}Does anyone know how to write out a cubic spline to a DXF file so that
}3DSMAX will import the data as a spline? I am currently writing out a
}polyline with the following attributes:
}and I write out each spline control point as:
}but when I import this data in 3DSMAX, I don't see the outline. The shape
}is there and the vertices are there but ...no line.
My guess is that it is this:
You havn't specified a layer (type 8 thing) for your verticies. This
is apparently necessary. I think the DXF specification sayas that every
entity has to have it, and a vertex is an entity (the DXF file I just
looked at specified it for every vertex, as well as for the polyline entity
itself - yeah, I know: the DXF format is one of the most rediculously
inefficient formats ever created, it's trivial to fit all the information
in half the space while simultaneously making it much more easily human
readable). You should make it match the one for the polyline.
