Surveyor 2.0 is still incomplete. Bulk Asset Update/Replace is one of those Surveyor Classic tools that have yet to be implemented in S20. However, there is a limited object replacement option that can be found in the Context Menu of most/all selected objects.
Replace Object with Selected Asset - the
selected (highlighted) object will be replaced with the asset currently selected in the
Assets Palette. If no object has been selected in the
Assets Palette or it is the wrong type (e.g. a scenery spline instead of a mesh object) then this option will be greyed out.
For example: You can select multiple track splines (
Shift + Left Click to select individual track segments or
Double Left Click to select them all up to the next junction), open the
Context Menu of one of the spline objects and, provided a track spline asset has been selected in the
Asset Palette, click the
Replace Object with Selected Asset menu option. All the selected track object segments will be replaced with the selected asset.
