# Viewport association fixture
|
|
|
|
`viewport_associations.dxf` contains line, circle, arc, polyline, spline,
|
|
block-instance, and intersection references through a 1:2 viewport.
|
|
`src/app/viewport_dimension_tests.rs` tests refresh and intersection source edits.
|
|
|
|
Each dimension stores `DIMLFAC=-2` and `ACAD_DIMASSOC_CALC_DIMLFAC=-2` so its paper
|
|
definition points measure in model units. The spline tangent from `(0, 300)`
|
|
touches `(90, 283.125)` at parameter `0.75`; tests verify its tangency and preserve
|
|
the dimension if an edited reference cannot resolve.
