STEP 01
Identify the pair before creating a pattern
Give the two sides a shared cabinet ID and distinct left and right labels. Mark the inside face, finished front edge, top and finished bottom while the parts are still easy to compare. Put marks where they remain visible after a jig is clamped, or repeat them on removable tape beside the working area. Compare actual side heights and the intended assembly alignment. If one panel includes a different toe, notch or joint allowance, a shared panel-bottom datum may not represent equal installed heights. Resolve that construction difference before using this equal-panel model.
STEP 02
Read the map as two inside faces
Shelf Pin Studio draws both inside faces upward, with tops at the top of the page. The finished fronts face outward: the left panel has its front on the drawing’s left, and the right panel has its front on the drawing’s right. This is a labeled bench arrangement, not a command to flip a particular jig. Use the front arrows whenever moving between the drawing and the part. Symmetric front and rear setbacks can hide a reversal, so verify the labels even when the two row positions appear interchangeable.
STEP 03
Keep drawing coordinates separate from shop coordinates
The hole CSV names its axes directly. X is measured from that panel’s own finished front edge; Y is measured up from its own finished bottom edge. Both panels therefore have the same X and Y for corresponding holes. The SVG’s horizontal page coordinate mirrors the right side only to make the physical pair legible. Do not feed either export directly to a machine: machine origins, axis directions, tooling offsets, face selection and workholding are outside this model. A coordinate list needs a separate reviewed setup before any automated machining.
STEP 04
Check opposing centers before repeating holes
Use one paired test setup to compare a selected low level and a selected high level. Keep the front and rear rows on each side in that comparison. A constant mismatch suggests the wrong starting reference; a mismatch that grows with height suggests pitch or indexing trouble. Re-measuring only the first pair cannot detect accumulating error farther up the side. If the result is inconsistent, pause the series, label the questionable holes and investigate the reference instead of adding more positions that might later be mistaken for accepted ones.
STEP 05
Preserve the reference through edging and assembly
Finished-edge coordinates assume that the panel is already at the dimensions shown. Applying edge banding, trimming the bottom or changing a joint shoulder after layout can move the relevant reference. Set the production sequence so the reference exists at drilling time, or document a deliberate conversion on the shop drawing. Do not silently mix a raw blank on one side with an edged part on the other. Save a new revision when the finished datum changes, export a replacement hole list and withdraw the older print from the bench.
Why do the right-side drawing and CSV look different?
The drawing mirrors the right inside face. The CSV always measures from each panel’s finished front and bottom, so matching holes retain matching coordinates.
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.
