I want to measure things like distance between two objects and its angle etc and also i want to show things in pop up window like object name etc when i hover over it
Hi!
About measurement, take a look at this topic: [SOLVED]Mesure distance between two points on a object by clicking
that i can use for distance i aware even you thought me a lot what about angle measurement and popup how we show popup in a seen
Feel free to read the documentation: https://threejs.org/docs/#api/en/math/Vector3.angleTo
It’s not so clear what you mean with “popup”. Use raycaster, and if it intersect a mesh, then show an html-element with information.
is it possible to render the pop up https://react.semantic-ui.com/modules/popup/ like this with the vertices that we have if it satisfied the condition near to the intersected vertices
in three js there is no unit
You decide the units of your own models. When importing models from others, hopefully they will have included a specification of what a “world unit” means in their model, which you can convert into a suitable scaling factor that you apply to the model to get it into your units.

You can try to use something like that: https://threejs.org/examples/?q=css2#css2d_label
you are really helpful we are done with the distance and label soon contact to you for angle etc thanks
