Experiments in Rhino into Photoshop


#1

Hi,
Pondering on best way to get Rhino into photoshop as 2D.

I see Pshop opens 3ds and Rhino exports 3ds, thats probaly for the 3|d aspect of photoshop.

however I am first trialling export import as Adobe Illustrator, there being no eps export option in Rhino which worked a treat in Freehand to Photoshop., by the way why cant we have eps export ? its a universal language between progs.

attached a 1000mm x 1000mm box using hairline lineweight to hopefully make the result 1000mm x 1000mm

If bounding box with test boxes is at origin for its lower left corner, export selected, as Adobe Illustrator, it imports as 1000.48mm hgt 1000.48mm width

if its lower left corner is at x 100 and y 100 it imports no longer square ! 1797.4mm width and 1729.67mm height.

Why ?

I might not have things to export always at origin.

Also I wish to create an aircraft profile from my aviation 3D work, export it into photoshop and colour it up in cmyk.
Line weights dont show unless print preview is on, but then as one zooms they get fatter and fatter until they touch !


At what zoom are they relative to each other, the right proportions. i.e. if I have two panel lines 1mm line weight 100mm apart on the full size aircraft, there will be a certain zoom that portarys this appearance, zoom further out and I can get those panels to touch.

How do we get the line weight to not get thinner or fatter as it s hellishly confusing when trying to create the right look if trying to draw something to look right. display grid at true screen size would be the command, does it exist ?.

The weights display correctly in photoshop I am relieved to say.

text used was Arial, Photoshop also has Arial, yet when I open the ai export from rhino, pshop says …The file uses one or more fonts which are unavailable on this machine, open anyway ? I click continue and get a different looking font and the word weight is now weigh.

If I explode the text, and leaders take two explodes, how can I fill them solid ?

An way of applying cmyk fills to 2D shapes, if all is drawn in e.g. Top view ?

So if I alter the shape of something the fill updates, unlike in Photoshop I would have to repaint the shape.

There is an export cmyk, as RGB fails photoshop, but the colour choice is only RGB from what I can see. I would also like to be able to alter all instances of a colour with a revised colour, can one do that ?

anyone able to assist here ?

why does square go rectangular when corner not at origin when imported into photoshop ?

what is the method for rhino into photoshop ? 101 views so far, does no one know how its done ?

why does Arial rhino not equal arial photoshop, its the same PC font !

keep line weight from going fat as zoom out ?

any cmyk fill option for 2D shapes ?

anyone ???
I need to urgently take rhino work into photoshop, and avoid these quirks., but how ?
Can someone do a plugin or code to convert rhino to eps ?

I guess you’re the only user who tried this and no one like the idea of working with drawings in Photoshop…
What is the purpose?

Hi,
having drawn up an aircraft in Rhino3D, I need now to start creating colour profiles of this aircraft, so having an accurate set of panel lines etc, I need to get these and maybe also coloured up areas across into photoshop as layers, to start using layer types/styles and so on and create quality profiles.

Actually, according to this post it is.

If you need, in my opinion an antiquated format, like eps, (do they still make PostScript printers?) just export your AI to eps. I have asked that they update the AI output to a modern AI format and not use eps.

Have you tried going from AI to PS with the rhino file exported as AI ? Why PS anyway if you want to use cmyk? PS is an image & monitor based application, while Illustrator is a print application. Take a pantone colour and see what it looks like when RGB in PS and CMYK in AI, they don’t always look the same.

The issue of size depends on which side, or centre, of the curve AI puts the stroke. I am not sure I would expect raster to be as precise as vector, especially a crude image format like jpeg. What is the dpi of your PS work, that will make a difference when converting from different formats. I export an 8 ½ x 11 page in Rhino, open in illustrator and then export to PS and save as png . Open it and my image is like 11 x 20 inches. Photoshop doesn’t work with print scale, that is not it’s forté.

If you need exact measurements like you are trying to show, don’t use PS. It is like trying to slice bread with a butter knife.

We do these paintschemes with a combination of PDF from Illustrator and DWGs from Rhino and CATIA.
We might cook up a quick Photoshop job on top of a white aircraft rendering from time to time.

Hello Steve1,
From my experience as an architect, you have two options based on your goal:

-to transfer geometry (1:1 scale): you simply save as Illustrator’s *.ai or *.dwg and move on to Adobe Illustrator.

-to transfer drawing with correct scale and lineweights: create a layout and print to PDF. Then move on to Adobe Photoshop or Illustrator. Lineweight doesn’t make any sense in model window and keeps the same thickness on screen both in Rhino and Autocad. However, if you create a layout (A3 format), place your drawing, give it correct scale, turn on Print Preview, then it stays 1mm thick on the paper, no matter how you zoom in/out.

Hope it helps. Ask me if you run into any further trouble.

Hi,
I use PS because I use the layer options to get the panel lines to show the appropriate effect on a colour, so multiply gives me certain effects,
I apply highlights and shadow in the same manner over the various aircraft colours. I have to apply airbrushed mottling using the spray brush as it would have been, I use channels to create and mask areas when doing so. I apply weathering etc.
All to a colour calibrated screen.

I can use distort tool to marry an oblique shot to a 2D view to trace off codes and markings.

Photoshop enables me to do all this.

In the past I would swleect panel lines, exxport as eps, open into PS and they would be in register with everything.

This business of exporting as AI and it screwing up my original shapes… [quote=“Steve1, post:1, topic:37552”]
If bounding box with test boxes is at origin for its lower left corner, export selected, as Adobe Illustrator, it imports as 1000.48mm hgt 1000.48mm width

if its lower left corner is at x 100 and y 100 it imports no longer square ! 1797.4mm width and 1729.67mm height.

will mess that up, thats distorting my work, nothing will fit. Eps export from Freehand never did that. Itv was an export option called eps, and it worked.

I’m sorry, I have trouble importing my test file to Photoshop but in Illustrator the square stays 1000x1000. Maybe you could upload your test *.3dm and *.ai. As I suggested before, you could also try to print layout in Rhino to Adobe PDF and see how it works.

hi,
files attached

got there in the end.

also sending the ai exports from Rhino to someone with Ilustrator they say:-

I’ve opened the files and both open in an A4
landscape page. The file with the origin at the bottom left opens partly on an
A4, the other one is miles away from it. Both images are still 1000 x 1000 its
just that one of them is ‘on’ the page and the other is far from it (I’ve
attached a screen dump of both). I’m not sure why it has placed the image where
it has – there doesn’t seem to be any logic to it.

On a positive note, all of the pen weights and boxes are all correct in size.
