Hopefully i can describe problem better than topic title.:)
I have a DXF file creadted by a PCB software. The file opens fine in BobCad but what should be a closed polyline shape has a small .0004 line that will NOT chain select or be part of the CONTOUR operation. And even if i delete this line and connect a new line, i still can not do chain select and totally close the shape with CONTOUR operation.
In the file i attached there is a pointer showing where one of these (green)breaks/lines are located. You have to zoom in to see it.
Any ideas what is causing this?
Using BobCad Pro V26.
Thanks for any info,
To clean-up the drawing a bit,I would run clean-up/re-organize and follow up with an Arc Fit command.
I tried the clean-up/re-organize before but it made no difference. Hoping i can find out the problem, as i have another PCB i would like to make that has a bit more traces and pads….would be mind numbing to manually fix each one.
did you do the arc fit command ?
You could also use trim extend 2 Entities
Did the arc fit, but now there are some little lines left that are not touching in anyway. see pic. Running Clean UP made no difference.
Trash can them
I was able to delete them by hiding all layers but the one these small lines are on.
But still have same issue, that the shapes are still not fully closed contours.Problem is at the same place…really strange.
Here is your 1st file back.I did a trim and extend 2 entities
I posted in the DipTrace forum to see if its something on there end off how there Import and Export is handling the file.
I think this kind of problems should be related to the export from your pcb software.
Anyway BobCad is not designed for pcb contouring, try a dedicated software and see if it works better.
The best should be CircuitCam ( a bit expensive ). Have a look also to CopperCam.
Strange thing is i used BobCAD for another PCB about a year ago with no problems at all. The only change was a new version of DesignSpark.I use this to design PCB and export Gerber file. Then use DipTrace for DXF export.
I have tried CopperCam…its not to bad….just dont like the toolpaths it creates, especially the zig-zag clearing toolpath.
Really wish BobCAD would import a gerber file.
Anyhow,Right now iam trying FlatCAM for my PCB work. Dont look bad, but its still under development.
