Fix rebuild errors and red sketches

Caddie sees every rebuild error, warning and sketch problem in the open model. Ask in any words and it tells you what's wrong, why, and the quickest fix.

Conversations on this page are word for word from Caddie's test runs on sample models.

Just ask

You don't need to name the feature. Caddie reads the errors first, so even "help" gets a specific answer.

Caddie

Fillet1 is failing because its 12 mm radius is too large for the selected geometry. Your base is only 3 mm thick; the guide walks you through trying a 1 mm radius and checking the preview.

What Caddie can see

Rebuild errors and warnings on every feature, with the reason SolidWorks gives, such as a fillet radius that's too big or a missing reference.
Each sketch's status (under, fully or over-defined), its relations, and which ones are over-defining it.
Dangling relations and dimensions left behind when an edge or face they used has gone.
Parent and child features, so it can trace a failure back to the edit that caused it.
Mate errors in assemblies.

Three ways to fix it

Let Caddie fix it. When the fix is clear, such as a conflicting relation or a radius that's too big, Caddie shows the exact change. Click Do it. Most changes can be undone.
Fix it yourself with a guide. Say "show me" and Caddie highlights each step on screen. Good when you want to learn the fix.
Just understand it. Ask "why did this happen?" and Caddie explains the cause, so it doesn't happen next time.

Caddie asks to delete the Vertical relation in Sketch2, warning that deleting a relation can't be undone, with Do it and Not now buttons. — Asked “sketch 2 red why”: Caddie asks first, then says what it did and why the sketch was red.

After Do it: Deleted a Vertical relation from Sketch2, and Caddie explains why the sketch was over-defined. — Asked “sketch 2 red why”: Caddie asks first, then says what it did and why the sketch was red.

Live notices

Caddie keeps an eye on the model while you work. When a feature gets a new rebuild error, or a sketch becomes over-defined or under-defined, a short notice appears in the chat with a Fix it button. The badge at the top of the panel shows how many issues the model has; click it and Caddie fixes what it can.

Common problems

What you see	Usual cause	What Caddie does
Fillet or chamfer fails	The size is too big for the edges or the wall	Compares it with the geometry, suggests a size that should fit, and can change it
Red or yellow sketch (over-defined)	Relations or dimensions fighting each other	Finds the conflicting relation and proposes deleting it
Blue sketch (under-defined)	Missing dimensions or relations	Explains what can still move and how to pin it down
Dangling relation or dimension	The edge or face it referenced was deleted or changed	Names the dangling item and guides you to re-attach it
A feature fails after an edit further up	A lost reference, or a size now out of range	Traces parents and children to the edit that caused it

When Caddie can't make the fix

Some fixes aren't changes Caddie can make yet, such as adding a sketch relation, re-attaching a lost reference or editing a mate. Caddie says so and walks you through doing it by hand, with each step highlighted.
