Mixing millimetres and centimetres

David Waight

I have noticed in the latest V20 Windows that when working in millimetres, if I go over a 1,000 millimetres with an entity it reports the length in centimetres!

If I create a viewport that is longer than a 1,000 millimetres but shorter in height than a 1,000 millimetres it shows it as for example 110.00 cm by 950.00 mm!

Is this some new kind of measuring convention or is my system playing up?

Thought I would put it out there before sending an SR.

Thanks in advance

I find this very distracting.
Like when you have a cm INSUNITS file and draw and your
DYNDIMS switch to meters. But when you input a meter value
it will recognize input as centimeter (=INSUNITS)

You can deactivate units for DYNDIMS,
but if you use them, it seems that Bricscad tries to adapt units
according to value, by any of the units activated in you
LENGTHUNITS, AREAUNITS and VOLUMEUNITS.
I think the only workaround is to throw all unwanted units out
of that list.
Which is bad if you need to work in another project in different units ?
Basically it should be a File Setting, not a Program Setting (?)
so I would need a File Template Setup and adapt all imported files ?

So it is good when you file your SR,
at least someone will explain how it is meant to work.

The PROPUNITS system variable controls which value fields (lengths, areas and/or volumes) are automatically formatted (= indicate a unit). Which units are available is defined by the LENTHUNITS, AREAUNITS and VOLUMEUNITS properties.
When you type a value without specifying a unit, the value is expressed in drawing units (= according to the INSUNITS setting. You can use any valid unit in entry fields. In a mm drawing typing 3m is equal to 3000. How the length displays depends on the LENGTHUNITS setting.

Hi Louis,

Thanks for the info. I have got it back to how I had it in V19 :-)

Many thanks
