Mansard Roof

Quote from Ozorvals

No problem

Avanar gave you three very useful commands and you also clearly know how to use the "size" command, so I won't go over again.

That leaves the "rotation" command; it's used like the "size" command with the same parameters: "rotation 90 0 0" allows, for example, a 90° rotation on the X-axis, and "rotation 90 90 0" a 90° rotation on both X and Y axes.

In a more pragmatic way, you position your block in modular snapping on a chosen snap point without placing it, you enter the command, the block flips, and then you can place it. Nothing more. Of course, the choosen snap point is the center of rotation.

However, be careful with this command: the rotation is absolute, meaning its parameters are only true for a block to which you haven't previously applied another rotation. Think to push BACKSPACE key first if you have any doubt.

Thanks for the clarification. So helpful

OK, I've got the sizing and slope. I'm using your example figures while I practice, I get the piece sized and sloped, I then use surface edit to shrink the top, when I do this the pattern warps. How do you keep it straight?

They are two methods to do this, one simple, one complex. You try to use the complex one by using a square block and shink the top. Its possible to do that well, but that need more calculation. I can describe this in details if you want.

However, I often use the simple one: You place square blocks in the center (greens on the screen below) and slope blocks at the edges (blues). Slope blocks dimensions are similar to the squarre ones, but the order change, try and error is the fastest way to find the right one. With a snap point on a green block, few 90° rotations are also requiered to obtain the right orientation; do this with arrowkeys.

You can examine my example figure in details to understand this more easily: you have the dimensions and rotations info of each block (red circles) if you point it with a block in your hands.

Thanks so much for getting back to me. I'll use the simple one for sure. I notice that on top of your roof blueprint you have two mansard roof pieces and 2 triangle pieces. How does that work? So, do you have to rebuild the wall 3 more times or is there a way to copy it complete.

I'm not entirely sure I understand the question correctly.

If the problem is creating a mansard roof, it's essentially two roofs stacked one on top of the other. You simply apply the method twice, changing the spreadsheet settings and deleting the unnecessary blocks at the end. Once you've finished the lower part of the roof (green and blue in the previous post), the edges of the blocks at the top should still be aligned with the grid: You build 4 new walls using the grid and run the method again.

If the problem is the roof section with only two triangles, I place a temporary "green" block aligned with the roof's midline, place the first triangle, delete the temporary block, and then place the second triangle.

Once I've built one wall with squares and slopes, how do I get the next wall to fit if I have to build it again from scratch
