Make 2d > third angle projection

a.p.haythornthwaite · January 24, 2020, 10:09am

when creating 2d > third angle projection drawings of parts, is there away to keep the perspective / isometric view of the part full size and to match the perspective view port [which I currently have set to parallel.

I used to do this in rhino 5, but has changed to a ‘snap shot’ in perspective view in rhino 6.

my current work around is to create the third angle drawings delete out the perspective drawing, then go back into my parallel view and generate a new drawing of the using the ‘view’ option.

Thanks,

Not sure exactly if you already know the feature (side panel) named views?

example:

Hi, Thanks for reply.

I am aware of it, but have not worked with that much.

I just had a quick look / play, but was unable to see how this can help with the the make 2D output settings… do you know if this can indeed change the output setting for the third angle projection so I have a full size parallel drawing of the part?

Thanks,

Andrew

Hi Andrew - we have an unsolved ticket for this issue - RH-641 (not open to the public).
I’ve added your request and a few comments to that ticket.
Thanks,

OK. Thanks for update Wim…

HI Wim,

Just checking to see if this issue has been updated / resolved?

With regards,

Andrew

Hi Andrew,
I’m afraid that’s still open at this point. I’ve given it a bump.

Hi, could you please give it another one? I can’t say how many hours I have already lost during the last 4 years doing exactly what Andrew does - making a third angle, deleting perspective and making a parallel drawing by hand. And one more thing - the scene silhouette doesn’t work more often than it does so I disabled it completely and do th outlines by hand - I use Hatch (boundary), deselect all the hollow parts by hand, DupBorder, delete the hatches and move the borders to make2d/silhouette layer. And this workflow generally gives me what i want (or at least 10x more often than make2d itself). Maybe something similar could be used as the silhouette solver in the make2d command, which for now I believe calculates the silhouette on the 3d geometry.

Hello - Is it the relative scale or the projection of the oblique view that is incorrect?

this is what I get:

Is that what you expect?

igorjansen94 · January 21, 2022, 11:32am

this is what I get

this is the view i get it from

and this is what I would expect to get from this view

I Igor -

Could you please run the Rhino SystemInfo command and copy-paste the result here?

Hi Igor -
Thanks for that information.
I can’t reproduce this behavior here. I see that this looks like a simple example, but could you please post the 3dm file so that I can see if I can reproduce that with that model?

Hi Igor -

Thanks.
You have 4 viewports, of which 3 are parallel viewports and 1 perspective. Currently, this will cause the Make2D command to take the perspective viewport as the 4th view in the output, the other 3 become the regular top, front, and right views.

The workaround is to either put the unused perspective viewport into a parallel projection or just close that viewport (CloseViewport).

To change the current behavior requires a bigger rewrite of the command. This is on the list as RH-3557 and will be looked at for some future version of Rhino. I added this thread in a comment.

a.p.haythornthwaite · March 22, 2022, 6:05pm

HI PAscal,

How are you achieving this output?

I am not getting this my end at all - its still the same as before, where I have my 3 parallel viewports and one isometric. And I still get a perspective output…

This is the model, showing my viewport panels above

and this is the output running make2d

wim · March 22, 2022, 7:32pm

Hi Andrew -

Could you upload your 3dm file and post the output from the Rhino SystemInfo command?
-wim

a.p.haythornthwaite · March 23, 2022, 5:41pm

HI Wim,

Thanks For getting back…

So, I have found something… It would appear that if you set the view port to isometric SE [or whichever orientation for that matter] and you DO NOT rotate the view, it will give you a Isometric / parallel output in ‘make2d’

However, if you rotate at all the view [which I often do to get a preferred view of the object] then it gives a persp 2d output… even though it is still in a parallel viewport

I am not sure why, but for some reason I am unable to upload my .3dm file - so please see screen shot of out put results.

and here is my system info below:
