## Clip View

This function is used to hide parts of a model to facilitate texture correction in occluded areas.

There are two modes to clip view: **Plane Clip** and **Rectangle Clip**.

**Plane Clip:**

* **Clip from View:** Uses the screen window as the clipping plane.&#x20;

* **Quick Horizonal Clip:** Click a point on the model to use its elevation as the clipping plane.

Adjust the slider to change plane's position. All three planar methods are applicable.

Quick Button:

* **Enable Clip**: Display the clipping view.
* **Show Clip Plane**: Show or hide plane.
* **Invert Clipping**: Flip the direction to view.

## Measurement

**1) Coordinate Measurement**

Users can perform coordinate measurements by clicking any point on the model.

**2) Distance Measurement**

Users can click two points on the model to draw a line for distance measurement.

**3) Area Measurement**

Users can draw polygons for area measurement by clicking points on the model surface. Double-click to close the polygon.

## Import Annotation

Get3D ModelFun supports synchronized annotation with **Get3D Viewer**, allowing users to add **DVP** format annotations to both OSGB and OBJ views. This enables quick identification of problem areas and precise positioning.

* [Add labels in Get3D Viewer](/user-help-center/get3d-viewer/software-overview/analysis-menu.md#add-label) and export as \*.dvp file.

<figure><img src="/files/nkOpGUTdx63jv31TE9DR" alt=""><figcaption></figcaption></figure>

* Select annotation file(\*.dvp) path to import it. The windows will show the label information.

<figure><img src="/files/RoA7OrdpB0xCLqGjShFt" alt=""><figcaption></figcaption></figure>

* Double-click label, and the model will move to the label position. Right-click label, it will display label information.

* When importing a large number of labels, you can search to find it.
