attached the test file, to see what happens to a 100mm x 100mm box and its line weight test lines and circles.
method to establish what weights to apply to lines for desired appearance in photoshop.
By the way why doesnt a 1mm line weight have line filling out a 1mm high row of grid squares , and others drawn likewise the expected thickness ?
Print preview doesn’t show lines at their thickness given, making for line weight use and visual design impossible for establishing effect.
That extra issue aside, I select box and contents and go File>export Selected> pdf and select 600dpi.
However I see inches indicating some odd size of 8.5 inch x 11inch, and a large white preview with all the page contents small in middle.
Open the pdf into photoshop, choose 600dpi, which in eps mode would make the file same size dimensionaly as in source prog, so our box would be 100 x 100mm, preview pane shows though all objects…oh dear…
It opens and our 100x100mm box is 35.5mm x 35.5mm and all items have been exported ! also text gone massive.
No way can I use this export box around various features as I export them , acting as the means of keeping scale same for all exports, whether its a single rivet or an entire cowling or aircraft, box would be a bit bigger than 100mm , it would surround the entire subject side view, and then I assemble them as layers in pshop… as is the done practice with eps.
Export selected and choosing pdf is simply ignoring the selected items !
