Hi, this is so helpful! Thanks so much.
I was just wondering if you would be able to give a more exact figure to the "9.524" figure you've quoted.
I'm using this to export my architectural drawings in Axo to scale. a few more decimals would be fine but the more accurate the better. in the last drawing I exported to AutoCAD with this the measurements were nearly there, but 176mm out on just a height of 3500mm (before scaled). on a directly vertical line
Thanks again!
Luke

Luke...
Can you try a few options to see what works best - I established the ~9.524 mathematically.
If your 176mm in 3500mm is correct [and not a result of other factors] then the figure needs to be adjusted not by a few decimal places but either ~9.476104 or ~10.002924 depending which way the error seems to be more or less...

Lersince1991

Sure, thanks for the quick response.

its the same on every system and model isn't it? no need to change the factor every time, just need to tweak it slightly

Heres some data for you based on a cube 3500x3500x3500mm
(scale factor) = (45 degree line) & (90 degree line)

9.476104 = 3489.3444 & 3657.4247
9.5724 = 3489.3444 & 3675.9107
10.002924 = 3489.3444 & 3860.7576

Ideal is of course...

(x) = 3500 & 3500

Cheers,
Luke.

Got a final figure for you, pretty accurate but will update if I find the need to go more decimal places, for now I dont know how to see the exact figure from autocad.

basically the cal is.

3500mm (actual height) / 385.9629 (exported height from axo4545) = transform scale

Working between autocad and sketchup pro 8
should be the same for all though

Luke.

Lersince1991

sorry forgot to add the actual z scale factor = 9.068229097
this produces 3500.0001 in autocad
but the 45 degree angled lines aren't quite there with a dimension of 3489.3444mm instead of 3500. although they are at the correct angles (45 and 315 or... -45)

Luke Riggall

Lersince1991

and...
scale factor for the x and y sides (proportionate) is 1.003053754

can anyone confirm both of these?
if so could these be made into actions (scripts?) in order to prevent all this decimal typing lol.

Good stuff
Luke

TIG

So can we agree on a final vertical scaling factor, to export the perfect 2D Axo and I think about a script to do it...

Lersince1991

A script would be great.
heres the final values, I've done them to a bit more of an accuracy, accurate to more than 1mm for models under 100,000m so yeh pretty solid figures.

I would scale all axis to get them accurate,

blue (z) axis scale value = 9.068228873
red axis scale value = 1.003053768
green axis scale value = 1.003054401

see what script you can do, typing that in every time gets boring lol

Luke

TIG

Thanks... I'll cogitate over an automation...

Here's an update - v1.2 http://forums.sketchucation.com/viewtopic.php?p=252273#p252273
It now auto scales the whole model to distort it so that 3d axos will look right - using:
axo_scale
and undoes that scaling with:
axo_restore_scale
Use these tools with care!

Great plugin TIG!

A few suggestions/requests/bugs from a test I did with 2 cubes:

1.If you run axo4545 and then axo_scale - it cuts the top of the cubes. only if you run axo4545 again it works out for some reson...

2.Axo_restore_scale gives me the following error :
axo_restore_scale
Error: #<NameError: (eval):149: undefined local variable or method `axo_restore_scale' for main:Object>
(eval):149

3.Is it possible to show shadows correctly after you run axo_scale?

4.Is it possible to change the axis of alignment? the reason is because I need the shadows to be to the right , at normal usage I just orbit to bring the red axis down , but here I can't of course
for now I just do an horizontal flip on photoshop but just wondering if it's possible to setup easily

Thanks again for making such a great plugin

Sound like the notorious 'clipping issue' is your model very big, very small or far away from the origin ?
'axo_restore_scale' should be axo_scale_restore - my typo in the help section
The shadows will become distorted by the vertical scaling factor - if you want '45 degree' shadows I suppose we just need to find a long/lat/date/time where the 'scale' objects cast shadows that look as desired ? Set it as a Style that only retains those changes... If you play around with the shadow settings and advise what you'd like to do I can see if it's scriptable...
I can't see how to have other axes [easily] - rotating the exported image in PS or Gimp is probably the easiest solution...

Wow that was fast respone

1.Ok , It's happening only on rare occasions with v8 ( last time I tried it with v6 ) so it's really minor
2.Working great!
3.How do I set it as a Style? ( I'm new with sketchup so sorry if it's a dumb question , but I couldn't find it also in the help section.. )
4.Will do , Thanks

I've attached the example i'm working with
The image is flipped horizontally and thats what i need to accomplish eventually ( of course with the z factor correctly )

Thanks again for all the help

To save your shadow settings use a new Scene tab that retains the shadows as set in your Style.
Make a copy of the Style with those shadows set and nothing else.
Then you should be able to click the Shadows Scene tab and then nothing else changes except the shadows swap to your settings.
You can export a Style and re-import it into another model OR have it set as one of the styles in your normal template, so all new models get that style as one of the available ones...

Gutz

Maybe I'm doing something wrong , But it saves the "Shadow settings" ( time , date etc. ) and not the shadow itself
So I'm only getting the direction of the shadow and not the actual shadow from the unscaled model

Thanks

You can only save 'the shadows' as an exported image, the 'shadow-settings' are remembered with the style...

Gutz

Sorry but I don't understand how to do it
Can you make an example?

Gutz

Sorry for the bump
But I still can't figure out how to get this to work with shadows correctly shown..

I don't know how to get the shadows to look right either... that's up to you by adjusting location, north, date time etc.
Once you have that save a scene with the only thing fixed as the shadows [as explained].
Then later you can use that tab to reset shadows to those values again...

Gutz

I think we are not on the same page here , Lets make it a simple question :
Is it possible to show the model ( even just exporting an image it doesn't matter) with axo_scale , but with shadows shown correctly as if it wasn't scaled?

If so , can you please make an example?

Thanks in advance

No.
Shadows come from the geometry, if you've scaled it the shadows won't be the same.
You could make the axo, export an image with shadows then.
Switch off shadows.
Now Scale the axo and re-export an image.
Use an image editor like Gimp to overlay the scaled image over the [now incorrect] shadows???
I fail to see how how the 'wrong shadows' will look right on the scaled skp's image.
Can you explain why you need to do this?
If you want shadows then shading the scaled version will look right... IF you set the location/date/time appropriately...
