I am trying to find points for the curve between two points These are my two points in x,z planes startPoint = new THREE.Vector3(1042.3745025363808, 0, -3017.6896180088434) endPoint = new THREE.Vector3(1042.3575319644679, 0, -3017.6726474369307) var vertex, i, center, p0, p1, angle, …

[image] Alex: I am trying to find points for the curve between two points There are infinitely many curves between two points. It is not clear to me which constraints you assume to get a unique solution. There are several very well described types of curves. Maybe you can make a sketch? One …

Hi @hofk , Sorry for the code format and thanks for quick reply. So here i am attaching the files that contain the points and also the shape i want to get. [polygon] points.txt (12.8 KB) Here is the code file that algo.txt (4.2 KB) Here issue is the bulge part is working for x,y plane but i a…

Now the thing becomes clearer. In points.txt you can see that only some corners are rounded. This is also visible in the image of the shape. From the formulas it can be seen that part of a circle is used to connect the lines. THREEx.Math.polar = function (point, distance, angle) { var result…

This is my fiddle link Edit fiddle - JSFiddle - Code Playground , after replacing it with z also its not giving me exact result. The fiddle is not so proper because i am using it first time , but it give you an Idea what i am trying. This is what i am getting [wrong_polygon] This is what i am exp…

Hi @prisoner849 , I always appreciate your help and i like you send some fiddle as solution. But my issue here is I have to use the points that i am getting from the cad files if you check in the fiddle there is an entity obj with some bulge parameter (means how the curve is) and i have to follow …

Hello @prisoner849 , I am attaching an file that have a working example. Please let me know if any one can provide me help to understand why the shape is not proper. polygon.html (6.4 KB)

Could you clarify, what and how does that bulge define? { "x": 8.816292322934935, "y": 5.51136731706687, "bulge": -0.414213562373095 }

Its a geometry of dxf file and this parser is parsing the geometry dxf-parser This is available in npm , here it is givimg me geometry in js obj form.

I just asked about a property and what it defines, and you offer me to read about a whole dxf-format and investigate its parser :slight_smile: That’s cute.

Seems, the solution is something like this: Line with rounded corners
