Practical writing on directional sign design — coordinates, bearings, materials, typography, and the CNC details that decide whether a sign reads well outdoors. New articles are added as projects come up.
Designing Fingerpost Signs That Match Real Geography
A bearing-accurate fingerpost reads differently from a symmetrical decorative one. Here is how to plan it, and what most people get wrong before cutting.
GPS Coordinates and True Bearings, Demystified for Sign Makers
Latitude, longitude, true vs. magnetic, great-circle vs. rhumb line. The minimum useful theory before you put a number on a wooden plate.
Choosing Materials for Outdoor Directional Signs
Wood, metal, composite, acrylic — and how each one constrains the dimensions, finishes, and lifetime of an outdoor directional sign.
Preparing DXF Files for a Clean CNC Cut
Layers, units, toolpaths, kerf, fixturing. The CAM-side details that decide whether a DXF becomes a clean plate or scrap.
Text and Typography on Directional Signs
Font, weight, tracking, and unit placement on a directional plate are functional decisions. Here is how to make them well.
From Coordinates to 3D Render: A Tervika Workflow
A real lakehouse project, end to end: choose destinations, iterate in 2D and 3D, export DXF for the shop, GLB for the client, PDF for the file.
