<IMDJS_MeshTools>

this addon is for the mesh modification and manipulation

when you have selected one/two/three/four edges,press "arch"or"curve" button ,

it will generate virtual auto curves with controller.

you can adjust the controller to fine tune the shape of curve:

all the curves are restricted to a plane (which is defined by the curve angle)

when your mouse is hovering to one controller it will turn yellow,

now you can press Left mouse button and drag to adjust the positon of curve point,

or you can press W button to adjust the weight of this curve point

(can make a right angles, for example).

In addition to this main feature, there are other small features.

Bridge welding: the corresponding two edges can be selected and their vertices can be welded in two phases.

Vertex alignment: you can choose vertices to align them in different ways (straighten/all vertices to select points)

Rectangular: to make a face at right angles by selecting it.

Axis to selected: the axis of an object can be moved/rotated to the selected element by selecting the element.

Convert mesh to curve: convert selected edges to curves.

Space curve vertex: average the selected curve vertex distance.

Select similar uv: select one or more vertices and press the button to select other vertices that have the similar uv coordinate.

=====update=========================================================

2020-01-10:fix the problem of when ui_scale is not set to 1.0, the curve of handles not fit the mesh shape.

2020-01-26 improve the algorithm of edge weld.
