you can refer to this LINK lots of tutorials for complex roof. thanks

This is correct ? How it's (going to be) made? Just checking.

rooflines

[ayushi.s]

Yes you are correct, that is like that in roof plan.

[martijn_pater]

I would roughly create it something like below probably, combining four roofs together. Are you familiar with methods like using slope arrows and/or roof join tool?

[ayushi.s]

Yes i know slope arrows, i tried that way but no success, can you please help little more.

[martijn_pater]

...actually easier to define these three sketchlines with negative slope. No need to use slope arrows then, but below as an example how you could use those.

Thanks, I really appreciate your help, can you please share a screencast or procedure to follow how to do it from scratch.

Have you tried using Roof Cut Off? Maybe that would be easiest for you.

...or maybe even the SHAFT tool.

Be interesting to see what this question-marked area is all about...

[ayushi.s]

Thanks for helping me out, question mark area is flat roof.

[barthbradley]

Ah sh*t! Wish I knew that. It was my very first roof and then I starting messing around with different configurations that took way to long. Looked like drainage crickets with integrated down spouts.    

[ayushi.s]

Roof at inside portion is of negative slope. It is going downward at inner side. and there is flat slab also in middle portion.

[barthbradley]

I figured as much. It's pretty obvious. We've built many like this. Mostly commercial. Yours look residential. What country?     

[ayushi.s]

Yes this is residential.

[martijn_pater]

ow, thought it was an inner courtyard...^^ You could use modify subelements on a flat roof...

@ayushi.s 

I suspect that the transition between the sloped roofs and the flat roof will require a minimum vertical height to transition between the two different roofing membranes. 

If that is the case, can you tell us what the elevation of the flat roof relative to the ground floor level?

Do you have a reflected ceiling plan showing the required interior ceiling heights? 

I suspect that the roof transition between the sloped and flat roofs will require vertical walls which explains the lack of counter slopes on the left and top (see annotated plan)

Nice section scribble, hehe. But yes, perhaps sharing some sections would help...

@martijn_pater 

Nice section scribble, hehe.

I was trying to show the accumulation of snow on the flat roof 😉

What happens you buy a $$$$$ computer and software and you find yourself dragging a finger across the screen to draw a line! :-0
