Five minutes through a typical job: bring in coordinates, generate holes, check clearances, number pins, export to CSV.
PlateDesignTools sits next to AutoCAD and controls it. The window has four parts:
Most operations follow the same pattern: prepare the input (select objects in AutoCAD or a cell range in Excel), click the action, answer any prompt that appears in AutoCAD's command line, then watch the status strip for progress (… N/M) and the result (✓ … or ✗ …). Only one operation runs at a time.
Either select existing geometry in AutoCAD, or import from Excel. For Excel, select the cell range including the header row; columns are matched case-insensitively against the aliases in Settings → Excel columns. The data shape is x, y, r for circles or x, y, w, h for rectangles, with optional pin no. and layer columns. See Operations › Holes & objects from Excel for the full format.
In the Holes section pick the action that matches what you have. Circle → Rectangle converts selected circles to rectangles of a given width/height at the same centers, on your hole layer. Objects → Circle centers copies a picked object onto every selected circle's center (bounding-box center lands on the circle center). Excel → Holes creates a circle or rectangle per Excel row. See Operations › Hole conversion.
Open Clearance (DRC), select the objects to check in AutoCAD, enter the minimum clearance in drawing units, and click Check. Every pair closer than that distance is highlighted with a polyline on the clearanceChecked layer (name configurable), and the status strip reports the number of collisions. Arcs / bulged polylines / circles are polygonised at the resolution set in Settings → Clearance (DRC). See Operations › Clearance check.
Pin numbers are text labels placed at each hole's center on the pin-number layer, with height = hole size × the ratio in Settings → Holes. If you created holes from Excel, the row's pin no. column is used. Otherwise, Hole info → CSV numbers the exported holes sequentially (1, 2, …) in sorted order and writes Pin No., x, y, r (circles) or Pin No., x, y, w, h (rectangles) — encoding and the optional coordinate transform (scale / mirror / offset) live in Settings → Output. See Operations › CAD → CSV.
DUT Array builds a grid of DUT cells from chip W/H, rows/cols and row/column skip — preview the outline, then generate. µm → mm / mm → µm rescales selected geometry by 1/1000 or ×1000. Rotate objects rotates each polyline/rectangle about its own center by a given angle. Full list: Operations.
