Remove/Hide dashed lines

I downloaded the following model from the 3D Warehouse and it is filled with numerous dashed lines.

How can I remove or hide them?

Go, View and untick Hidden geometry.

View>Hidden Geometry should take care of it.

Thanks for the quick responses. That worked (see image below).
However, how can I keep or add an outline around the major forms?

For example, notice how the flower shapes have an outline.
