Conversion of "SPLINE" to "POLYLINE"

[DixonBoats]

We are currently using CADViewer, and looking to buy the converter
if it can help us.

I tried converting a file with "SPLINE"s back to ACAD 12 "POLYLINE"s
which we need so we have a list of vertex points.
This conversion gave about 20 points on a curve that I tested.
Is it possible to increase the number of points to say 50 or more?
Also, can the point density be varied so that there are more
points where there is greater curvature (i.e. second derivative) ?

Regards,

Robert.

Hi Robert,

The exploded splines in dwgConvert are obtained via a call to a third party module for which we do not have the source. So unfortunately it is not just a simple matter of changing a couple of numbers to get the increased number of fit points.

On the other hand we do have our own source routine for exploding splines (used in our HPGL2CAD software). So in theory we could implement that to achieve what you want. I will log it as a suggested enhancement for a future update of the software, which is the best we can offer at the moment.

regards,
Paul G.

I think this is what you need:

This tool converts Splines into lines and arcs
