How to create roof with different bearing height without API

[veeresh.huvinahalli]

 

I'm trying to create the roof as shown above but I don't want to use any existing API for creating roof is there any way we can use only points/line data to get desired roof as shown above with different bearing height.

So this is a 2D drawing?

 

How have you come to the geometry we see on this sketch? You have no other data - elevations drawn etc??

 

BTW, why is there - what seems so be - a roof edge shown if this layout is Top Plan?

 

Marked here....

 

 

The time consuming way of prepping a (resultant) roof plan off plan/layout/elevational heights is to overlay your roof pitch lines (from different bearing heights as you state) and create the plan geometry - assume you do have the roof pitch?. That is pretty much basic 'technical drawing'.

 

Providing a better insight into your reluctance to use a capable 3D software package for this might help someone guide you better......

 

    

 

Roof shown as I don't have wall data.

 

Not sure you're going at this from the right direction. Seems much too cart before horse.

There are several ways to go about this, but I noticed you indicated Line data as one.  If you created the outline of your shape with  3D lines.  Then the following would be a potential solution.

 

- After you have your shape outline in 3D lines.

- Convert them to NURBS

- Select the lines that form continuous planar surface (then the step below)

- Go to 3D power pack and choose "Create Surface from curves (this will make solid planar surface)

- when you have all your surfaces, you can use "Add solids" if you wish

Basically, I will have wall in lines form as shown below in diagram below with the roof pitch and bearing height as shown to each side of line 

[Gadzooks]

So your first sketch was out since the rear pitch was not drawn with 45º lines (hips to ridge) - leading me to believe that pitch was steeper. 

 

You're also forgetting - correct me if wrong - the roof needs to overlap the wall extents

 

This was sooooooooo easy to create - even with having to input your 'freedom units' changed to mm. You're going to have to grasp the nettle and draw in 3D

Sorry - should have noted I used your new drawn layout as being correct since there were no dims given

Thanks for the update on it, Is there any calculation formula/logic can we use to draw those lines on button click and create roof lines as drawn in new update image without any API reference.

You’re sounding like a student - yes?

[veeresh.huvinahalli]

Yes😅

I’ll pm you rather than provide a basic geometry lesson to others. 

[veeresh.huvinahalli]

Yes sure, Thank you for the  support.
