Does “axo+iso.rb” works for Sketchup 2018, without distorcing the models into the file?

I found it from http://sketchucation.com/forums/viewtopic.php?t=29018#p252273

Thanks!

I don’t know what the word ‘distorcing the models into the file’ means but did you try the plugin? It works for me.


#3

it´s something like Axonometric Projection Eneroth Plugin does…

The “axo+iso.rb” seems did not work to me…


#4

How did you install it? I’m guessing not correctly. This is what I see when I run it.


#5

So…

Am I wrong?


#6

Yes. From your screen shot you haven’t actually installed it. Things have changed since that was written but when you click on the Download link, you will get a file called axo_iso_v1.2.rbz. Leave that in the Downloads folder. In SketchUp, go to Window>Extension Manager and click on Install Extension. Then navigate to where you saved the RBZ file. Select it and click Open. After that it should be installed.

Of course! How could I be so dumb?!

Thank you very much!!!

Now it worked!!!


#8

To this day I have not found a plugin that does like the axonometric perspective of the image … Do you know any?

The “axo + iso” does not seem to do as in the image above …


#9

Not quite sure of what you need but,
Have you tried Camera/Parallel Projection and Camera/Standard Views/Iso


#10

Yes. The point is, I think the axonometric perspective better shows the interior of the rooms, as well as providing a better effect than the parallel projection in the representations. :grinning:

From looking at your image above you’ll need a larger angle, looking down even more than SketchUp’s isometric view. But you can set up any angle to target that you like.
See attached image that show’s the isometric angle at 35.264° (marked green), taken from the diagonal of a cube.
I’ve created several different angles that you could use. Yours was maybe around 54.736° (marked red)

see:Isometric_axonometric_projection.skp (285.1 KB)

p.s. Use ‘Position Camera’ (=drag the icon along a dashed target line) to create a view with a specific angle. Do so when being in ‘Parallel Projection’ mode.


#12

That´s the way you got the 54,736 angle?


And why this specific angle (54.736)?

In fact, I was wrong to say in axonometric view. What I’m looking for is a way to represent in military view, directly in SketchUp.


#13

I just guessed from looking at your image before.
I guess I came close to a similar view.
You constructed the angle correctly. I did 90°-35.264° (= green isometric angle) = 54.736°

The military view is in fact a view of a distorted SketchUp 3D model.
You’ll have to create that distortion from a normal 3D component instance. The floor and any horizontal planes are viewed in Top view.


#14

Had you asked the question in this tool’s thread at SketchUcation then I might have seen it earlier !

The axo4545 gives you something like you want BUT because the vertical heights are viewed from above you need to scale your model in the Z [blue] direction [by 9.068229097] as set out in the tool’s explanatory pages…

I think that you cannot produce a true [looking] Axo in Sketchup without Z scaling…


#15

The Wikipedia article from which it appears your image was copied clearly spells out that isometric is the only variant of axonometric projection in which all three axes are equally foreshortened, hence the only one in which you can compare lengths along the axes. In the other variants, one or more axes are foreshortened differently than the others and must be scaled if you want to have equal lengths displayed in the projection for equal-length edges in the model. In the “military” projection the x and y are foreshortened equally because they are viewed at the same 45 degree tilt, but the z axis is different and, as @TIG pointed out, must be scaled accordingly.

A key point here is that there is a big difference between drawing an image of something in an axonometric projection on a 2D plane from the start (in which case you lay out the projected axes and measure lengths along them while drawing), versus taking an existing 3D model and generating the equivalent 2D image from it. The latter requires choosing one of the axes as reference and scaling the 3D model along the other axes to achieve the same projected lengths in the 2D image.


#16

That is because it is not an axonometric projection but a plan oblique.
To be honest, parallel projections (except plans, sections and elevations) have become redundant as design is today performed with computers so we have no need for 3D-ish views that look weird because they are easier to construct by hand than perspectives.


#17

Thank you guys!!!

Thank you all!!!

#18

As I said, it’s not impossible
You need to set up an environment where your modeling space is inside a component.
Another instance of what you model should then be inside another group or component which is distorted properly to get you the right angles: 135° / 90° / 135°
If you set things up right you can even get x and y with the correct proportions.
I didn’t go as far as setting up y to also get the correct proportions. It’s should be a matter of scaling the second instance in the z direction.

So you can get your military projection on screen, maybe even print it (straight from SketchUp or through Layout.

Personally I see no value in these sort of projections. I even prefer to always work in ‘Perspective’ mode in 3D. And I’ll use the standard views in ‘Parallel’ projection otherwise.

#19

me too, but I think that in some cases, as in the representation of a room seen from above or an urban project, the military perspective shows better the distribution of furniture (or buildings) than the isometric.

For the representation of objects, such as a chair, for example, the parallel perspective and the 3-point perspective are better.


#20

Well, you can model inside the left component instance. (the cube will then be redundant).

The other instance in military view will follow the changes as you wished.
