Best way to import dxf,stp from solidworks ?

Harshal Shah Aug 27, 2012 11:19 AM

I have a closed spline with 18k co-ordinates completing it. My machine shops have been complaining that when i send them a dxf , step or even the original solidowrks file & when they would import it into their CNC mills the smooth curves end up becoming flat lines as you can see in the picture.

This is even after trying to send it by setting the highest possible image quality settings.

I would like to know if there a setting i need to look for while converting OR instructions which i need to let my machine shop.

The smoothness of the profile is the most important thing for the part.

Thank you

When exporting .dxf/.dwg (Save As) set the option to save splines as splines.
Instead of Save As from model, create a drawing and do the Save As from there.

The "options button" is at bottom of Save As dialog box.

  Thank you for the the tip Kenneth. This is in case of a dxf. But is there any thing specific for IGES or STEP

    Both of those formats have options as well.
    
    Try IGES with 3D wireframe curves (2 options).
    Also try with Solid/Surfaces unchecked (wireframe only).
    
    The workaround, although painful, might be to create a drawing with all the views you need and export to .dxf
