HELP??? I have designed an antique punchcard in Make, with very precisely spaced tractor feed wholes and precisely spaced patterning holes, and can not get a print out in real size. I have tried exporting in 1:1 scale but it is NOT in 1:1 scale when I open the PDF. The hole spacing has to be extrem…

Does this work? I deleted the guide points and moved the top set of holes closer to the bottom set. I also moved them to the origin because placing the model at a long distance from the origin is a bad thing. [image] This is the Print Preview pane, then, showing that the two sets of holes will pr…

That preview looks more like the ones I got in the SSDE+ program that were off by tiny amounts by row 40… and the margins look about right. I had the horizontal spacing figured out. it is the vertical spacing over the length of the card that is giving me fits. it isn’t a normal spacing… I originally…

In order to be able to print to scale, the camera needs to be set to Parallel Projection. When I opened your SKP file, it was set to Perspective.

Denisroy, yours looks just like what I have been getting. the margins tell me immediately that it is too small… when printed the vertical spacing was actually about 4.05mm vertically by calipers. Thanks, for helping me try to figure this out… when designing in SU for woodworking projects I have neve…

I swear it was set to parallel when I started out!! Blast! I just moved it closer to the axis and reset it to parallel, so let me try printing once again…

Holes.pdf (209.7 KB) How does this PDF work out for you? Print it with no scaling (that’s a setting in Reader/Acrobat) and measure the spacing.

Well… I just report what I see. The thing is, this same sort of thing could be useful in woodworking, too.

is your viewport set to the paper ratio? do you have a scan of an original card… [image]

The spacing in the holes.pdf was too wide… I may have to actually export as svg and cut a couple of pages… maybe first and last rows… I just hate wasting paper. Yes that is a Jac40, There were actually three such devices made for different gauge machines: Jac40 (blue) tines spaced 4.5mm apart for s…

The dimensions I showed in the PDF are based on what you drew although they get rounded. The actual vertical spacing is 5.25 mm. If they aren’t correct, that’s because of your spacing and not the print out. Exactly what spacing are you looking for?

Printing or exporting 1:1 scale- is this possible?

5 mm horizontally. What are they supposed to be vertically?

Not possible to print a dead-simple figure in real size if not a professional? (answer: margins and window-fit)
