Drawing Options

[vittonej]

When I open sheet cam and import an image, The drawing option box opens with metric, inch and custom, I click on inch or the inch is checked, but the inch box has 25.4 already in it and I need it to be 1:1 and it has 25.4, and I can not change it is grey, metric is 1:1 and custom I can change, but when I use custom the drawing will be messed up, but when I run the part it will be 4 times bigger
I am beating my head against the wall

click on the custom button and you can change the scale.
What I have found is you need to measure the drawing after it appears on the screen. use the curser on see the size at the bottom of the screen.
It helps to have the drawing appear in the lower left so the left side is at 0 X amd 0 Y then you can measure to the right or up to get your size.
If it is not at the size you want you will need to click "new Job" then answer no to save.
Then import the drawing again and change the scale until you get the size you want

Is the original DXF or whatever, being output in Metric and not English units?

I set the drawing program up for inches but it seems a file saved in SVG format appears in SheetCam in a different scale and I need to play with it to get the size I want.

I set the drawing program up for inches but it seems a file saved in SVG format appears in SheetCam in a different scale and I need to play with it to get the size I want.

I used to have that problem because I thought SheetCAM would only read DXF, so all of the vector drawings I made up in Inkscape were converted to DXF. That's where the scale problems begin. The conversion seems to always be 25:1 or vice-versa when opening DXF files in Inkscape and it gets worse from there.

That's why now, if I download a DXF design from here, I first open it in QCAD and then convert it to .svg, then open it in Inkscape and scale the file to a 1:1 size I want to cut, THEN When I import the .svg picture into SheetCAM, I use the same 1:1 and it works fine from there.

If this is confusing and you need more help; let me know. I am seriously considering doing a YouTube tutorial on this subject, but Arclight has already done a few themselves that are pretty awesome!

Good Luck
