May find that using an axonometric cavalier to present objects?
I have periodic requests for this from my students, yes…
Hey, what do you recommend to get accurate isometrics- and axonometric-views ?
I change the the perspective viewport to ‘parallel projection,’ but then it’s tricky to hit an exact 30°/60° axon or 45° isometric view. Any suggestions?
A “quick and dirty” workaround would be, to make a copy of the object you like to show and rotate it exactly 30/60/45°, so you can stay in your normal top/front viewport.
I use the function rs.XformChangeBasis2 in Python script for deform the object
Here’s an example of what I am after. It’s a few simple settings, but it does take a few steps to get it looking right. I can share my settings if anyone is interested.
There is the command
_IsoMetric for 45 deg angles.
Maybe it can be extended with 30deg increment angles
I always used to place camera&target along predefined "vectors"aka line segments that correspond to the needed angle in an parallel view and then zoom selected onto the objects I want to show.
you can build your own little “view cube” … with bells and whistles where you have a visual reference of your different vectors.
May I shamelessly plug a plug-in (plug a plug-in, get it? ) that I wrote a couple years back?
@menno, I got a

A search on Food4Rhino shows this one:
FWIW, also see these threads on the topic:
oops, thx for the correction!
Is there also something for this one?
@Mikko once made a formula for this projection, more than 10 years ago.
degrad = 0.01745329251994 raddeg = 57.29577951308 a = 7 b = 42 'Then using Mikko's notation (note:sqrt is the squareroot function) TanA = Tan(a * degrad) TanB = Tan(b * degrad) alfa = Atn(Sqr(TanA / TanB)) beta = ArcSin(Sqr(TanA * TanB)) 'Now plug these results into Mikko's formula for camera position p1 = Sin(alfa) * 1000 p2 = -Cos(alfa) * 1000 p3 = Tan(beta) * 1000 'The result for the values you gave (7-41) is .3518,-.93607,.34567. However, 'this won't give you very accurate results since rhino rounds off the values to 'two decimal places. So what I suggest is that you multiply the xyz values by '1000. so that the values you place in the camera position field would be '(351.8,-936.07,345.67). Debug.Print p1, p2, p3 tp1$ = Format$(p1, "0.00") tp1$ = Replace(tp1, ",", ".") tp2$ = Format$(p2, "0.00") tp2$ = Replace(tp2, ",", ".") tp3$ = Format$(p3, "0.00") tp3$ = Replace(tp3, ",", ".") x$ = tp1$ & "," & tp2$ & "," & tp3$ Text3 = x$ All$ = "PlaceCameraTarget " & x$ & vbCrLf All$ = All$ & "0,0,0" & Chr$(13) & vbCrLf Clipboard.SetText All$
Wow. I never saw that! Amazing & thank you.
