Send Floor Plans for 3D Rendering: What to Include
Quick answer: Send a vector PDF or DWG of every level that appears in a view, with dimensions or a scale bar, openings, stairs, fixed elements and a north arrow. Mark camera positions if you can.
Why the floor plan comes first
The floor plan is the document a rendering studio opens first, because it defines the footprint, the layout and the relationships between rooms. Everything else hangs from it. Walls, doors, windows, stairs and fixed equipment are drawn to scale, and from them a modeler can build the base of the 3D model quickly and check it against the other drawings.
A plan is also the fastest way to spot a problem. If a corridor is narrower than a door swing, if a stair does not fit or if two rooms overlap, it shows up on the plan long before it shows up in a picture. Sending clear plans is the single most useful thing you can do to reduce revision rounds.
What a good floor plan for rendering contains
- Every level that appears in a view. If the camera will see the second floor through a double-height space, we need that level too.
- Dimensions or a stated scale. A scale bar or a few dimension strings let us confirm size.
- Door and window locations and sizes. Openings decide light and views.
- Stairs, ramps and level changes. With rise and run or an indication of the number of steps.
- Fixed elements. Kitchen cabinetry, bathroom fixtures, fireplaces, built-in shelving.
- Room names. They tell us what each space is for and how it should feel.
- North arrow. It fixes orientation for light.
Furniture is welcome but not required. When furniture is drawn, we treat it as a suggestion unless you tell us it is final.
PDF, DWG or a photograph
A vector PDF exported from CAD or BIM software is the everyday standard. Lines are crisp, text is readable and measurements can be taken from it. A DWG or DXF file is better still, because it carries exact geometry that can be imported directly. Send both if you have them, since the PDF is the reference that tells us which layers were meant to be visible.
A photograph of a printed plan is the weakest option, but it can work. Lay the sheet flat, shoot from above, avoid shadows and include a scale bar or write one known dimension on the sheet. Skewed photos lose scale at the edges, so we usually calibrate from two dimensions in different directions. Tell us it is a photo, so we plan for the extra check.
Scale, sheet size and readability
A plan printed on a large sheet and reduced to letter size in a PDF may be unreadable. Check that text is legible at 100 percent zoom and that dimension strings can be read without a magnifier. If the drawing set has several plans on one sheet, tell us which is which. If a plan was drawn at a stated scale, such as 1/4 inch to one foot, keep the scale note on the sheet. When a PDF has been printed and scanned, the scale printed on it can no longer be trusted, so send a known dimension instead.
We also ask for the original page size of the sheet, because a set exported at one size and shared at another changes what a scale bar means. It sounds like a small point, but scale errors are among the most common causes of wrong proportions in early previews.
Plans for multi-story buildings
For buildings with several levels, send every plan, named clearly: "Level 1", "Level 2", "Roof plan". If the levels stack simply, the studio can align them by common walls and stairs. If they are offset, add a note or send a section, since a section makes the vertical relationship obvious. Roof plans matter even for interior projects, because the roof shape affects ceiling heights and daylight.
For projects with a basement or a parking podium, tell us whether those levels will appear in any view. If they will not, we skip modeling them, which saves time.
Furnished plans versus empty plans
A furnished plan shows how the owner or designer imagines the space to be used. An empty plan shows only the shell. Both are useful, but they answer different questions. For a marketing image of a model apartment, a furnished plan tells us exactly what to place. For a permit image, an empty shell may be all that is required.
If your plan contains furniture that is only a placeholder, say so. Otherwise, we may model a sofa that you never intended to buy, and the client may start asking about it. Conversely, if furniture is final, send the product list so we can match style and scale.
Marking up a plan to show your intent
A simple markup can save several emails. On a copy of the plan, draw the cameras as small arrows with an angle of view and label them with a number. Circle areas that will be seen closely. Cross out areas that will never appear. Add short notes in the margin about finishes, such as "oak floor" or "white plaster walls".
You can do this in a PDF viewer or on a printout that you photograph. The markup does not need to be neat; it needs to be clear. A plan with numbered camera arrows and a list of the corresponding views is one of the most efficient briefs a studio can receive.
Common problems with floor plans
- Outdated plans. The set was changed after the plan was exported.
- Conflicts with elevations. Window positions on the plan do not match the elevation.
- Missing dimensions. The scale is unknown or lost in printing.
- Hidden layers. Notes or furniture that were meant to be hidden appear on the PDF.
- Unclear stairs. The direction of travel or the number of risers is not shown.
- Different levels mixed on one sheet. No labels to tell them apart.
Most of these are found in the first review and resolved with a short question. The danger is when they are not found, and the mismatch appears in a finished image.
A worked example: a two-bedroom house
A homeowner is planning a small addition and has a PDF from their designer with one plan, drawn at 1/4 inch to one foot. They send it along with a photo of the existing kitchen. The studio opens the plan, checks the scale bar and discovers that the PDF page was shrunk on export, so the scale bar reads correctly but the text is small. It measures from the dimension strings instead and confirms that the addition is 14 feet by 16 feet.
It marks two possible camera positions on a copy of the plan and sends it back, asking which one the homeowner prefers. The homeowner picks one and adds a note that the window over the sink is 4 feet wide. The model is built in a short session and the first preview matches the plan to the inch. The whole exchange took a few messages and prevented a resizing error.
Naming and organizing the files
A tidy folder saves more time than most clients expect. Name each file after what it shows, for example "Level 1 plan", "Level 2 plan" and "Roof plan", and add a date or a revision letter so nobody has to guess which version is current. If you have two design options, put them in separate folders with the option name in the folder title. Studios often receive twenty files with names like "scan0004" and lose an hour matching them to the drawings they describe.
Include a short text note in the folder listing what each file is and which one wins when two disagree. If the architect sent a revision after the first set, say which sheets were replaced. This sounds administrative, but it prevents the classic problem of building a model from a superseded plan.
Plans for interiors versus exteriors
For an exterior view, the plan matters mostly for the footprint, the projections and the roof outline. Interior furnishings on the plan are irrelevant, and we will ignore them. For an interior view, the plan is the source of the room geometry, the door swings, the built-ins and the sightlines. A plan that shows the kitchen island, the pantry door and the window wall lets us place the camera with confidence.
If you need both, send the same plan and tell us which rooms are in view. We then model those rooms in more detail and simplify the rest, which keeps the cost fair. You can see how this changes the work in our guides on interior stills and exterior stills.
What to send with the plan
- Elevations and at least one section, so heights are known.
- A site plan for exterior views.
- A finish schedule or references.
- A list of views and their purposes.
- Notes on what is final and what is open.
- The deadline.
Questions to ask a studio about your plans
- Will you review the plans and tell me what conflicts you find?
- Can you work from a scanned or photographed plan, and what does that change?
- Do you prefer PDF or DWG, or both?
- How do you handle furniture that is not final?
- Will you send me a marked-up plan with the camera positions?
Frequently asked questions
Is a PDF floor plan enough?
Yes, in most cases. A vector PDF with readable dimensions is the everyday standard, and a DWG adds precision.
Can I send a photo of a paper plan?
Yes. Lay it flat, avoid shadows and include a known dimension so we can calibrate the scale.
Do I need to include furniture on the plan?
No. Furniture helps for interior views. If it is a placeholder, say so.
How many floor plans do I need to send?
Every level that will appear in a view, directly or through an opening, plus a roof plan if the roof affects the views.
What if my plans are old?
Send them with a note about what has changed. We can update the model, and we list the assumptions for you to check.
Should I remove notes from the plan?
Not necessarily. Notes about finishes and heights are useful. Just make sure the PDF is the current version.
Do you need dimensions on every wall?
No. A scale bar and the main dimensions are enough. We cross-check against elevations and sections.
What if the plan and the elevation disagree?
We flag it and ask which one is correct before modeling continues.
