Clear answers about editing, 3D updates, rendering, AI generation, exporting, and workflow.
What is ZDraw?▾
ZDraw is a desktop, web based design workspace for quickly laying out spaces, previewing them in 3D, and producing high quality renders, ai enhanced images, AI animations and 2d floor plan documents — ZDraw is designed for speed and clarity.
Why ZDraw?▾
Quick, fun, easy to use, and web-based — so you can use it anywhere. No install needed. Share your designs and artworks freely. Edit your designs in real-time. Import your GLBs for inspection. Render your GLBs for presentation. Edit your images using our third-party AI generators.
Who can use ZDraw?▾
Anyone can use ZDraw. You do not need any 3D modeling skills to use this application successfully.
How does 2D editing connect to the 3D view?▾
Your 2D plan drives the scene. When you draw or adjust walls and objects in 2D, the 3D view updates to match (and supported 3D transforms can update 2D).
What units does ZDraw use?▾
ZDraw is built around real-world scale (commonly millimetres). For imports/exports, keep units consistent so sizes and placements match expectations.
How do I save and load a project?▾
Save your work as a .zdraw file. Loading restores your plan, object placements, and key scene settings so you can continue editing.
What’s the difference between the Gallery and the Project file?▾
A project file (.zdraw) stores your editable scene. The Gallery stores rendered outputs (images) for review, sharing, and reuse.
How do I get cleaner path-traced renders?▾
Start with a good HDRI, increase samples for finals, and keep lighting simple. If noise persists: reduce extreme gloss, avoid tiny bright emissives, and use denoise when available.
Does ZDraw support glass/metal materials?▾
Yes. You can apply special material styles (glass/metal/glow) and paint faces quickly. For path tracing, balanced roughness and realistic brightness reduces noise.
Can I import my own 3D assets (GLB/GLTF)?▾
Yes. You can import GLB/GLTF and FBX assets, place them, and adjust transforms. For best results, ensure pivots and scale are sensible and textures are not excessively large.
Can I export my scene?▾
Yes — exporting (commonly GLB + textures) is supported for sharing, external rendering, or moving the scene into other tools.
Why does my scene feel slow?▾
Performance depends on asset complexity, texture sizes, and active render settings. For speed: reduce heavy assets, limit large textures, and keep PT samples low while editing.
How do AI credits work?▾
Each AI generation costs 1 credit Every newly registered member get 20 free credits on registration. You can view and manage credits from your Account area.
I found a bug — what should I include when reporting it?▾
Include: what you expected, what happened, steps to reproduce, browser + OS, and (if possible) the .zdraw file or a short screen recording.
