Roof Tool Negative Pitch - for Drainage Plan Floors

Hello!

 

If it would be possible to use the roof tool with a negative pitch, modelling floor elements for drainage plans would be so easy.

Thank you:)

Just split to single plane roofs and flip the pivot line.

It is possible. Just mirror each roof segment, so the pitch mark for each segment will be in the middle. You'd need to use the single plane geometry method for that.

For solid structures with a leveled bottom side the mesh tool is a better choice.

I know it is possible, its just that with a minor change to the tool like this, a lot of time would be saved. Also if there ever is a change to the drainage-plan and some drains have to be relocated -- you would have to change every roof element and adjust them to the new plan. When were working on large projects, this can take quite a while to do.

May be you can develop such element in Param-O easily, so can get repeated or modified easily as when needed.

 

Or

 

Construct required roof in shape of expected drainage element with its apex towards +ve Z axis. Convert the roof into Morph. Later rotate the morph to get the drainage element upside down.

Using the mesh tool could also be an option for modelling drainage, in my opinion it depends on the situation which one is easier to use.

Just use single-plane roofs, which you will need to in any case as soon the model gets past the very first rough sketch. Screen Shot 2021-09-24 at 1.01.29 PM.png

Can we just stick to the wish that Jensth made? He wants a roof with negative pitch, I want that too.

Still looking?
