AutoCad :: Dimension Not Show To Annoscale Size

Why are annotative dimension always placed in model space to the created height regardless of the annotation scale I use. using annotation 1:1 or 1:10 or 1:50 my dimension is always inserted to the dimstyle hight of 3.5mm (about 1/8") and not 3.5 x annoscale example 10 = 35mm.

When dimensions are placed using an anno scale of 1:1 and than change the anno scale to 1:10 the dimensions and dim arrows ect are scaled to the correct size 10x value preset in the dimsyle. My text style is non associative and set to 0.0 height.

The only way i can place dimensions to the preferred height is linked to the anno scale is by setting the text style height 3.5 (about 1/8"). but the problem here is that the dim text height will be displayed to selected annotation scale of 1:10 but the dim arrows etx are not to size. I know that setting the text style hight is not the correct way and see why.

All my dimension styles are annotative and and have the ANNOAUTOSCALE set to 1. I have also tried by presetting the object anno scale to the preferred annotations.
