DXF Roundness isn't round (small flat pieces)

[kobu83]

DXF opened in cambam, but the roundness isn't round.
 
When i open the dxf file in solidworks it have perfect roundness, when open the file in cambam (version 1.0) the roundness are many flat pieces.

What can i do? See picture.

Hello

Can you share the DXF itself ?

Not at home right now, will share it about an hour.

Have a look in menu item, Tools->Options->Arc Display Degrees.

If that is set too low then curves will look like polygons. A value of 0.1 works for me.

I might just add to Eddy's helpful comment that, for your own erudition, you should try several settings, including much MORE coarse as well as finer, just so you can visualize the effect it has.

As Lloyd said, try 20 and then 0.1.
Most important though, you must save the settings before they take effect, Tools->Save settings.

Sorry for late reaction, I have tried the things u all said but it didn't help to mee.

Here is the CB file so u can test what is wrom maybe.

I hope someone has the answer

I see now, when i draw a circle in cambam, and zoom in, this circle is also build of little flat lines...?

Having looked at the polylines in your file, they each consist of a series of STRAIGHT sections, none of them have "Bulge" which you need to create a curved line.

Please attach the dxf file you are using to see what that looks like.

Yes but only for the display, if you cut the circle, it's a true circle. (and if you convert the circle to polyline, the display is dependent of the value of "arc display degree" in the options ; I use 0.5° for this setting)

There is no setting for the circle display

CamBam must be restarted after arc display degree has been changed.

Arc Display Degrees

Arcs are displayed using multiple line segments. This setting defines the angle between each segment. Smaller numbers make smoother curves but slower display rates.

To put some curve (bulge) back in, select all the polylines then use menu item, Edit->Polyline->Arc Fit, with a tolerance of 0.1
