Sheet - OpenGeometry

class Sheet extends Body

import {
  OpenGeometry,
  Sheet,
  Wire,
  OG_OPERATION_SWEEP,
  OG_PRIMITIVE_CIRCLE,
  OG_PRIMITIVE_POLYLINE,
} from 'opengeometry';

await OpenGeometry.create(
  { wasmURL: '/opengeometry_bg.wasm' },
  { workerURL: '/tessellation-worker.js' },
);

const profile = new Wire(OG_PRIMITIVE_CIRCLE, { radius: 0.1 });
const path = new Wire(OG_PRIMITIVE_POLYLINE, {
  points: [
    [0, 0, 0],
    [0, 2, 0],
  ],
});
const sleeve = new Sheet(OG_OPERATION_SWEEP, { profile, path, caps: false });
console.log(sleeve.validity());

Constructor

new Sheet(kind: string, params: Record<string, unknown>, options?: BodyOptions) The only kind is OG_OPERATION_SWEEP with { profile, path, caps: false }. With caps the sweep makes a solid, so new Sheet throws BodyTypeMismatch.

What a sheet can do

It shows its surface, from the front only, and its outline.
It has the Body methods. duplicate(options?) and instance(options?) return a Sheet.
It has no operate. It is not thickened into a solid.
exportStep and exportIfcBody refuse it. classifyPoint throws InvalidOperand.
