DIM3D
A dimension or note on the 3D model: product manufacturing information (PMI) that is measured once the drawing is made 3D (folded, extruded, put together) and shown on the 3D page, in proof pictures and videos, in the 3D PDF and written to STEP as AP242 PMI. It stands on points of the flat drawing, so it follows them and the drawing's variables. To make one by clicking, measure on the 3D page and press Keep as Dimension (Dimensions in 3D).

| Kind | What it shows |
|---|---|
"LINEAR" |
The straight distance between the two points in 3D (with AXIS, only its part along that axis). |
"ANGLE" |
The angle at the corner between the lines to the other two points: a fold's angle, a slope. |
"RADIUS", "DIAMETER" |
A circle round the centre through the other point: R or Ø and its size. |
"NOTE" |
A note in a box, its leader pinned to the surface at the point: its text is the CAPTION. |
Each point is a point of the flat drawing, taken on the panel or solid it lies on: on a panel's outside face, on a solid's top there, unless a height says otherwise.
Settings
| Setting | Meaning |
|---|---|
Z=height |
The height of every point: above its panel's middle, on the inside (as a MATE's); on a solid, in its own frame (0 its underside as drawn). An expression. |
Z1=, Z2=, Z3= |
The height of the first, second or third point alone. |
DIST=distance |
How far the dimension line stands off its points (a note's leader length, an angle's arc radius). Left out: two and a half times the text height (a note: four). |
AXIS="X", "Y", "Z" |
Measure along that axis only: AXIS="Z" a height. |
PLANE= |
The plane it is drawn in: "FACE" the surface's at the first point; "X", "Y", "Z" (or "-X" …) square to that axis. Left out: the main plane through it turned most toward the usual front-right view, set off away from the model's middle. |
TOL=tolerance |
A ± tolerance, shown after the value and written to STEP. |
VIEW="name" |
The saved view it belongs to: the 3D PDF has a view of that name showing it, STEP a draughting model. |
The text settings are a 2D dimension's (Dimension settings): HEIGHT, ARROW,
GAP, EXTEND, DECIMALS, CAPTION (with <> for the value), KIND, FONT, BOLD, ITALIC, WIDTH. The id,
layer and any settings after them are the element settings. In the flat drawing it
is drawn as a thin line through its points marked 3D (a note: its text); it is never cut, folded or exported in 2D.
Examples
P0=[0,0]
P1=[100,0]
P2=[100,60]
DIM3D @20,"LINEAR",[P0,P1],0,DECIMALS=1
DIM3D @21,"LINEAR",[P0,P0],0,Z1=0,Z2=20,AXIS="Z"
DIM3D @22,"NOTE",[P2],0,CAPTION="Glue flap"
The first is the 100 along the edge from P0 to P1 as made; the second a height of 20 at P0; the third a note with its leader on the surface at P2.
