Frequently Asked Questions
Will delicate CAD hatchings and dimension text remain legible?
Yes. Lossless PNG compression ensures fine CAD hatch patterns, dimension callouts, and wall lines never suffer JPEG blur.
Are confidential construction plans and client blueprints uploaded?
No. Zero blueprint data leaves your device. All calculations occur strictly in local browser memory.
Can I render very large Arch D (24x36 inch) sheets to PNG?
Yes. The browser engine dynamically manages memory buffers to render large architectural sheets cleanly.
