scaling a point style

[Anonymous]

I need some help with point styles

when the surveyor's pick up an existing tree this is the code as shown in the field book.   The first code shows that the point is a deciduous tree with a diameter of 75mm.  The second line shows the beginning and end of the dripline of the tree from the tree to the edge of the dripline of the tree
ZD VD 10282 125.361190 9653.739 55.348 "DEC 075"
BEG DRIPL1
ZD VD 10283 125.361188 9653.743 55.334 "DRIPL1"
ZD VD 10284 125.354321 9653.139 55.249 "DRIPL1"
END

The point style for DEC has a marker (Autocad Block) called  called nf_tree_decid which has a circle where the trunk is and a pline around it where the dripline should be

this is the label style we created to include the diameter of the tree
<[Tree_Diameter(Umm|P0|RN|AP|GC|UN|Sn|OF)]>%%c

and there is a User-Defined Property Classification to allow you to enter the Tree Diamter,species

to make a long story short.  We would like to be able to stretch the block of the tree to match the dripline and then  change the circle (trunk) to match the diameter that was picked up in the field.  With our currect setup we need to go in the properties and change the x-y scale in the geometry section to scale up the tree  block but this also scales up the diamter at the same time

any help would be appreciated

There is not a way to do what you are asking with a single point style. 

An option would be to shoot the tree with the code as follows:(assuming you have 2010 or 2011)

"DEC 075 CIR25.0"

This will allow you to insert a tree trunk point and scale it up using the $1 parameter in your description key.  the remaining portion of the code will draw a circle figure at the specified radius.  Check the help file for other uses for the cir field book command such as shooting two or three points.

Another option is to write a program that will read the values and insert a dynamic block at each point and scale the components according to the field codes.

We have gotten away from showing the drip lines on our surveys since we have an arborist on staff that will create a report for this information.  the survey is for locative purposes only.
