dimensioning in paper space

Hi folks,

Is there any principle in applying dimension to paper space architectural drawings especially on a3 paper scaled 1:50; 1:100 and 1:75? The original drawings were drawn in 1:1 in model space.

Also, I will be very thankful if someone know the principle for vertical dimensioning or levelling say level +000, +3000 etc. to elevation drawings???

Thank you in advance,

Nicolas.

Dimensioning in paper space is no problem; we do it all the time. Just remember to have your OSnaps running, pick a suitable text height (Dim Style) and have a go at it. You are familiar with the use of viewports are you not?

i wont recommend dimensioning at paper space, , there is a possibility that the dim text will change value as per scale to paper dimensions, caused by dimension origins, ,

as for text height, , make a text style with a height of 0.00 , , it tends to scale itself according to what scale you have in a single dimension style, ,

for example:

romans, height 0.00

then make several dimension styles

for example:

scale 1:50

for model space this is the format if you are going to use a 1:50 scale>>

Dimstyle>modify>Fit tab

at "Use overall scale of" put 50 (if you intend to make a 1:50)

Dimstyle>modify>primary units tab

at "Scale Factor" put 1

Dimstyle>modify>text

use the text style u made, and put your desired height (in a 1:1 scale)

for example you want a 3mm high text, , you put a value of 3, it will automatically scale itself and the output will be 3mm..

now for paper space this is the format,

Dimstyle>modify>Fit tab

at "Use overall scale of" put 1

Dimstyle>modify>primary units tab

at "Scale Factor" put 50 (if you intend to make a 1:50)

Dimstyle>modify>text

use the text style u made, and put your desired height (in a 1:1 scale)

for example you want a 3mm high text, , you put a value of 3, it will automatically scale itself and the output will be 3mm..

take note:

you must scale your viewports, , example 1:50

zoom>scale

type this> 1/50xp

its easier using dimensions at paper space but it is much safer using dimensions at model space

^__^ goodluck

"i wont recommend dimensioning at paper space, , there is a possibility that the dim text will change value as per scale to paper dimensions, caused by dimension origins,"

Yes that is a possibility if you do not know what you're doing or can't make up your mind on what scale you're going to use. Knowing what you're doing and following good drafting practices will negate this.

Thank you very much. I will work on the proposed advices and let you know afterward how things went.

Best Regards,

Nicolas.

Create all your viewports and set their scale before doing any dimensioning. This will help you avoid potential problems down the road. Make sure Annotative is enabled in Dimension Style Manager. Click on the FIT tab, look to the right hand side, where it says "Scale for dimension features".

Actually I use to draw my plan in model space and then use trial and error to designate a text height for the different annotation and dimensions.

The dimensions are ok in model space, even in paper space. But then after using a page setup with 1:1 scale for viewport, I have more difficulties in designating the text height and dimension height. I have to reduce everything. In model space, a text height of 100-200 mm. suffice but in paper space, I have to do more trial and errors and have a negative impact on my drawing time. Worst with linetypes, patterns and so forth.

Hence centre line that are centre line in model space look continuous in paper space and vice versa. I usually find my way out but the time consumed with all this could have been used elsewhere and to more efficient goals.

Thank you in advance.

The objects in model space, have they been drawn full size or have they been "scaled"?

Re: linetypes and scaling.

Sounds like you're having a problem with the settings for MSLTSCALE, LTSCALE and/or PSLTSCALE.

In Model Space, the drawing are set in 1:1. I then go to paper space, set up the page to A3 and there also 1:1 scale. Then using different named views that I insert on the different paper spaces (plan, rhs elevation, section a-a, section b-b, etc) with the help of markers that I have draw with the first paper space. I then right click on the border and properties scale is changed and the drawing is locked.

And all your text and dimensioning are back in model space? If so, I'm assuming they are not annotative, right?

How do you mean safer? I think the dim text value change you are talking about (if i understand you correctly) is controlled by the DIMASSOC system variable:

Controls the associativity of dimension objects.

• 0 Creates no association between the various elements of the dimension. The lines, arcs, arrowheads, and text of a dimension are drawn as separate objects.
  
• 1 Creates a non-associative dimension object. The elements are formed into a single object. If the definition point on the object moves, the dimension value is updated.
  
• 2 Creates an associative dimension object. The elements are formed into a single object, and one or more definition points of the dimension are coupled with association points on geometric objects. If the association point on the geometric object moves, the location. orientation and value of the dimension is updated.

I assume you would use a dimension style with a scale factor, to represent scaled paperspace values. If you are dimensioning in paperspace and DIMASSOC is set to 2 and you select both dimension points from modelspace that scale factor is applied to the modelspace distance and displayed in your dimension value.

My recommendation is to devise paperspace dimension styles for each drawing scale you use. The text height should be constant throughout the styles to have a consistant look from printed drawing to printed drawing. DIMASSOC should be set to 1, and all viewports locked after the scale is set.
