Sorry if this has been asked before. I'm trying to get some real-world measurements of props in Poser. I have several of the free ruler props but none have the same scaling. I also have an old prop called "two-meter" which is for measuing figure hight but I'm not sure if that is scaled correctly either. 

maybe I've overlooked something in the Poser ref manual?

Have you tried this?

Lately I just load a ball prop, scale it down to a manageable size, set my Poser unit measurements to feet, and translate the prop.  I guess there's been some long controversy about scaling accuracy in Poser, and possibly some may protest that Poser's internal value for inches and feet may be incorrect or incompatible with the scaling of some products or freebies.  I haven't noticed any particular trouble with the approach, however.  Although it does seem that most figures are just danged tall.  I think Antonia was about six feet, which is Julie Newmar kind of tall.  Umm.  :unsure:  I think I'm drifting a bit.  Umm.  :unsure:

thanks. that should do it. I remember his tutorials but forgot where they were. Book marked his page as well.

yeah, I think V4 is almost 6 feet tall as well. Not really real world sized. 

tall girls are nice IMVHO.  maybe these poser modellers also like 'em tall.

p.s. translate the prop and measure translation from prop origin (0,0,0) to new prop origin (0,y,0).

No, you haven't overlooked anything.

The short answer is that over the years, Poser has had 3 different scales:

The Poser 5/Daz Studio Scale - The one most people use. (V4 = 5' 10.4 inches)

The Dr Geep Scale - less used - most useful when building things, the math is easier (V4 = 6' 1.4")

The Poser 6 scale - The internally correct scale that no one actually uses.  (V4 = 6' 3.7")

There is a great website that gives a more detailed explaination, along with every figure height for each scale:

Review this page & pick your scale - I use the DrGeep scale, rescaled for the Poser 5/Daz Studio Scale

Two things that are going to make life simpler if you want the characters shorter:

1. Scaling and in particular single axis scaling now works right in poser. The Morph++ pack for Vicki also includes a morph to shorten the arms and legs.

2. The is a script coming to market in a few days that allows you to mix M4 or V4 with K4 and get unlimited character sizing options.

very interesting. Now I know why Ive had to strech out old chair props that looked like they were made for tiny people.

Here's a ruler if that helps.

Here's how I measure things in Poser:

I set Poser to meters and used a cube prop and moved it 100 units along the y-axis.

Then I scaled a second cube prop up until it was as large as the distance the first cube had moved.

This cube was now 1x1x1 meters or 100x100x100 cm.

I exported and re-imported it so it's scaling was now 100%.

If I want to measure anything, I simply scale that cube.

Scale it to 184% along the y-axis and it's 1.84 m tall.

Scale it to 200% along the x-axis and it's 2 meters wide.

That's PP-2012's internal scaling and each figure and each prop I use has been resized to match it's real world size using my meter-cube.

This way, everything fits to everything else and I never have to worry about mis-matched scaling. It is also much more accurate than simply scaling everything to "match V4".

Of course this makes V4, M4, V5 and M5 quite tall, but I normally don't use them and they are quite unrealistically proportioned anyway.

(And of course at least V4 and M4 can be easily re-scaled and saved to the library in a more realistic size. Genesis sadly get's broken if you try that)

If you are measuring against other objects, use the orthogonal cameras, as they do not exhibit perspective...

"If you are measuring against other objects, use the orthogonal cameras, as they do not exhibit perspective..."

That's not necessary if you build yourself a "metering cube".

You simply scale the cube to the dimensions you want, then scale the prop or figure until it's covered by the cube.

In this example, a full scale Lancaster Bomber was shrunken into a 1/72nd scale model of a Lancaster.

The original had a wingspan of 31.09 meters, so the model needs to have a span of 43.1 cm.

And the best thing is you can measure all three dimensions simultanously.
