# Dimension Primary Units

We are having an issue with Dimensioning and the Primary Units not maintaining the correct value. We use metric so the multiplier of 25.4 or .039370079 for Dim Scale Linear would be used in our Dimension Styles depending on if we are drawing in model space or annotating in paper space. We have created specific Dim Styles for Model and Paper space. Every so often some of us will us the Dim Style for paper space and a metric unit would be shown. When we go into the properties of that dimension and change the Dim Scale Linear to 1 it shows as a different dimension then it actually is. After looking at the correct dimenion, we noticed the Dim Scale Linear shows .9449 but gives the correct dimension.

Note: We are drawing in Metric a multiplier of 25.4, our dimensions are done in english. A scale factor of .039370079 is used to accomplish this.

There is a simple fix with Match Properties but it still doesn't answer why our dimension show up wrong with a different multiplier for Dim Scale Linear.

Anyone have any ideas?

is there a reason you are shying away from using one single Annotative Dimstyle for all your dimensioning needs in a file? You must also set up an Associative Text Style but it's way simpler than juggling two dimstyles like you are doing.

Whatever your answer, not posting a DWG that exhibits the problem is just going to prolong finding you a workable final solution: pony up a file.

Attached are four screen shots measuring a random geometry for an example...

36.jpg is showing our Dim Style showing English. Notice the primary Units Dim Scale Linear shows .9449 and in the Dim style it's a scale factor of.039370079 which gives us the correct length (with associative dimension on).
914.jpg is showing if we change Dim scale Linear to 1 to verify our metric dimension, it is showing the correct length but when going back into properties of this dimension it now shows -24. Instead of a 1 to 1 or 25.4 (with associative dimension on)
1 1_2.jpg is showing if we turn off associative dimension with our correct Dim Style. Properties is showing a Dim Scale Linear of -.0394
38 1_16.jpg is showing if we change Dim Scale Linear to 1 (expecting it to show either metric units 1 to 1) it gives us a length larger than the actual length.

I'm lost. I have no clue why our correct Dim Style would be showing some random multiplier in Dim Scale Linear when the scale factor in the Dim Style is setup correctly. Also why it would do those things when associative dimensioning is turned off.

I am a fan of annotative text but the company standards are set. Yes annotative text would solve this issue, but we draw everything in 3D and when presenting our drawings we would then have to turn off the layer in certain viewports to hide the dimensions.

Sorry, but without a DWG file the posted images don't show what settings are in play or how the two dimstyles differ.
