Imperial vs. Metric Sheet setup issues

Hello:

This is my situation: I received drawings and a titleblock originally drawn in imperial units. Now, I need to set them up in sheets with metric-based units, specifically meters.

I imported the drawing and turned them to metric units. Now everything I measure displays the correct dimension in meters (ie. a door is 0.90 wide, the walls are 0.10 thick, etc).

Then, I went to the paperspace and set up an Arch D sheet, making sure that the scale is 1:1 and the units selected are mm. So far so good (I think).

However, two issues arise (or perhaps it is the same issue, I don't know): The first is that, when I insert the titleblock directly in Paperspace (as I have been asked to do), I don't seem to get the scaling right. I thought it had to be 39.37 but it is way to small compared to the Arch D "shadow" in the paperspace. I tried to scale it in increments of x10, but it never fits correctly before going way to big. I have verified that this titleblock does work in all-imperial setting for Arch D size.

The second issue, the one I am mostly worried about, is that when I tried to create viewports in scale 1:100 (the scale it is suposed to work), it is microscopic-small. Only when I select something like 10:1 does it fill the Arch D sheet "shadow" in the Paperspace.

Hopefully I was clear enough, but I would be more than happy to provide further clarifications.

Thanks

I've never had this problem so....just a shot in the dark, but from what you have posted this part threw me off:

then the next line down you posted:

I would assume that if your having a scaling issue it is because you are using two different units even though meters and millimeters have the same base unit. Might be worth a shot.

You are absolutely right. That was the problem. For some reason, I thought ACAD would correct this automatically, but of course it doesn't. What I did is that I changed the plot scale to a custom 1000 to 1 and everything fell into place.

Thanks,

if you scaled it by 0.3937 you can get back to the 1:100 viewport scale.
