The jet drive starter takes …, each {name, expression}
The magnet's pocket could not be checked.
The mate needs a finite [x,y,z] offset, a finite axis rotation, and valid interface frames.
The mate's ports are gone or its offset is not finite
The mechanism can't be posed:
The module transaction would leave an invalid dependency closure; no changes applied
The new size would not leave two valid printable enclosure Bodies.
The pivot's features miss …. Put the pivot at that Body's end.
The plan has no part to build: give its roles, each started by a feature of op new
The pocket misses Body …. Put the magnet's face on that Body's surface.
The ports' frames or offset_mm/angle_deg are not finite; nothing changed
The prepared Part cannot be reopened. The original Part has not changed.
The replacement cannot retain the existing source mate intent

The resized enclosure's insert pockets did not pass their geometry checks.
The resized lid would collide with its housing.
The saved … snapshot has no usable … pitch surface.

This Part changed while print groups were open. Reopen Print groups and try again
This Part has later edits; restoring the Ask checkpoint would discard them
This Part was saved by a newer MakerSketch. Update the app to open it.
This assembly has no saved enclosure recipe. Edit its ordinary features instead.
This assembly participates in a mechanism solver. Reusable-module capture does not yet freeze mechanism joints; detach the mechanism explicitly or keep this assembly in its project
This construction participates in a saved mechanism. Its independent joint coordinates cannot be regenerated by this plan; revise the mechanism with native CAD before changing the construction.
This document already has a mechanism. Create the servo gripper in a document without one.
This is a pinned reusable module. Unpack it to an ordinary assembly before ungrouping, so its frozen instance association is not orphaned
This isn't a MakerSketch Part
This isn't a MakerSketch Part: part.json is missing

… has no letters the sketch font can draw: use plain letters, digits and punctuation
…: …
along puts the part's port that far along to_port's axis: give it with to_port, instead of offset_mm and to_point
along …: …. Use mm or the plan's parameters
axes is a list of the train's parallel axis ports or datums, such as ["input_axis", "idler_axis", "output_axis"]
axis needs point [x,y] and a non-zero direction [x,y] in the sketch's own 2D (a 3D point or direction is projected into the sketch plane)
construction starter takes starter and parameters only: [{name, expression}] for …
construction … doesn't take …; it takes …
degrees must be above 0 and at most 360
edges must be sides, top, base or all
feature must be one of …

no … on this object
not a number
obstacles is a list of Body names or placed-part instance ids
op must be new, add or cut

… has no port …. Its ports:
… has no sections; give its loft at least two
… is a plane datum with no direction, so there is no axis to fit around. Give it the direction its shaft runs (construction {action: draft, instance_id, expected_revision, datums: [{name: …, position, direction: [x, y, z]}]}), then fit around again
