Diameter symbol when dimensioning diameter

We are using solid designer 7.02 and annotator. When I choose the dimension option diameter I would expect it to automatically add the diameter symbol. This is not the case. Every time I dimension a diameter I have to go into prefix and choose the symbol. Can the diameter symbol be the default when selecting DIA Dimension option when the system is started?

Yes, for example this is done, when using the dimension standard "ANSI". When defining your own dimension setting, you can edit the field in the *.dms file, you have saved (DOCU::DIAMETER-TYPE :ANSI) (recommended) or you can set it with
(setf (dimtype-default-setting-diameter-type *default-dimtype-settings*) :ANSI)
and then save it to your *.dms file. In the am_customize, you'll have to add lines for loading your settings and set the right one:
(am_load_dim_table "/mnts/fw6/users/kahlem/yours.dms")
(AM_DIM_SET_STYLE :dim_name "YOURS")
Hope that help's

Sorry, there one mistake above: should be:
(setf (docu::dimtype-default-setting-diameter-type docu::*default-dimtype-settings*) :ANSI)
