Terrain for your design.
Ready in minutes.


The detailed terrain made it easy to work with! It is great for saving time.
It saves time on architectural competition work, and the detailed modeling makes it convenient to use.
It saved an unbelievable amount of time on contours and terrain cleanup! Every time I started a project, creating site contours and adjusting terrain data used to wear me out. My workflow has completely changed since using Stura3D. It finishes the most labor-intensive contour work and layer organization in no time, so I can spend the time saved on massing design and site analysis. If contour work has been giving you headaches, this tool is a real lifesaver. Highly recommended!
좋아요 빠르게 과제를 할 수 잇어요 추천합니다.!!!!!!
A terrain model that could have taken me several days was produced quickly, which helped a lot. Aerial photographs are included too.
The layers are well separated, and I liked having detailed information and a satellite map included! The cadastral map and other information are easy to view by layer, which helped a lot with architectural design.
Using this alongside the LISP routines I already use seems to make terrain contours very quickly. It would also be convenient if buildings were split into layers by number of floors.
I used it very successfully for my graduation project. Thank you. I will keep using it regularly.
It was very convenient to reduce my working time while also being able to use the parts I needed for diagrams.
It is really great! It helped me reduce my working time a lot. I expect to use it regularly. Thank you!
So, so good, haha! I found it while looking for help because I was short on time. It is really good...
실제 설계일을하면서 콘타3d작업의 시간할애를 대폭줄여주는 대단한기술이라고 생각합니다 매우 편리하고 간편합니다.
I use it often because the details are well represented. Above all, raising contours and buildings one by one used to take a lot of time, and this is excellent for saving time!
I tried preparing the site in Grasshopper as usual, but it did not work properly with a larger area. With Stura3D, however, I got a perfect model in five minutes. The downloaded Rhino file is very detailed and neatly organized by layer, making it easy to use. It is also lightweight because it uses mesh surfaces.
Rhino is difficult, so I am downloading it again for SketchUp. My deadline was right around the corner and I was in a real rush. You saved me...
Good, I made good use of it. It is good. I am using it effectively together with AI.
The terrain creation process was simple and the output was clean, which helped reduce my working time. It was convenient enough for professional use as well.
I like how detailed the stepped terrain is. I was short on time and needed it immediately, and thanks to this I could use it right away!
Great working efficiency q(≧▽≦q) It was so convenient not to have to create every contour individually! I am satisfied because it saves time and greatly improves efficiency!
The contours, elevation differences and even natural erosion are represented with more detail than I expected. I am very satisfied: it allows much more natural level design than shaping the terrain by hand.
I downloaded terrain contours for another competition, and the quality is better than other sites again. I will keep using it.
Honestly, the heights of surrounding buildings are represented in greater detail than on any other site. I would like to use it a lot, but the cost of using it for every project makes me hesitate. Still, it is excellent and the best for saving time. I wish the price were lower and I could buy only the parts I need. For example, if I only need white box buildings, I would probably buy it for every project if I could pay just for those boxes.
Thank you for saving me working time. I tried it for the first time because I was short on time, and it is useful.
It is really fast and convenient, although the terrain sometimes comes out a little rough. Given the time involved in producing DWG files and models, I suppose that may be unavoidable.
It is great to receive a map in about five minutes for work that would otherwise take a day.
The output is nice and clean. I always find it useful.
It significantly reduced my working time, which let me focus on other tasks.
It is very convenient: not only the contours but also some of the roads are represented well.
It saves considerable time on site diagrams and 3D site models, and the high terrain accuracy makes it very useful.
It reduced the unnecessary time and effort spent creating contours and helped me work efficiently.
This really is a breakthrough... It is the best. I am so glad it saves time. Thank you.
The terrain is neatly organized, and even the road-line details are very good.
Getting terrain contours like this is such a great deal!!!
This is really good... It is great not just for 3D but also for 2D data. I practically cannot live without it now.

FAQ
Answers to questions that come up most often.
Previews & downloads
Q1.Can I download data for locations worldwide?
Yes. You can select and download locations worldwide using address search or the map. Available detail may vary by the coverage and quality of source data in each region.
Q2.What is the difference between preview and download?
Preview lets you check the location, area, and terrain shape first. CAD, Rhino, SketchUp, and GLB work files are generated through download after payment or credit use.
Q3.How many free previews can I create per day?
Each account gets three free previews per day based on Korea Standard Time (KST), regardless of account age. The allowance resets at midnight KST; after using it, wait until the next day or purchase a preview pass.
Q4.How long does preview generation take?
Preview generation takes about three minutes on average. Depending on the selected area and processing conditions, it can take up to about 20 minutes.
Q5.Is a preview use deducted if an error occurs?
No. If preview generation fails, neither the free preview allowance nor a preview pass is deducted. If a pass was deducted before the error is confirmed, it is restored automatically.
Q6.Where can I redownload generated files?
Completed files are available in My projects after login. Previews can be checked for 10 days from creation, and downloaded files can be redownloaded for 10 days from the first download.
Q7.How many sample downloads are available?
Sample downloads are available twice per week per account based on Korea Standard Time. Sample areas are fixed, and stepped samples may also appear flat in very flat regions.
Payments, passes & refunds
Q1.How do I pay for downloads?
Choose the file you need and pay for it as a single download. For larger areas, contact support@stura3d.com.
Q2.How do I purchase and use preview passes?
After using the three free previews available each KST day, you can purchase a preview pass with three total uses. Each pass is valid for 100 days from payment. The three-use pass costs ₩1,900 or $1.50.
Q3.How does the 5-use pass work?
You can buy a 5-use pass at any time. Each pass provides five downloads across 2D, smooth, and stepped terrain for 100 days from purchase. If you own several passes, the oldest purchase is used first. Issuing a completed-file download entitlement deducts one use; downloading the same file again does not. Passes do not renew automatically, and unused uses do not roll over after expiry.
Q4.Can I get a refund for a preview pass?
An unused preview pass can be refunded. A pass cannot be refunded after even one use.
Q5.How do I get a refund?
If the downloaded file has a quality issue despite a thorough review of the preview, we will assess the refund request according to the Terms of Use.
Supported data & files
Q1.What is the difference between smooth and stepped terrain?
Smooth terrain is a continuous 3D surface for site review, architecture, and landscape planning. Stepped terrain is stacked along contour lines and is useful for models or contour-style representation.
Q2.What source terrain is included with stepped downloads?
Stepped downloads include complete and area-based terrain by contour interval, plus contours. Supported formats also include area layers such as roads and rivers; choose smooth terrain only when you need a continuous surface.
Q3.How do I choose contour interval?
For smooth, stepped and 2D terrain, you can choose 0.5m to 5m in 0.1m increments.
Q4.What is included in DXF (CAD) files?
DXF files include contours, building outlines, roads, addresses, and cadastral information by layer.
Q5.What is included in 3DM (Rhino) files?
3DM files include 3D terrain, buildings, roads, and rivers as layers that open directly in Rhino. Stepped downloads include stepped terrain and contour work layers.
Q6.What is included in SKP (SketchUp) files?
SKP files include 3D terrain, buildings, roads, and rivers that open directly in SketchUp. Files are saved in millimeters and are prepared to open without conversion.
Q7.What are OBJ/STL files for?
OBJ and STL are useful when shape review matters most, such as rendering, 3D printing, or sharing with external tools. Material or layer data can be limited depending on the program.
Q8.What scale are downloaded files?
All files are generated at real-world 1:1 scale. SketchUp SKP uses millimeters, while DXF, 3DM, and GLB files use meters. OBJ has no unit metadata, but its coordinates use meters, so import it as meters. STL also stores no unit metadata and keeps the numeric meter coordinates unchanged. When a 3D-printing program reads those values as millimeters, 100% size equals 1:1000 scale; no additional reduction is needed.
Q9.How do I import 3D DXF into Archicad?
Do not open the DXF directly. In an Archicad project, choose File > Interoperability > Merge..., select the 3D DXF, and enable Import Model Space content as GDL object. Set Scale X/Y to 1.00, merge the file, then use 3D > Generic Perspective and View > Zoom > Fit in Window. The terrain uses meters, and the ZIP includes a short usage guide.
Q10.How do I use GLB downloads?
Choose smooth or stepped terrain, preview and complete checkout, then download GLB from My Projects. Import it with Blender glTF 2.0; no Stura3D plugin is required.
Q11.Can I use the data for surveying?
No. Stura3D data is provided for design and planning review, not surveying. Elevated roads are included where supported by source data, but survey-grade accuracy is not guaranteed, and some bridges, tunnels, and caves may differ from reality.
Q12.Roads do not align with the terrain or satellite imagery.
Roads and elevated roads reflect their height and shape where supported by source data. Satellite imagery maps a top-down 2D image onto the terrain surface, so an elevated road may also appear on the ground below it. Different capture and update dates can also cause roads and buildings to appear misaligned.
Account management
Q1.How do I delete my account?
Sign in and open My Projects > Account > Delete account, then re-enter your account email. Email-password accounts must also confirm their current password. Download the files you need first: deletion restricts sign-in and project access. Payment and dispute records may be retained as required by law.
Q2.How do I change my password?
Open My Projects > Account > Change password. Enter your current password and a new password of at least eight characters. If you forgot your password, request an email reset link on the sign-in page.
Q3.How do I apply for an academic partnership?
Submit a student council or university partnership application through Customer Support. Applications must come from the organization’s representative or an authorized contact. Our team will review it and notify you of the result.
Q4.Where can I get a partnership verification key?
After approval, Stura3D emails the key to the applicant representing the organization. Members should obtain it from that representative, such as their student council president, and enter it in Account management.
