I have created a model which is oval shaped and the size is quite specific. I need to send it out as a dwg file as it will be opened on NX12 to be then cut on the CNC machine. The problem i am having is when i export my file and he opens it on NX12 he can see the model but cant see the lengths. How do i export the file so he can select a side he wants and see what the dimensions our or is this something that has to be done with sketchup. THanks for the help in advance.
