I’m trying to use Carbide Create for the first time.
I created a simple square 10x10mm on Autocad and I use mm as my units on CC.
The square gets imported but it’s 254x254mm so it’s imported as 10x10 inches instead of 10x10mm.
What am I missing?
You’re not missing anything — DXF doesn’t include a concept of units, and programs tend to make assumptions — I just draw a rectangle of known dimension around everything, then after import, select everything and set it to that size.
Thanks for your reply.
I didn’t want to believe that Carbide Create uses only inches while importing.
I design everything in metric so I have to scale them down.
The problem with scaling is that CC has a scale factor with 3 decimal points so if I use scale factor 0.039 I lose accuracy.
For example a 100x200 square in dxf format is imported as 100x200 inches (2540x5080mm) and after scaling it down it becomes 99.06x198.12mm (I’m losing almost 2mm)
I think I should scale up my design with a scale factor of 3.937 and then scale it down with scale factor 0.01.
Excellent point about the precision — I really wish that all developers doing this sort of thing would use integer math and a suitably small base unit (can anyone say scaled point?) so that this sort of thing isn’t an issue.
Really wish I could measure in 16ths of an inch in Carbide Create.
