Exporting 1:1 .dxf not working


#1

Hi!

I´m trying to export to .dxf for lasercutting but the scale is off. I´ve set view to parallel projection but when I go into exporting options the 1:1 option is not available and I can´t scale it manually. If I set both drawing and model to 1,0mm the width and height go bananas. If I try to enter A2 measurements into the width and height they go bananas.

Basically I can´t get a 1:1 scale on export.

The screen shot indicates you aren’t exactly on a standard view. In Parallel Projection with the standard top view, you wouldn’t be able to see the blue axis.

I did. Top left corner says “top”.


#4

Select the Top view and Parallel Projection again. If it was really the top view, the blue axis wouldn’t be visible.

Weird, now it works. But why can´t I manually enter the A2 size of 420x594mm?


#6

The .dxf ends up being 420x805,7mm not 420x594mm.

What am I doing wrong in Sketchup?

There´s some invisible weirdness going on. If I make it into a component it looks like this:

There´s nothing there?

Can you upload the SKP file so I can have a look? There’s got to be something there.

Sure!

Some where in the box there’s a line segment that is ~0.6mm long.

I found it by opening the group for editing and then dragging a right to left selection box through the bounding box without hitting any of the geometry I knew you wanted to keep.

After hitting Delete and closing the group, selecting it shows it as you’d expect.

Thanks, I got it! I must´ve screwed something up. Noobie alert! :slight_smile:
