOWEVER, THERE ARE PIPES THAT DO NOT HAVE A SLOPE. I also confirmed that there is no problem with PIPE, and other pipes have a SLOPE without any problem

What is the question?

flognaw00 · ‎08-07-2023

I HAVE A SLOPE ON THE PIPE, I DON'T KNOW WHY I CAN'T SHOW IT

iainsavage · ‎08-08-2023

If you select the pipe and look in its properties you will see the slope value and despite what you say I suspect that the pipe doesn't have a slope.

Example:

what do you mean "cant show it"?

is it not visually showing a slope in section/elevation?
is the slope you added not showing in the properties?
are you trying to tag it and it not showing the right %?

When looking at the characteristics of the pipe, the slope is displayed normally. But when I try to tag it, it says there is no slope.

Look at my screenshot posted earlier.

Please post your version with the pipe selected and the slope value displayed in the properties panel.

hmunsell · ‎08-10-2023

I looked in the out-of-the-box tags and i didn't see a Pipe Slope Tag in the Annotation library. There is one for "Fabrication Pipe", but not for regular pipe.

If the slop is displaying in the properties correctly when you select the pipe... what Tag are you using?

if you place a Spot Slope on the pipe does it show the slope?

@hmunsell when you use the spot slope tool on a flat pipe it displays as [No Slope]

This will also happen if the slope value is very small (not sure what the cutoff value is but by trial and error it seems to be about 0.175% (about 0.1 degree)?

@flognaw00 if you do as I asked and select the pipe to display its properties and post them here then maybe we can help you better. As well as displaying the value in the properties panel it should also display as a temporary dimension in the view:

If its not showing this value then the pipe has no slope or a very minimal slope.

hmunsell · ‎08-10-2023

@iainsavage you are correct. if there is no slope of if the slope is 0.1 or smaller, it would display as No Slope. like you, i am interested in seeing the properties of the pipe in @flognaw00 's model 😁.

I was putting tags using SPOT SLOPE.

flognaw00 · ‎08-10-2023

Thanks so much I found the cause. But I also wonder if it is possible to change the 0.175 value.

flognaw00 · ‎08-10-2023

thank you so much

So what you are saying is that your slope is less than 0.175% (1.75mm per metre, 5/256" per foot, 0.1 degree)?

What would be the practical purpose of that? I don't think anyone would, or accurately could?, install a pipe at such a small slope.

hmunsell · ‎08-11-2023

for everyone else that might view this thread, What was the cause?

What I'm designing is that the pipe slope should be rounded off and come out at least 0.2%. However, it seems that less than 0.175 came out because revit showed the rounding as it is without expressing it.

flognaw00 · ‎08-13-2023

What I am currently designing should be 0.2% when calculated by rounding the SLOPE. However, since the BOP calculated by rounding up the SLOPE was used, a SLOPE error occurred.

You CAN set a slope of less than 0.175% (although I'm still not sure what practical purpose that serves)

but Revit won't display the value in the spot slope "tag".

If you really must have such shallow slopes and be able to tag them then I think you would need to use Dynamo.

You would create your own shared parameter and load into your project and associate it with the pipe category.

You would load the same shared parameter into a tag family and use it in the label.

You would then use Dynamo to extract the values of Slope for all pipes and transfer those values into your own shared parameter, then you can tag it.

There have been other posts about extracting the slope values and transferring them to a shared parameter so I'm pretty sure someone's already uploaded a Dynamo script already written for that.
