Converting Point Data to Areas

I have a shp file of pt data that defines a tree height/canopy area per pt. Is there a good way in GM to take each pt and create a circle or square polygon sized based on canopy sq area and also having the height mapped to the new polygon.

Do you have the canopy area as an attribute value in your shapefile? If so, it sounds like you would like to 'auto create' polygons from selected points - using an (canopy) area attribute value to define the polygon, and using the selected points as centroids for the polygons. Please let me know if this is what you are looking for.
We have ways to add height or elevation to existing features - do you have a DEM loaded? There is an option on the right-click menu under Analysis/Measurement to Apply Elevations from terrain Layers to Selected features.

Each ring should also get any other attributes from the points automatically, including the height, so you should have 3D areas at the specified height and radius just like that!

I have a question that relates to this - I am trying to do something fairly similar, but I want to keep both the points and areas, and update attributes of both over time.
Is there any way to create a hybrid point/area symbol, that would work so that if I changed an attribute of the point it would automatically change the same attribute of the linked area? Then I won't have to remember to go into each separately, and duplicate the action of updating the attribute?
If I have to duplicate the attribute update for each of identical point and area symbols, it will take longer each time, and there is more potential for error!
Otherwise I could delete all the areas, and re-generate the areas after updating the points each time, but I think it will be simpler if I can create an area at the same time as creating a new point, and link the attributes of the areas to the points so that the areas just auto-update?
Thanks,
Amanda
