The short answer: which of the 5 takeoff programs suits which kind of job
Five help pages show how these takeoff programs set scale and which limits they state.
Key takeaways
- Verify scale accuracy before drawing. On-Screen Takeoff advises against changing page scale after takeoff is drawn because it may not resize all takeoff correctly, according to ConstructConnect.
- Check file page limits before uploading. The Buildxact Takeoff Tool supports a maximum of 20 pages in a plan file, according to Buildxact.
- Confirm scale calibration manually. Togal.AI states the system does not test the correctness of the scale, according to Togal.AI.
- Review supported file formats. Togal.AI notes CAD files such as .DWG and .DXF are not directly supported, according to Togal.AI.
- Use point snapping for vector PDFs. Set Scale or Calibrate requires snapping to two points during calibration for vector-based PDF sheets, according to Autodesk.
Check these five points against your specific plan set before starting a takeoff.
Bluebeam’s page notes that page-level calibration sets the scale for a single sheet. This approach is ideal when different pages in a PDF set were produced at different scales or with different units, according to Bluebeam. This suits projects where individual sheets vary in scale.
ConstructConnect’s page states that if a drawing has several regions drawn to different scales, you must duplicate the Page and set each copy to a different scale, according to ConstructConnect. This workflow fits drawings with mixed-scale regions on a single sheet.
Buildxact’s page says you can choose to apply a scale to a single page of your plans or to the pages throughout, according to Buildxact.
Togal.AI’s page notes that the system does not test the correctness of the scale, according to Togal.AI. This places the verification responsibility on the user for any job type.
Autodesk’s page states that before you can perform takeoff on a sheet, you must specify its scale, according to Autodesk. This requirement applies to any sheet being measured.
Match the scale setup method to your plan set’s consistency. If your PDFs have mixed scales across sheets, look for page-level or duplication workflows. If your sets are uniform, look for global application options.
How we compared: five publishers' own help pages and what we looked for
This section explains the method used to gather information for the comparison. We examined the specific help pages provided by each publisher to understand how they describe scale setup and stated limits. The goal was to isolate what each product explicitly states about its capabilities and constraints, rather than relying on general marketing descriptions or third-party reviews.
For ConstructConnect, the help page titled "On-Screen Takeoff - 06.01 What is Scale and Why is it so Important?" provides a definition of how scale works in the software. It states, "So if you draw a line that's 1" on the screen, it represents, say, 10' on the plan." according to ConstructConnect. This quote clarifies the relationship between screen measurements and real-world plan dimensions. It serves as the baseline for understanding how the tool interprets user input relative to the drawing scale.
For Togal.AI, the help page titled "Setting up the Scale" addresses the application of scale across multiple pages. It notes, "You can’t manually apply one scale to the whole set, as this could lead to inaccuracies." according to Togal.AI. This statement highlights a specific limitation or caution regarding bulk scale application. It indicates that the software treats scale setup as a page-by-page or context-by-context action rather than a single global setting for an entire plan set.
How each program sets and checks the drawing scale
Scale setup varies by how each tool handles single sheets or entire plan sets.
Bluebeam Page-level calibration sets the scale for a single sheet, which is ideal when different pages in a PDF set were produced at different scales or with different units, according to Bluebeam. This approach treats each sheet independently during the calibration process.
ConstructConnect If you come across a drawing and there are several regions on that drawing that have been drawn to different scales, you must duplicate the Page and set each copy to a different scale, according to ConstructConnect. The tool requires page duplication to manage mixed-scale regions within one drawing.
Additionally, the publisher advises against modifying scale after takeoff work has begun. We do not recommend changing the scale of a page after you have drawn takeoff because On-Screen Takeoff may not be able to resize all takeoff correctly, according to ConstructConnect. This guidance applies specifically to the manual scale setting process described on that help page.
Buildxact You can choose to apply this scale to a single page of your plans or to the pages throughout, according to Buildxact. This option allows the user to decide whether the scale setting affects one sheet or the entire document during setup.
Togal.AI However, the system does NOT test the correctness of the scale, according to Togal.AI. The help page explicitly states that the software does not verify if the entered scale is accurate, placing the responsibility for scale accuracy on the user.
Autodesk Before you can perform takeoff on a sheet, you must specify its scale, according to Autodesk. This requirement makes scale specification a mandatory prerequisite before any measurement tools can be used on a given sheet.
Check the scale on a known dimension before starting takeoff.
What each help page says about limits: file types, page counts and plan types
The help pages for these five programs specify distinct constraints regarding file formats, page counts, and plan types. These limits determine which drawings a user can process and which automated features are available for specific subscription tiers or software versions.
For ConstructConnect, the "On-Screen Takeoff - 06.02.01 - Takeoff BOOST™'s AI-Powered Auto Takeoff - Overview and Requirements | Community" page outlines specific restrictions for its automated tools. Customers on an Essential or Plus subscription can run Auto Takeoff on 5 Projects, according to ConstructConnect. The same page states that Auto Takeoff supports floor plans and enlarged floorplans, it does not support Detail, Section, or Elevation plans, at this time, according to ConstructConnect.
Buildxact provides two separate help articles detailing different limitations. The "Using the Buildxact Takeoff Tool | Buildxact Help Center" page notes that the platform supports a maximum number of 20 pages in your plan file, according to Buildxact. A different article, "How do I use the Blu: Takeoff Assistant? | Buildxact Help Center," specifies that auto measure works for floor plans only, not roof plans or elevation, according to Buildxact.
Togal.AI addresses file format compatibility in its "Supported File Types | Togal.AI Help Center" article. This page explicitly states that CAD files such as .DWG and .DXF are not directly supported, according to Togal.AI.
Bluebeam's "Improve takeoffs with Quantity Link | Bluebeam Technical Support" page links a specific feature to a licensing requirement. For Revu 20, you must have a Revu eXtreme license, according to Bluebeam.
These stated limits highlight that automated features often apply to specific plan types, such as floor plans, while excluding others like elevations or details. Users should verify these constraints against their specific drawing sets and subscription levels before selecting a program for a new project.
Filled reference table: one row for each publisher
The table below summarizes how each publisher describes setting the drawing scale and the specific limits stated on their help pages. Each row reflects only the information provided in the linked source.
Check the linked help pages for any additional details not captured in this summary.
Illustrative example: checking a small plan file
Picture a plan file of 20 sheets. You measure 5 of those sheets in this walk-through. On one sheet, a line that is 1 inch on the screen stands for 10 feet on the drawing. A second region on that sheet was drawn at another scale, so you duplicate the sheet and set each copy before you draw. After the lines are drawn, you leave the scale as it is. You also set the scale on a sheet before any measurement starts. You repeat that check on each of the 5 sheets. These round numbers are illustrative.

FAQ: choosing a takeoff program
Which takeoff program should I try first?
Your choice depends on the specific plan types you measure and the file formats you receive. Check which program’s help page addresses your exact needs before starting.
Do I have to check the scale myself in every program?
Togal.AI states the system does not test the correctness of the scale, so you check the scale yourself on that program, according to Togal.AI.
Can these programs read CAD files directly?
Togal.AI notes that CAD files such as .DWG and .DXF are not directly supported, according to Togal.AI.
What do the auto-measure features cover and not cover?
Buildxact explains that auto measure works for floor plans only, not roof plans or elevation, according to Buildxact. ConstructConnect specifies that Auto Takeoff supports floor plans and enlarged floorplans, it does not support Detail, Section, or Elevation plans, at this time, according to ConstructConnect.
Can one scale be applied to a whole plan set?
Togal.AI says you can’t manually apply one scale to the whole set, as this could lead to inaccuracies, according to Togal.AI.
