When working in a general arrangement drawing, you might notice that some changes are needed in the model. For example, you might need to correct object geometries, modify object properties, and add missing parts. While having the general arrangement drawing open, you can open a suitable model view or create a new model view, and then edit the model without closing the drawing. The changes you make in the model are immediately visible in the drawing.

When you have a general arrangement drawing open:

1. Open a model view for editing.

   You can select the model view in the Model view side pane, from the list of views on the Window tab on the ribbon, or from the model if you have many model views open.

2. If needed, on the ribbon, click the Window tab and select either Tile horizontally or Tile vertically to view both the drawing and the model at the same time.

3. In the drawing, select the objects that you want to modify.

   The objects that you select in the drawing are highlighted in the model. You can select one object, multiple objects, or you can use area selection.

4. Switch to the model by clicking by the middle mouse button in the model view.

   Clicking the model view with the middle mouse button will keep the objects selected. When you have switched to the model, the modeling ribbon, property pane, and toolbars become available.

5. Edit the model as needed.

   The changes are immediately visible in the drawing. When you select objects in the model, the objects are highlighted in the drawing.

6. Switch back to the drawing by clicking the middle mouse button in the drawing.

   Clicking the drawing view with the middle mouse button will keep the objects selected. When you have switched to the drawing, the drawing ribbon, property pane, and toolbars become available.

1. In the drawing, select a view.

2. Right-click and select Create model view for selected view.

   You can also open the contextual toolbar and click the Create model view for selected viewbutton.

   A temporary view is created. The temporary model view has ( ) parentheses in the name.

3. To keep the view, rename it or just remove the parentheses from the view name.

   You can easily rename the view in the Model views side pane. If you do not rename the temporary view, it is removed when you close it.

If you want to prevent model editing while having a general arrangement drawing open, you can set the XS_ENABLE_MODEL_EDITING_IN_GA advanced option to FALSE. The default value of the advanced option is TRUE.
