To specify an isometric start point in the 3D model

Without specifying a start point, the beginning of the line can be arbitrary. You can place a start point in the 3D model to specify a start point.

For example, the valve assembly displays on sheet 3, but you want it to display on sheet 1.

1. On the ribbon, click Isos tabIso Annotations panelStart Point.
2. Specify a point near the start of the line. The start point displays in the 3D model.
   
3. In the drawing area, specify an insertion point on the center line of pipe or a fitting. For example, node snap to a valve port.

   If the marker is obstructed, switch to wireframe view.

4. 
   If you create new isometric drawings, the valve assembly now displays on sheet one.

Note: You can save the isometric start point in the 3D model at the same time you save split points. Placing a start point manually is required only if the default start point is not correct.
