Using the ClipModel.mvba
ClipModel.mvba was written to cut 3D road models produced by InRoads and GEOPAK. In the past models were contiguous from beginning of the modeled corridor to the end of the modeled corridor. Applying schedule simulation was next to impossible because roads are built in stages and there are multiple stages going on at the same time. Once applied to the model the pieces of the model will allow schedule simulation to be applied.

The ClipModel.mvba works by copying graphics within a shape from reference files to the active master model. The graphics can be anything, including meshes. The shapes can be in a reference file. The only requirement is that you must create a selection set out of the shapes. The shapes define the clipping boundary to clip and copy the contents visible in the shape.
Creating the shapes:
Creating the shapes is left solely up to the user. They can be on any level or have any symbology. They must be closed “Shape” elements.
To create shape orthogonal to an alignment can be done by several different methods. The easiest way is to use the InRoads command Evaluation > Volumes > Triangle Volume by Station. Make sure you have the toggle on at the bottom of the dialog to create the shapes. You also must have one surface loaded besides Default. You set the interval and width left and right of the alignment. After running the command the shapes will be created. You can ignore and dismiss the volume report.
NOTE: If you use the same interval as your template drops or the shape side falls on a template drop the results may not be correct due to tolerance issues. To solve this problem select all your shapes and shift them by 0.001 in either east,north or both. (Use the MicroStation Move command and the dl= key in (e.g. dl=0.001,0.001,0))
