Why does CAD matter so much compared to a PDF scan?

A CAD file or vector PDF can be traced directly at true scale. A scan has to be interpreted, scaled manually and checked against written dimensions, which adds hours per plan and introduces the risk of error. Locating the CAD file is usually the highest value step in the whole handoff.

What happens if I send an outdated drawing set?

The error is normally not caught until the first review, by which point the modeling is complete and wrong. That means restarting rather than revising. State the revision number and date in writing, and notify the studio immediately whenever a new set is issued during production.

How much furniture direction is enough?

Three or four sentences plus two reference images. Say the market positioning, whether the palette is warm or cool, and anything you specifically want avoided. Without it the first review becomes a conversation about taste rather than accuracy, which consumes a revision round you could have kept.

Why nominate a single reviewer?

Because separate feedback from three people is normally billed as three revision rounds, and contradictory notes force the studio to stop and ask who decides. Consolidating through one named person typically saves more calendar time than any improvement in production speed could deliver.

What to Send Your 3D Floor Plan Vendor

Three dimensional floor plan of an apartment with dimensions and room labels prepared from a complete architectural handoff

Send the current dimensioned plan in CAD or a vector PDF, a written note of the revision number and date, ceiling heights per space, any elevations or details that affect what is visible from above, a short furniture and finish direction, the list of unit types you actually want drawn, and the name of the single person who will approve. That package removes almost all of the back and forth that turns a five day project into a three week one.

None of this is exotic. It is simply the information a studio would otherwise have to ask for one question at a time, with a day of latency on each question.

Drawings, in the right format

A CAD file or a vector PDF can be traced directly. A scanned or photographed plan has to be interpreted, scaled by hand and verified against dimensions, which adds hours per plan and introduces error. If CAD exists anywhere in your organization, find it before sending the raster version, because that single step is usually worth more than any other item on this list.

Revision number and date, stated in writing rather than only in the file name
Ceiling heights per space, especially where they vary
Elevations or millwork details for kitchens, baths and built ins
Site plan or an orientation note if you want a correct north arrow

Say which revision is current

The most costly failure in this work is modeling from a superseded set. It is not detected until review, and by then the whole plan is wrong. Stating the revision explicitly, and telling the studio immediately when a new one is issued, prevents a restart that no amount of production speed can recover.

Furniture and finish direction

You do not need a specification. You need three or four sentences and ideally two reference images. Say the market positioning, whether the palette is warm or cool, and anything you specifically do not want. Without direction, a studio makes a reasonable guess and the first review round becomes a taste conversation instead of an accuracy check, which costs you a full round.

Tell us which plans you actually need

Send the unit mix and mark which types are being drawn. On conversions and irregular buildings, the count of genuinely distinct plans is often higher than the count of unit types, which is worth resolving before pricing rather than after. Our note on adaptive reuse plans covers why that gap appears.

Name one reviewer

Feedback from three people arriving separately is three revision rounds under most agreements, and when the notes contradict each other the studio has to stop and ask who wins. Nominate one person to consolidate. This single decision is usually worth more calendar days than any production improvement.

State the real deadline

Give the date the plans are needed and what they are needed for. A launch, a broker package and an investor meeting have different tolerances for a draft. Scheduling backward from a stated date normally avoids a rush fee entirely, and it lets the studio tell you honestly if the date is not achievable while you still have time to adjust. Timing expectations are covered in how long a plan takes.

Our 3D floor plan services start with this checklist as a short intake form so nothing is discovered halfway through. Request a quote and attach whatever you have, even if it is incomplete.
