EatingSteak Posted April 15, 2015 Share Posted April 15, 2015 I have some US components - in feet & inches - that I need to put onto mounting plates and cabinets that are all metric. Comparatively, the components are very complicated and the cabinets rather simple. My drawing is staying in feet & inches. However, for the plates, I need to move lines by a metric amount - like 25mm. Obviously, if I hit [M][Enter][25][ If I do an arithmetic conversion, it's going to be 0.9842519685... inches, but that will introduce rounding error. Is there any way to get an exact value here?

dbroada Posted April 15, 2015 Share Posted April 15, 2015 the simple answer is no. Drawings are done in "units" where 1 unit is whatever you want it to be but you can only have one unit system within the drawing. As the cabinet is the simpler item I would scale it by 25.4 and then continue in only metric. Quote Link to comment Share on other sites More sharing options...
ReMark Posted April 15, 2015 Share Posted April 15, 2015 Why not use decimal inches instead of feet and inches? Wouldn't that be more accurate? Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 15, 2015 Share Posted April 15, 2015 I do it way too often. Just did a few drawings today like that. I set up the drawing with -DWGUNITS and select yes to insert items at the drawing scale. There are a few options for other system variables for insertion units, that sets everything up for you. You can set up a second dimstyle for the metric or use alternate dimensions or adjust the dimensions individually through Properties.

Dadgad Posted April 16, 2015 Share Posted April 16, 2015 Why not use decimal inches instead of feet and inches? Wouldn't that be more accurate? I typically work in mms, our fabrication is done in China, but when working on projects stateside, if the fabrication will be done there, I am forced to use inches, which I hate. Decimal inches makes everything easier, compared to converting them to metric, but rarely does one see a tape measure with decimal inches. No doubt, Starrett and other high end companies sell them, but not too many people have them handy. In such cases I just do an Inch based drawing (or use -dwgunits if need be), and create and use an Imperial dimstyle, rather than using the alternate dim display.

ReMark Posted April 16, 2015 Share Posted April 16, 2015 It seems like a recipe for disaster whenever you starting mixing units (ex. - imperial template and metric blocks). Why not stick with one unit and dimension using alternative units (i.e. - show both metric and imperial dimensions)? Quote Link to comment Share on other sites More sharing options...
mdbdesign Posted April 16, 2015 Share Posted April 16, 2015 Found it on "TheSwamp" and it work great for both templates. Instead of typing (inch template example): [M][Enter][25][ type: [M][Enter]['mm][25][ and done. PS: sorry for not wrapping, tags not working. Inch2mm-imm.lsp mm2inch-mmi.lsp Quote Link to comment Share on other sites More sharing options...
nestly Posted April 16, 2015 Share Posted April 16, 2015 Can your "components" be blocks? If so, when inserted they should automatically scale to match the host drawing. OSnaps should solve the rounding issues. Quote Link to comment Share on other sites More sharing options...
EatingSteak Posted April 16, 2015 Author Share Posted April 16, 2015 Thanks mdbdesign, this is awesome - didn't expect any solution that simple. Quote Link to comment Share on other sites More sharing options...
