CAD Constraints First Sketch
Use constraints and dimensions to make a sketch editable instead of fragile.
Topic goal to ladder route
Know the destination, then climb the route.
A topic is the maker goal. A ladder is the route from what you understand now to one visible proof you can build, sketch, test, or explain. This one ties back to Build an Obsidian Project Notebook.
Create a simple sketch that survives later changes.
Read the short lesson, watch one source tutorial, sketch the idea, check the math, then practice.
Create a small practice case for cad constraints first sketch and write what each step proves before moving to the next one.
Ladder steps
Each step should prove one idea before the project asks for the next one.
Name the part purposeLearn to name the part purpose as one discrete move in the project path. You can explain or demonstrate: name the part purpose.
Anchor one referenceLearn to anchor one reference as one discrete move in the project path. You can explain or demonstrate: anchor one reference.
Apply geometric constraintsLearn to apply geometric constraints as one discrete move in the project path. You can explain or demonstrate: apply geometric constraints.
Add driving dimensionsLearn to add driving dimensions as one discrete move in the project path. You can explain or demonstrate: add driving dimensions.
Examples to inspect
Use examples to read signals, not as blind recipes.
Practice horizontal constraint
Project signal
Horizontal constraint
Expected signal: A visible result you can compare before moving on
Practice coincident constraint
Project signal
Coincident constraint
Expected signal: A visible result you can compare before moving on
Practice one driving width dimension
Project signal
One driving width dimension
Expected signal: A visible result you can compare before moving on
Common traps
- Fully dimensioning random geometry.
- Using tiny line offsets instead of constraints.
- Drawing final detail before the main shape is stable.
Practice task

- Pick one related lesson and do the practice task.
Practice path
- Near-Copy Rebuild: Recreate one example, decision path, or worked explanation from CAD Constraints First Sketch. Keep most givens the same, then apply, explain, and check while naming each cue you used. Use the lesson's example block when it helps.
- One-Change Transfer: Change exactly one condition, number, input, symptom, material, or constraint from the near-copy case. Then apply, explain, and check again and explain what changed.
- Mixed Review Set: Interleave this topic with one prerequisite or adjacent idea. Write three short prompts: one recall, one application, and one comparison.
- Find And Fix The Error: Invent a plausible wrong answer, unsafe step, invalid assumption, or bad classification. Mark the first point where it goes wrong, then correct it using the lesson's check.

What does the 'Anchor one reference' step prove?
Learn to anchor one reference as one discrete move in the project path. Check: You can explain or demonstrate: anchor one reference.
What does the 'Apply geometric constraints' step prove?

Text lesson and video notes
This page works as a text lesson first. If you later watch a matching tutorial, use the notes pattern here to capture the build decision, timestamps, warnings, and the next practical task instead of saving a raw link.
Read the text lesson
Use the steps, examples, traps, and practice task on this page to understand the next move in a maker project.
Attach a video note
Save useful workshop or tutorial videos into an Obsidian note with timestamps, source links, and what each segment proves. The site does not need the video to be useful.
Review and practice
Download the cards, then finish the practice task before adding more links to your project notebook.
Source video for this ladder
Use the video as source material for notes, cards, and practice. The written ladder still works without playback.
Use the source as a companion, not as a replacement for the written ladder.
