Newbie question: From a 3D model, create an axonometric proj. w. axes and ticks

[Anonymous]

Hi!

AutoCAD, first day. Not so bad; in front of me is a solid object, created as union and set difference of a bunch of cuboids (see attached screenshot).

What I seem unable to do or find is this: I would like to plot or print an axonometric projection such that the projected Z axis is "up" (on the paper), the projected X axis is left/down at a 110° angle CCW from the projected Z axis, and the projected Y axis is another 135° CCW from theprojected X axis.

All three axes should show fifteen ticks for 15 cm of drawing size. The projected Z axis would be 15 cm on paper, the projected X axis would be 6 cm (so the scale would be original:projection = 15:6), and the projected Y axis would cram the 15 ticks for the 15 original cm onto a paper length of 9 cm.

In an ideal world, I could also choose to have some of the planes spanned by my axes to be drawn as grids ...

I am quite sure that I am too ignorant, too stupid or perhaps both to recognize an elegant solution that AutoCAD surely offers; but having gotten lost in layouts, I am quite comprehensively humbled and hope for help.

Thanks,

Felix.

Hi,

Your solution will be with layouts and viewports.


You can add multiple viewports to a layout (_VPORTS) and in each viewport you can set a different viewpoint or even change the UCS to get the right angle. You can also freeze and turn off layers per viewport. To do such a thing you dubble click inside the viewport (the viewport will now appear bold) as long as you are inside your viewport you can work as if you are working in your model space, including the commands _UCS, _LAYFRZ, etc. Doing this you can set the right angle at which the viewport should look at your model space. 

To set the right scale and the visual style I suggest you use the viewport properties. For 'top' view etc.. It is handy to use the viewcube or named view options. It is good practice to lock your viewport once you are content with how it is set.



The easiest way to do this would be to draw a reference axis in your model space (perhaps on a layer that does not plot) and when setting the UCS for your viewport picking the 3 points on your reference axis.

To represent your axis's with ticks in your layout you can either draw this in the model space, or you can just draw them in your layout.

If your scale is set correctly you can easily determine the length of your axis. I would use the _DIVIDE command to mark all the places where you want to set the ticks.

But it might be easier to use the Scale Bars that Autocad provides in the Layout Tools. 

Maybe somebody else can give you more practical tips. Until then I hope this helps and sets you on the way.
