While importing a DXF into the G-code generator, it does not import the complete file. Please see the photo. It drops a small segment of the circles out of the files and will not allow an offset operation. Have you seen this before, and what can I do to prevent this?
1) Make sure to convert all splines/arcs/etc to Polylines 2) Make sure your DXF is saved as DXF R14 PolyLine See docs:software:file-errors [OpenBuilds Documentation] to learn more
Sometimes one may need an intermediate CAD to clean up some of the more advanced CADs outputs. Here's one example, of how to use QCAD (free) to convert everything to Polylines: Problems with importing DXF into OBcam
I downloaded QCAD and ran the steps as you described them, and it did close the gaps in the circles (thank you!) but please have a look at the photo. It will import properly, but once I move it to position and try to scale it, I get the image you see in the photo.
Please provide a Workspace Export (File > Save Workspace (Export .obc file) ) of the file as loaded, before moving it. May need to zip the OBC file to attach to forum post if it complains about the file type
I am able to Move it (used Transform > Position > and set Left/Bottom to 0). I also tried moving it using the Move tool and the Mouse Then I selected Transform again, scale, and made it larger (width=200) - worked fine. Any specific steps / order of steps you used? Any chance you had loaded the non-polyline version of the file?
The hell am I doing wrong Are there any settings I may have inadvertently selected within the Openbuilds generator that might give me weird results?
No, nothing I can think off. If its a non -polyline or open vector the first coordinate can sometimes jump around that looks like your screenshot, that is an old bug - but usually relates to a file being loading with a spline/arc instead of a polyline
As an aside - you can make sure to export from CAD at the right origin and size to avoid having to do that in CAM.
(used Transform > Position > and set Left/Bottom to 0) <-------- I am not able to find these operations
Green square over the ruler icon on the left toolbar = transform tools Click the entity to transform Use the scale/position tabs to move, scale, etc the entity More reliable than the Move tool (blue square)
I just messed around with it, too and it worked or me. I resized it randomly to check that before positioning.
I have tried so many ways, but cannot get circles to close when I import the DXF. The attached photos show what the sketch looks like in Solidworks, then how it looks in the workspace. It only seems to dislike circles.
Make sure to convert all entities to Polylines: See docs:software:file-errors [OpenBuilds Documentation]
Yep...I used QCAD to convert as per your earlier advice, and it closes the circle but then I get this (just as before)
Thanks, yes this one does have a problem - logged a ticket on the OpenBuilds CAM github repo to have it looked at As a sidenote, the hexagon and rectangle are Lines not Polylines - so also won't work well. In the meantime, instead of Moving in CAM - move it in CAD to the correct origin, before exporting to DXF.
Moves with the Transform tool also works by the way. See post #14 above. Just mouse moves that has a bug it seems For now, we've removed the Move button from the toolbar - in order to force users to use the much better Transform tools instead
For now, we had a couple users complain about the removal of the Move tool (because it works great with their files). I am putting it back, and hoping you personally will avoid using it and rather use the Transform tool instead (which works with your sample files), or move your files in CAD (not CAM), or also consider other CAM options that may suit your workflow better. See docs:software:overview [OpenBuilds Documentation]
Could take a look at the attached "celebration" file that was modified using QCAD. I am also attaching original file. I am having a problem with open vector. Thank you...Richard
I am using Qcad. when circle is converter to poly, it gets a certain number of segments. How to increase number of segment. I see that objects within the openbuild CAM can control have number of segments. Can import DXFs be modified within openbuild CAM or someone knows how to change setting in Qcad?
Try Interpolate circle with polyline - QCAD.org Forum - didn't test myself, just first result on google
steps work within Qcad. went to max360 segmetns. When imported to openbuild geometry goes to default number of segments. let me know if anyone was lucky.
