1. in model space do _line 0,0 100,0
2. in paper space set viewport scale to 0.05 (1/20=0.05)
3. measure length of 1 step line in pspace, it must be 5.0 (100/20=5)
Ok I did just as you said and the line measures just as you said
100' in model and 5' in paper.
But why can't I get my zoom .6xp to set my veiw port at 0.6
( 1" ft ) It is my understanding that everything in paper is in
inches therefore since there are 12" in a foot I"m multiplying 12
times 1/20 or 0.05*12=0.6 since we draw everything in feet being
the smallest unit in model
How are you measuring lines in modelspace?
Modelspace should always be drawn at a scale of 1:1 ie fullscale.
If your natural dimensions are inches then a line drawn 20 units long would
be equivalent to 20 inches.
In paperspace you now set your true scale ie 1" = 20ft. Since your
modelspace is in inches the paperspace scale should only be 1/20 or 0.5 NOT
1/20*12 = 0.6. The later would only apply if your are drawing lines in
modelspace at a scale as well. This is not good practice. Draw everything in
modelspace at 1:1 and paperspace scaling will then be the true scale you
require (in this case 1/20 = 0.5). Don't draw in modelspace at scale and
then go to paperspace and scale again - way too confusing.
Hope this helps.
My units are feet not inches, we do civil engineering not architectural.
Wrong, my model space units are feet (and decimals of the unit feet)
Nope don't do this.
Not really, I feel like I missing some command sequence in the zoom ...xp
or something because I can't seem to get my viewport in paper to be what
I calculate it to be. Maybe I don't know how yet to create a viewport properly.
==========================> try this:
That's it ! I was forgetting the old algebra rule of PEMDAS or
multiplication before division.
If I take 1/20 =.05 then times 12= .06 I violate the rule, how mathematically
stupid of me.
But if I obey the rule (like you pointed out) I get 1/(20*12)= 0.00416666
Thank you for snapping me out of my loop.
Now I can concentrate on honing my viewport skills
Issue was resolved. 1" '-0" is 1/240 not 12/20. Not all scales are
available as predefined from the properties dialog box. for those that
use different scales, being able to calculate the correct scale is very
