Keyword：Replace｜Update｜Mismatch｜Location change｜Coordinates > Similar question: > > \- Why does the brush plant produce an offset after updating/replacing the model? ## Solution: 1. **Import the model directly in D5** : After importing the model, click the "Sync Coordinates" immediately. Then, if you update the model, even the overall range (bounding box) of the model changes, the model will remain in place. 2. **Use D5 Workflow Plugin** : If the D5 converter is used in the sync workflow, there will be no displacement issues.

## The reason for the issue: The coordinates of the model that is imported directly into D5 is set to the default point A at the bottom center of the model. If the overall range(bounding box) of the model is changed after replacement, the position of the coordinate axis will be recalculated and changed to point B, which can cause displacement issues. By clicking the "Sync Coordinates" after selecting the model, the model will be restored to its absolute modeling coordinate position. {% hint style="info" %} **Note:** **If the imported model is a .d5a file with group structures**, please perform the ‘Sync Coordinates’ after the first import and after replacing the model, respectively.

{% endhint %} *** **e.g.** (As shown in the figure below) if you have three models, a square, a circle, and a rectangle, and the coordinate origin of the models is at point A (D5's coordinate axis is set to the bottom center of the model by default).

If we delete the rectangle, the coordinate origin of the model will change from point A to point B.

If we align the coordinate axis at this time, the models will move.

*** This is why the model stays in place even if the bounding box changes.
