Mansard Roof

If anyone knows how to build one of these roofs I would sure appreciate the help.

Quote from Avanar

Take a block with suitable texture

Use the surface-edit (on my keyboard it is the Alt Gr key) and change the shape so the lower end remains in width and the upper end is more narrow.

close surface editing and use the regular resizing-possibilities to have a thin board, rather than a block

now you can fiddle around the "block" to allign with each other to the roof you like

i think this is the best i can explain it here. the key is the surface edit mode through which you can individually change the shape of one side (the upper) of a block.

Thanks Avanar, I'll practice with it. How does that relate to corners like in this picture?

Avanar already gave you the easiest method. Create a complex roof is never easy but it's also possible to calculate the shapes (with a spreadsheet) to do a fine work with console commands. If you are interested (and not afraid by numbers) I can share my spreadsheet and try to give you some explanation.

I use console commands (specifically the size command) all the time. I don't have a program to view spreadsheets though.

It is not easy to find the right angle. Small gaps can happen, if you are not working 100% accurate, but can be covered with beams or similar that cover the corner anyways. Or you follow the accurate path of Ozorvals with a spreadsheet.

Still it boils down to fiddling around with it. Roofs are a science on its own - there is no easy way, if you want it to be good

Thanks for the example! Yes, roofs are tricky. I'm going to practice this but it will take a while. I've never used surface edit.

You just need LibreOffice (witch is free) or any commercial equivavent to read it.

I share the file, if you want to try. It lets you do trigonometric calculations effortlessly; you just have to fill in the green boxes. Don't change anything else. In your case, you can also ignore everything related to conical roofs or roman tiles.

So you have two values to find, which are specific to your situation. The module is (to simplify) the width (in blocks) of a slope of your roof as seen from above, so generally half the width of your room, including the walls. The height is (to simplify) the height of your roof between the ridge and the top of the wall.

Once completed, the construction method is similar to what Avanar showed you. For example, you can find the exact angle in the first table (named "Angles"), and then you just need to use the /rotation command to correctly position your block IG. However, I recommend experimenting IG first to find a value close to your angle so you can more easily find the correct value in the table, which covers a wide variety of cases.

Furthermore, if you want to see an example, dismantle the barn I posted yesterday, its roof - quite simple - is made with the default values of this file.

Thanks for the help. I downloaded Apache Open office and I'll get that barn. It's time to take a deep dive into roofs.

It's going to be a learning process and might not be easy. In fact it will be frustrating. But once you managed you'll feel a deep satisfaction

You can open a spreadsheet with any excel like software. Open office or Libre office. Both free

Thank you for the tips. This should he "interesting".
