Issue
You want to use M-Color to color your plants.
Solution
Rather than M-Color, we recommend using our Color Render tool.
Our clients that use M-Color have to edit the plant blocks to create an outer boundary – either a circle or a polyline, on a non-plot layer.
We've spent a great deal of energy creating Color Render. Give this tool a try. It may prevent the need for a separate M-Color license.
