STEP 01
Measure the full occupied region
Start with the actual hardware and cabinet joint drawings, then compare them with a physical mock-up wherever possible. Include the body of a support, a hinge plate, fastener paths, a back groove and the swept space required to operate or service the hardware. A visible screw head alone is not the whole envelope. Measure the lowest and highest affected heights from the same finished bottom datum as the pin grid. Add whatever project-specific separation your hardware and construction require before recording the exclusion; the planner does not invent that clearance.
STEP 02
Use a conservative full-width band
Each entered keep-out extends across the entire depth of both panels. This deliberately omits front and rear holes at the affected heights, even if the physical obstacle occurs near only one row or one side. It keeps the remaining levels complete: every available height has a left-front, left-rear, right-front and right-rear hole. That choice may remove more adjustment positions than a custom engineered pattern would. The tool does not offer partial support sets or claim that three supports can replace four. If the project needs asymmetric rows, prepare a separate reviewed layout.
STEP 03
Include the hole radius at the boundary
The overlap test compares the complete vertical extent of each circular hole with each entered band. A center is blocked when center + radius reaches the band bottom and center − radius has not passed the band top. Boundary contact counts as a conflict. This geometry is useful when a center looks just outside a colored strip on a small screen. It still tests only a hole circle against your recorded band; it does not know the size of a pin shoulder, shelf notch or moving hinge. Include those additional envelopes when measuring the band.
STEP 04
Keep the original grid through the interruption
The first allowed center above a band is the next existing grid position that clears it. The tool never shifts the upper row segment to make a new first hole at the band edge. Preserve the same behavior in the shop: mark omitted jig bushings, bridge the gap with a verified reference or use the jig maker’s appropriate continuation method. A gap is not a new origin. Check the first and last centers after the interruption against the bottom datum before drilling the remaining side, especially when the jig has been unclamped.
STEP 05
Review the shelf and door together
Select an available level and install the actual support and shelf during the test assembly. Cycle the nearby door and inspect both the shelf edge and support bodies through the intended travel. Check rear engagement with the back installed and allow for whatever removal access the project needs. A successful circle-and-band screen does not evaluate moving clearances, bearing area or fastener capacity. Record the measured envelope and any added allowance in the notes so a later hardware substitution prompts a new review instead of inheriting an unexplained colored band.
Can I block only the front row?
This planner uses full-width bands on both sides so each remaining level has four corresponding holes. An asymmetric support plan needs a separate design review.
References and model boundary
The manufacturer references describe their own jig systems. Project dimensions, grid phase, keep-out envelopes and remaining-skin requirements belong to your measured setup. The planner tests its stated geometry; use the actual hardware instructions and a physical test pair before drilling production panels.
