In what program to draw and how to implement 3d models on the site?

Question

css

Hello.
Push for the right solution. Googled, honestly, but I need to quickly implement, so I ask those who have already done this.

There are such photos, you need to quickly draw them in 3d models and put them on the site in the form of models so that people can go in, twist the stairs, see all its angles.
Actually, from here 2 questions:
1. What is better to draw in? Windows 10
2. How to implement for the site? At least a couple of code examples.

Answer 1

1) anything, you can specifically "extrude" (extrude) from a 2d form here. It is convenient to do such things in all sorts of autocads and so on.
2) three.js - there are examples and model loaders.

Answer 2

The simplest step by step:
1. Download Blender
2. Download the Blend4Web plugin (namely, the plugin!).
3. Install the plugin in Blender. Small video tutorial .
4. In Blender, a primitive cube is created at startup. Select it with the right mouse button, press S, then the desired coordinate key (XYZ) by which you want to scale the object.
5. Press shift+D to create a copy of the step and move (G key) to the desired coordinate.
6. For rotation - hotkey R
7. After building the stairs, export to html (file -> export -> Blend4Web (HTML))
8. At the output, get a player with a built-in model. Paste on the site through a simple iframe.
Good luck!
