Typical RC plane plans come in PDF multi-page format… with full-size, untiled plans often being 20" x 30" (508mm x 762mm) or larger. Different cut lines are usually color-coded and some are dashed lines… red (for scoring cuts), as in photo
Given the large drawing dimensions, each segment/gap of a dashed line may be ~10mm ( about 6.5mm segment + 3.17mm gap in this drawing)… but the segments need to be joined together to form one line and I’ve found no easy way to do that in LB.
A workaround is to import PDF into Inkscape, select all, and uniformly shrink (typically by one-half) the drawing dimensions so that the gaps in dashed lines is less than 2mm (max auto-join tolerance setting in LB). Saving as DXF in Inkscape, import into LB, and auto-join then works to join the red line segments into a single, unbroken, line. The drawing then needs to be enlarged to full-size again.
Popular Grbl-based CNC needle-cutters for foam sheet often use servo-driven Z-lift for cutter head… similar to pen-lift plotters. M3/M5 are the commands most used… and GRBL-M3 does a great job creating good gcode for cutters. But unjoined dashed line segments result in many unnecessary cutter up/down motions… whereas joining them allows for smooth line cuts.
I’ve searched unsuccessfully for a couple of days for ways to join these lines segments. Is it possible to do this in LB today? If not, can it be added? DXF auto-join works as long as the gaps in dashed lines is within auto-join tolerance… should the tolerance range be increased to allow full-size drawings to be properly handled? LB is fantastic… would be even better with this additional feature.
Thanks in advance.
