CAD Hatch Pattern Scale Optimizer

Prevent CAD viewport freezes and drawing size bloat. Calculate the mathematically optimal HATCH scale factors for metric/imperial viewports.

Input parameters (Parameters)

1. Current drawing unit of the drawing (Drawing Unit)

2. Target print scale denominator (Scale 1:X)1 : 100

3. CAD Pattern

4. Debugging HATCH scale factors (Scale Input)1

Optimum Hatch Scale Verdict

Optimal HATCH Scale

100.000

In the CAD Fill dialog box "Scale" Enter this value in

Safety Scale Range

10.000 to 1000.000

If it is lower than the minimum safe ratio, it will easily cause the drawing to freeze and collapse.!

MAXHATCH Too Dense

The density of line segments is extremely high! Easy to trigger AutoCAD MAXHATCH limits (default 100,000 lines), this will cause the drawing to be saved and stuck., Viewport crashes or casts to Solid fill.

Live Hatch Canvas ViewportViewport Size: 100mm x 100mm

Crash principle tips: In AutoCAD in if Hatch If the ratio is too small, the software will automatically trigger `HPMAXLINES` (Default 100000) Alerts. To prevent crashes, CAD will force the fill to render as solid (solid color), or cause a computational deadlock lasting several minutes. Be sure to use the safety bounds provided by the optimizer!
