Speedmodeling Leaderboard - 2025 RULES
TooTallToby’s Practice Models
SPEEDMODELING Leaderboard RULES:
Welcome to the world of 3D CAD Speedmodeling! By practicing and practicing again (and then re-practicing again), you'll learn some valuable skills and workflows that may be implimented into your daily CAD habbits!
And of course, through the gamification of 3D CAD, we hope you have some fun along the way!
Now is your chance to show off your speedmodeling skills - to the WORLD!
In the TooTallToby Speedmodeling Leaderboard challenge, you'll be tasked to:
1. Practice creating a model until you can do it in a speedy and efficient way
2. MAKE A RECORDING of your run
3. Post this recording online, and then post the link on the TooTallToby.com platform
Here's a guide to make sure your post is valid!
MAIN RULES / CHECKLIST:
1. The CLOCK must be shown during the entire run to ensure there is no "Time Manipulation" or editing
2. You may start a new part and set the UNITS and MATERIAL, BEFORE starting the CLOCK (to ensure fairness across different CAD systems)
3. You must begin your first sketch/feature AFTER starting the CLOCK
4. You must CLEARLY show the calculate mass, in your CAD system, before submitting your answer - CLEARLY...as in "we can see it in the video".
NOTE: You can use a script/featurescript/sensor or similar tool, to quickly calculate the mass - for more on this see this blog (link coming soon)
5. You must submit your answer in the TooTallToby Practice Models app. The time recorded in the app will be your official time for the speedrun
6. You must show the PURPLE SCREEN at the end of your video, confirming your time and the correct answer
7. NO IVAN EXPLOITS!! The model must be constructed to match the print.
DETAILED GUIDE:
- Practice as much as you want before recording.
- Use a screen recording program like OBS to capture the recording of your SPEEDMODELING run
- Before recording, position your screen as shown:
- During your run:
- The SPEEDMODELING video should begin with you pressing the “Reveal Drawing” button in the TooTallToby Practice Models app, which will start the clock
- The SPEEDMODELING video should end with you showing the PURPLE SCREEN, confirming your time and the correct answer
- The CLOCK from TooTallToby.com must be clearly visible throughout the entire run (all digits)
NOTE: You may use CTRL+Middle Mouse Wheel to zoom the webpage, to make the clock smaller
- The SPEEDMODELING video should show your entire run, unedited and with no TIME MANIPULATION (no cuts, no speed ups, no slow downs)
- The MASS of your model must be clearly visible in your CAD system and READABLE ON SCREEN, before you submit your answer
- OPTIONAL - Edit in post processing to add overlays/music/etc...
- OPTIONAL - Include voice narration, include video camera footage of your face or hands
- BEFORE starting the CLOCK, you may create a blank (empty) part and you may set your UNITS and ASSIGN A MATERIAL (density) for this model
This rule was added to ensure fairness across different CAD platforms, as some CAD systems take a few moments to create a new template and assign a material, while other systems allow you to assign materials and units directly in the part templates. Similarly users of some systems could EXPLOIT this rule by setting their “default units and materials” to one specific density, before beginning the run.
- You may begin your first sketch or feature AFTER starting the CLOCK.
No pre-created geometric data is allowed. No Drag and Drop library features allowed. No macros are allowed for feature creation. (If you have questions about a macro, ask by using the Contact Toby link in the NavBar on tootalltoby.com and Toby will answer).
You must create all the geometry for these models, AFTER starting the CLOCK.
- Hole Wizard (or equivalent hole tool) is allowed. However, this must come from a library of various selectable sizes. You may not create a “library feature” for this specific challenge, and drag and drop it onto the model.
- No IVAN EXPLOITS ALLOWED (see video COMING SOON). Since you can practice many times before creating your video, we expect that the geometry of your model will perfectly match the specifications in the 2D Drawing.
- You must CLEARLY show the correct mass of each model, before moving on to the next model. The mass must be shown in the CORRECT UNITS. The mass must be shown with the CORRECT PRECISION (or with a MORE PRECISE number of significant digits).
- Post your recording on Youtube.com. We will only validate videos posted on youtube.com. The vidoes may be listed publicly or unlisted, but cannot be set to private. Then enter a link to the SPEEDMODELING video in analytics page of this challenge (this page will only be available after the challenge is successfully completed).
- By submitting your video to the TooTallToby SPEEDMODELING Leaderboard you grant TooTallToby and team the right to use the video footage of your submission for any marketing/promotional purposes without limitation.
- You may submit one single SPEEDMODELING Leaderboard video per CAD System, per challenge. At any time, you may REMOVE the url for a video representing a slower time, and add a URL for a video representing a faster time. However, you may not submit 2 videos representing the SAME CAD system, for the same TooTallToby Practice Models challenge.
For example: You may submit a SPEEDMODELING video URL for a speedrun demonstrating Fusion360, and another SPEEDMODELING video URL for a speedrun representing Onshape, for the same TooTallToby Practice Models challenge.
- The fastest 20 times, for each TooTallToby Practice Models challenge, will be shown on the SPEEDMODLEING leaderboard.
Good Luck!
TECHNICAL DETAILS:
1. You CAN create a new empty part/document BEFORE starting the clock. This part may have the UNITS and MATERIAL set, BEFORE starting the clock.
However, this new part/document must have a GEOMETRICALLY BLANK CANVAS in CAD.
This means:
a. DEFAULT REFERENCE GEOMETRY:
i. The new part/document CAN ONLY CONTAIN the “default reference geometry”: Front Plane, Top Plane, Right Plane, Origin, etc…
ii. This new part/document CAN NOT CONTAIN any custom planes, axes, points, etc…
iii. This new part/document CAN NOT CONTAIN any sketches, features, surfaces, etc…
iv. You CAN NOT BEGIN the challenge having already entered SKETCH MODE.
1. You must begin creating your first sketch/feature AFTER starting the clock.
b. UNITS/MATERIALS:
i. This new part/document CAN have the units (mm, gram, inches, lbs, etc..) specified BEFORE starting the clock.
ii. This new part/document CAN have the material and/or material density specified, BEFORE starting the clock.
c. MACROS/CUSTOM TOOLS
i. Generally speaking, macros and custom tools are allowed.
However, they must be macros/custom tools that are available for general use, and not specifically designed for this challenge.
1. Example 1:
VALID - A custom macro to do a MULTI-THICKNESS SHELL command.
2. Example 2:
VALID – A custom macro to do a BODY MIRROR in 2 directions.
3. Example 3:
NOT VALID – A custom macro to construct the first 3 sketches of this particular challenge.
d. CUSTOM MASS CALCULATORS
i. Several CAD systems have custom macros/scripts to calculate the mass of a TooTallToby challenge.
ii. These custom tools calculate the mass of the model in both grams and lbs, and calculate the results for any of the 4 available material densities.
These types of macros/scripts are VALID, and CAN BE USED during these challenges.
Here are a few examples:
1. Onshape Custom Tool: https://forum.onshape.com/discussion/20134/tootalltoby-material-new-featurescript
2. Fusion360 TTT Materials Script:
https://github.com/rambros3d/CalculateMass-fusion360/releases/download/ttt/CalculateMass_ultimate.zip
e. TEMPLATES:
If you prefer, you CAN begin with nothing open, and then select a template, AFTER starting the clock.
i. NOTE: Generally, this will be slower, and all the above rules apply.
ii. The template CAN NOT have any of the above mentioned pre-created geometry.
5. MISCELLANEOUS
a. By submitting your video to the TooTallToby SPEEDMODELING Leaderboard you grant TooTallToby and team the right to use the video footage of your submission for any marketing/promotional purposes without limitation.
6. Any other questions
a. Ask on the discord
