# Transformation

## Scale Multiplier

Adjust the size of the model. A value of 100% corresponds to its original size.

{% hint style="info" %}
Some FBX files are loaded with a scale multiplier different than 100%. This is because the file contains information that it should be scaled up or down.
{% endhint %}

## Units Conversion

Select the measurement unit used in the modeling application that the model is coming from. In this way, the exact model's scale will be preserved in SketchUp.

SketchUp uses inches internally (this cannot be changed). So if you choose "cm", for instance, the conversion will be from inches to cm, hence the model will be scaled down by a factor of 0.3937 (1/2.54).

## Up Axis

Select an axis to be used as the up direction of the model, so that it is correctly oriented in SketchUp.

This is particularly useful if the modeling application that the model is coming from uses a different coordinate system.

## Origin

This moves the origin of the model (its pivot point). This is especially useful when the geometry has been modeled far from the scene's origin.

{% hint style="success" %}
***Bottom Center*** is very useful when converting plants or pieces of furniture.
{% endhint %}

## Soften Coplanar Edges

This softens edges between coplanar faces, [just like in SketchUp](https://help.sketchup.com/en/sketchup/softening-smoothing-and-hiding-geometry#soft-smooth). This setting is enabled by default.

## Smooth angle

When set to a value higher than 0, edges connecting faces with an angle higher than this will be smoothed. This is identical to the same function in SketchUp.

{% hint style="warning" %}
**Known issue:** the preview currently displays all the model's edges, even smoothed one. However, they will be correctly exported to the SketchUp file.
{% endhint %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://help.transmutr.com/manual/geometry-tab/transformation.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
