Complex Roof

Jerryjb — Tue, 25 Feb 2025 23:12:23 GMT

Prior to adding this to the Wish List, I thought I would ask if anyone knows a way to change the elevation of the lines of a roof independently from the others. As an example, I have a hip roof with all eaves at the same elevation but I want the entry to be elevated above the rest. Currently I break the roof into individual planes and then continue manually editing. I am looking to see if there is a way to just elevate the portion over the entry pop-out without breaking the complex roof.

I find it easier to deal with single roof planes when dealing with roofs at different heights.

But I am 'old school', from before the time of multi-plane roofs.

You could add a second multi-plane roof for the porch and then connect it to the main roof.

Or you can play around with the 'multi-plane geometry' and add a second pitching level

I think you then make the lower level around the porch all gable ends (so you don't see them.

Not really sure as I just convert to single roof planes.

The issue with using a second multi-plane is that the right pitch continues up giving you no clean spot to butt into the main multi-plane resulting in a non-existant edge on your floor plan.

You could draw a polygon around the area that you want to pitch the separate entry roof from. Then set the parameters of the entry roof and then just magic wand around that polygon to create your entry roof. Wholla !

I typically use single plane as well. I was hoping to use the complex roof as a little time saver to rough the roof in. The issue with just adding new planes and tying them into the complex roof is that you loose the ability to trim the roof planes. This becomes very manual and tedious. At this point I just break the roof which then makes all future perimeter or pitch changes very tedious as well.
I think one of two options may resolve this. Somehow allow which plane of the complex roof to trim too or allow setting the elevations individually for each of the perimeter lines of the complex roof.

This method works. Connecting them or performing an SEO gives the correct roof lines on the floor plan as well.

Model the complete roof as you have done.

Then select and add a second pitching height.

Now select the lower pitching lines and change them to 'gable'.

Now you will have a higher roof.

I just can't remember how to tuck the lower eave under the upper roof if you want to do that.

I don't think you can with a single multi-plane roof.

It is not the trimming body to contour or pivot line - that has no effect.

Two separate multi-plane roofs you can do that, but only to contour of pivot line of upper roof.

But single roof planes you have even more control as it doesn't have to be trimmed to the pivot line.

And I think the floor plan display of overlaps is better too.

Thanks Barry

this is super helpful. This will allow me to keep the flexibility of the multi lane roof for as long as I can through the design process and then break it when I’m ready to clean up the last details.
