We have had a few questions about rounding dimensions to the nearest 5mm. This is not currently available via the Dimension Styles dialog but there is a method using a key-in that can modify an existing dimension style. You can test this in any design file without affecting standards then copy the modified dimension style to your standards dgnlib.
[please note the initial part of the command line is calculat, no 'e' at the end! DOS 8 character file naming lives on.]
In this illustration the lower dimension string has the rounding applied.
You can also use the command string as a temporary override without changing or creating any library styles, in which case updating the style from the library would reset it to the company standard, removing the rounding setting.
Also note that if a dimension with rounding exists you could also use the match text attributes tool to pick up the rounding setting.
'mdl load calculat' starts C:\Program Files (x86)\Bentley\AECOsimBuildingDesigner V8i Ss5\AECOsimBuildingDesigner\mdlsys\asneeded\calculat.ma
In this instance it is used to access an mdl command via the mdlDimStyle api. If you want to find out more about that topic area you can:
Search MicroStation help for the string "Calculator/Preprocessor" for guidance on the more general functions available from calculate.ma.
Thanks for pointing this out. I'll look into this. Looks like calculat.mdl is no longer delivered.
With CONNECT, this doesn't work: Calculator: "mdlDimStyle_setDoubleProp" is not a function. That is, the MDL function mdlDimStyle_setDoubleProp is not available in MicroStation CONNECT.
