Dimension

Creating a Linear Dimension (DimensionLinear)

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  const dimensionRef = operation.createDimensionLinear(
    model,
    [0, 0, 0],    // start point
    [100, 0, 0],  // end point
    [0, 0, 20],              // offset vector
  );
  const dimension = await operation.entityForRef(dimensionRef);
  console.log('Linear dimension:', dimension);
  console.log('Text:', dimension.text);
}, 'Create a linear dimension');

Attaching to Entities and Instance Paths (DimensionLinear)

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  // Create a group with geometry
  const groupRef = operation.createGroup(model);
  const edgeRefs = operation.createEdge(groupRef, [
    [50, 0, 0],
    [100, 0, 0],
  ]);
  const edge = await operation.entityForRef(edgeRefs[0]);

  // Create dimension: start attached to entity, end attached to instance path
  const dimensionRef = operation.createDimensionLinear(
    model,
    { entity: edge, point: [75, 0, 0] },  // attach to edge
    { instancePath: [groupRef, edge.start] },  // attach to vertex via instance path
    [0, 0, 20],
  );
  const dimension = await operation.entityForRef(dimensionRef);
  console.log('Dimension:', dimension);
  console.log('Start entity:', dimension.startEntity);
  console.log('End attached to:', dimension.endAttachedTo);
}, 'Create dimension with entity and instance path');

Creating a Radial Dimension (DimensionRadial)

let model = await SketchUpApi.getActiveModel();
await model.performOperation(async operation => {
  // First create a circle
  const result = operation.createCircle(
    model,
    [0, 0, 0],
    [0, 0, 1],
    24,
  );
  const circle = await operation.entityForRef(result.curve);

  // Create a radial dimension for the circle
  const dimensionRef = operation.createDimensionRadial(
    model,
    circle,          // arc curve to measure
    [-10, 20, 0],    // leader break point
  );
  const dimension = await operation.entityForRef(dimensionRef);
  console.log('Radial dimension:', dimension);
  console.log('Text:', dimension.text);
}, 'Create a radial dimension');
