General information about spatial curves

Scroll

Curves can serve a variety of functions in a model. For example, they can be used as guides when constructing elements along a path or ruled surfaces, to create surfaces along a network of curves, and more.

In KOMPAS-3D, you can create the following types of spatial curves:

segment,

circular arc,

cylindrical spiral,

conical spiral,

broken line,

spline,

Conical section curve.

You can also Import 3D curves recorded in a file format of STEP AP203/STEP AP214/STEP AP242, JT, or IGES.

You can also truncate or extend Curves, as well as build the following objects:

spline replicating the form of the object,

curve by its two projections,

curve determined in the parametric view,

fillet corner formed by two curves,

joining two curves,

equidistant curve,

contour,

curves by surface:

Isoparametric curve,

group of isoparametric curves on surface,

outline line of face.

surface spline,

projection curve,

surface intersection curve,

folded and unfolded curves.

The curve present in the model can be rebuild or scale.

A model can contain so called curves without history. These objects appear after the arrays of some types of curves are exploded (see section Exploding arrays).
