About this Web App
What does Construction Drawings & Calculations Generator include, and what changed from the native source?
Turn residential project inputs into locally generated vector drawing studies, calculation comparisons, editable cost scenarios and a saved project workspace. Ports the native vector-generation engine for local browser use. Corrects story/layout and sheet-index inconsistencies, opening schedules, selected wall thickness, window orientation and several calculation assumptions. Adds detached-garage concepts, multiple saved projects, editable cost scenarios and backups. Replaces unsupported native compliance verdicts with independently entered target comparisons and project-review topics. Simplified block-load models are not Manual J/S/D, member references are not verified structural capacities, and generated drawings are educational concepts. Browser printing provides PDF output. All drawing geometry is generated locally; no gallery collection is bundled.
