Dealing with splines imported from AutoCAD

[inbal]

Hey Guys,

Do any of you have a solution for splines imported from AutoCAD?

The problems are:

1. Splines are exploded in the import process and can not be edited as arcs in SketchUP.
2. Splines are imported as individual segments and the result is a shape divided into 12 segments and it looks awful.

I know there is a plugin for arc segments but I am looking one for splines.... Any Ideas?

Thanks,
Inbal

Fredo6 has a plugin BezierSpline that can produce several types of splines and curves. It also has right click features to edit and adjust convert these curves. Click on the Plugins Index red button at the top of the page you are on. Scroll to Fredo6, click on the BezierSpline link.

Also, just a jab, Splines in Autocad are troublesome enough in Autocad let alone exporting them.

Hi mitcorb,
Thanks for the answer but I am looking for a solution to imported splines: and not to trace them one by one with another spline..

I took Mitcorb's answer at face value (edit and adjust). I don't tyhink he was suggesting a trace over. Am I wrong?

Yes, Fredo's BZ tools has the option under context menu to convert a set of edges to various curves. Whether you will get the result you need, you'd have to experiment. After the ACAD splines are imported, it is just a collection of edges as far as SU is concerned, so the tool has to interpret what the edges mean for the chosen curve shape. May need user help.

I guess I misunderstood. However, perhaps "Recurve" or "Weld". Then "Convert to" in BezierSpline right click?

Hey Guys,

I tried it: I took a line and recurve it or weld it and then with right click converted it into "Polyline segmentor" from the Bz toolbar of Fredo's plugin, and then changed the number of segment to 200 for example, but it didn't made it smoother, just divide it.

I did manage to make it smoother with the Subdivide and smooth plugin, but that action helped only one contour of the face and it is not a solution...

so- isn't there any way to import a spline from AutoCAD and not to regret it?

SketchUp doesn't do unsegmented splines/true curves. The workflow mentioned above is the best solution.
