Smooth 3D polylines

[Hrcko]

Hi!

 

I am making the drawing of the ship model. The hull has been modeled in Delftship and exported as DXF file. The sections look like this:

 

 

Notice how section lines are smooth.

When the DXF file is opened in AutoCAD the sections look like this:

 

 

Green arrow - I want that line quality.

It is possible to see that the section lines are not smooth.

 

How can I make the lines better (smooth)? I tried polyline edit but could not obtain what I want.

 

Thank you for the comments and the help.

Perhaps you could post a drawing file with half a dozen wonky lines in it?

 

That way, someone could look at it properly, and try and work out what is happening.

Hi, Eldon!

 

Here is a drawing with reduced number of sections. I believe that the situation now will be more clear.

My guess is that the conversion programme to DXF is not accurate enough for your needs.

 

AutoCAD can only use what it is given, and there are definite lurches in the linework. Pedit cannot cope.

Don't know anything about your wishes of density.

See the attachement (Polyline reduced and Spline).

I think that you should be working to more decimal places before you create the DXF.

 

The lines have wobbles which are 0.0001 offset. It may be that if you were working to eight decimal places instead of four, the wobbles would not be so noticeable.

Thank you scj and eldon. I will try to scale ship hull by 10 and increase the number of decimal places.
