The way the DWG importer treats bezier curves is rough. You have more control of the result if you first add a lot of control points and straighten the segments in Illustrator before exporting to DWG or DXF.
Go to Object>Path>Add Anchor Points. (by default when you click this it adds an anchor point in the middle of every other anchor point you have) The smoother you want your curves the more Anchor Points you will want to add.
Then go to Object>Path>Simplify and check the “Straight Lines” box. Bring your “Angle Threshold” down to 0. You can check the preview box and see how it looks.
Thank you, This is exactly what I want to learn. Now I know how to check vector file before export to dwg. After adding more anchor points, import curve look better. However for best smooth curve, export to pdf first will provide most smooth result.
It is good to know, so I can have different workflow to choose, some times I don’t want to have too high poly to work with.
How can I get just plan arcs from Autocad to not come in so boxy? They are not splines but come in as like arcs with 2 sides and it is a mess…I tried the set to meters thing and that didn’t fix the arcs.
