BREP.io A browser based parametric modeler.

So I got a github issue today requesting a helix feature. 
https://github.com/mmiscool/BREP/issues/5

Added the first cut at at helix functionality has been added. Please go ahead and test.

Hole feature:

Options for Simple, Countersink and Counterbore:

Hole PMI callout:

Been working on BREP.io and started adding some some sheet metal functionality.

The out of the box threejs transform controls gizmo is not great for CAD applications.

My new replacement dose away with needing to toggle between move and rotate mode. Drag the arrow heads to move and drag the balls to rotate. So much more natural.

Below are what the normal threejs transform controls look like. 

Pipe feature examples. 

In the past implementations the fillet feature took a long time to run and would slow down significantly as you added more fillets to the model. 

Now filleting is working extremely fast!

It still is not quite perfect yet but I am very happy with the results for now. 

Added an "Update components" button that detects if you have changed any of the part files that are used in the assembly and lets you update them all with a single click.

Added an option to automatically solve everything as soon as you change a constraints value or selections. 

Added some automatic error detection for constraints that conflict and made the constraint labels color coded so you can see what is failing, what is solved and what needs to be solved. 

Example of a failing constraint. You can't use a touch and have a distance constraint between the same set of faces. 

Added the ability to use math expressions for assembly constraint input fields.

Also made it so that while the solver is animating it displays unsatisfied constraints in yellow until the constraint is satisfied and turns green. 

Did some more assembly constraint solver work today.
Made it so that you could actually watch the solve cycle and did a bunch of usability improvements. 
Got edge to edge constraints working good.

In the video I demonstrate the touch constraint and angle constraint solver. 

Started working on a little 3D constraint solver for assemblies in BREP.io
