Invert inclination angle of pipes-

[l_masotti]

Hello guys,I found often very uneasy to redraw pipes with an inclination angle, because to fulfil  objective of designing pipes in my job,its often necessary to mirror  or invert the direction of their inclination angle. In Revit, I found the only way, manually resetting the quote of its vertices. Is there any faster way than redoing the desing lines alternately?

"often necessary to mirror  or invert the direction of their inclination angle" - I'm interested to know why you need to do this "often", what is generating this workflow?

There are various methods for changing pipe slope, or creating the correct slope in the first place, but it will depend on the extent to which your pipes are connected to (and therefore constrained by) other pipes or fixtures and also on the ability of pipe fittings to flex to the required angles.

Could you provide more information with examples of what you are trying to achieve?

Basically, Iam doing a Cad to Bim work, which subtancially asks me to draw pipe lines  without knowing which is the highest point of the trace. For example when I join more segments of the condensate drain water system, is difficult, without being a project designer of the entire plant layout from which equipment you need to start to draw on a way down /up. Each new modification of  equipments position could affect the drainage network quotes and   first constrain need to chaing the breaks of the dorsals.  To fasten this job, when I have a group of pipes from the right mep system and inclination angle, It should be interesting just mirror more than re draw I think

Okay so that's a strange design process, placing equipment and pipes before you have a design and know where things are and what direction they are flowing/falling/rising.

Ideally you would place the equipment/terminals in the correct place and then work towards or away from them, the elevations of the connectors on the equipment/terminals then determine the start/end elevations of your pipes.

You can try using the slope adjustment tool but if the pipes are anchored by connections to equipment you probably won't be able to change the slope angle much and almost certainly won't be able to change the slope direction, so you would need to break those connections first.

Tab-select to select a whole pipe run and then select the Slope tool:

If you want to reverse the slope direction you will first need to use the Slope tool to remove the existing slope:

Then tab-select again and select the Slope tool again:

Now in the slope editor you should see the Slope Control Point enabled. toggle it to the end (or if you have branches the location) which you want to be the lower end of the slope:

...and then apply the slope:

Slope is now reversed for the whole run.

Its not fool-proof though, it won't work in every instance depending on how your pipe run is laid out - you will probably end up having to disconnect sections to apply slope and then reconnect them.

Hope this might be of some limited help.
