You already have the container. What you need is a base designed around your measurements—and a CAD model you can check and keep working on.
For this Nora3D example, the brief was specific: a 21.5 mm opening at the bottom of the pocket, a 4 mm base, and a 12 mm support above it. Codex passed those dimensions into a parameterized Nora3D modeling workflow to create a solid container-base model with its construction history intact.
The value starts there: the measurements become part of a design you can inspect.
Give each measurement a place
“Make the opening 21.5 mm” leaves an important question: measured where?
This base has a tapered pocket. The requested 21.5 mm dimension belongs at the bottom of that pocket, where it meets the top of the base. Naming that location gives the modeling task a precise target.
The two height measurements need the same clarity. The base is 4 mm thick. The support rises another 12 mm from its top, putting the upper rim 16 mm above the underside of the base.
| What you specify | Where it applies | Checked result |
|---|---|---|
| 21.5 mm opening | Bottom of the central pocket | 10.75 mm radius |
| 4 mm base thickness | Underside to top of the base | Z = 0 to Z = 4 mm |
| 12 mm support height | Top of the base to upper rim | Z = 4 to Z = 16 mm |
This is a useful way to brief any dimensioned part: give the number, its location, and the surface it is measured from. That makes the result easier to check.
See how the part comes together
The model combines a broad circular base with a tapered support and an open central pocket. Nora3D retains the seven construction features in the document's history, so you can follow how those shapes become one solid.
The history gives the finished shape context. You can see how the base, support and pocket relate to one another, then inspect the dimensions in the resulting CAD document.
Keep a model you can return to
After construction, the document was saved and reopened. Geometry checks confirmed the 21.5 mm bottom opening, the 4 mm base thickness and the upper rim at 16 mm. The result was one valid, closed solid.
Playing its construction history also returned the document to the same final geometry and saved revision. The finished part and its history remained together.
For a maker, that means there is a defined starting point for the next design decision. You can return to the saved model, inspect what was built, and plan the next change from dimensions you already understand.
For a related example of revising connected parts, see how a PCB carrier gained more headroom and a wider cable opening while retaining its mounting base.
Start with the part you need
Bring the measurements that matter to your project. State where the opening is measured, where the height starts, and what the finished part needs to do.
In this case, three dimensions became a saved solid model with a visible construction history. The next step starts with something concrete: a part you can inspect and continue designing.
