SOCSS

SOCSS is a general-purpose 2D CAD and graphics app for Mac. It combines technical drawing tools with graphics features for creating presentation materials and flyers, and includes input assistance and functions for architectural drafting.

Its graphics tools include Bézier curves, gradients, shadows, clipping, blending, and masks. These let you add visual detail to drawings and create graphics alongside CAD work.

AppleScript support lets you customize and extend the app. Scripts can handle tasks such as calculating areas and printing addresses. Downloadable drawing examples and scripts provide starting points for drafting workflows.
