How to fix Components Scale Dynamic Sketchup

Dynamic Component often crashes scale when you copy Dynamic object. The cause of the Scale error when copying a Dynamic object is that the child objects still mistakenly recognize the parameters of the original parent object. Especially if you use Groups located in Dynamic Component, this error is almost certain to happen. This is the default bug of the Sketchup software, and it still reproduces on the current SketchUp 2026 line.

The deeper reason is worth knowing, because it tells you how to avoid the bug in the first place. Groups do not carry their own definition the way Components do, so when you copy a Dynamic Component that contains nested Groups, the copied Groups stay attribute-linked to the original — the values turn red (broken) in the Component Options dialog, and renaming the group will not sever that link. The practical workaround when authoring is to convert every nested Group into a Component before adding formulas; a Component instance gets its own clean copy of the attributes and survives copy + scale.

There is a second, lesser-known trigger behind the “crash on scale”. SketchUp only recomputes a Dynamic Component’s formulas when YOU scale it with the Scale tool — that user action fires the redraw. A copy made with Move + Ctrl (or pasted from the clipboard) is never asked to recalculate, so its children keep the parent’s old, hard-coded dimensions until something forces a redraw. That is exactly why simply right-clicking and choosing Scale Definition, or nudging a value in Component Options, sometimes “magically” repairs a copy — you are manually triggering the recalc that the copy never received.

Fix Dynamic Scale is tool inside 3dshouse Dynamic Plugin to fix this bug. It forces the selected instance to re-evaluate its formulas and rewrite its child geometry to the correct size, so you do not have to explode-and-rebuild or restart SketchUp to clear the linked attributes.

Fix Dynamic Scale Tool Usage:

1. Step 1: Select copied Object
2. Step 2: Scale to crashes.
3. Click icons

Tip: select all the bad copies at once before clicking the tool — fixing them in a single pass keeps every instance consistent and avoids re-linking when you copy a still-broken one again.
