Open the file ACA3-02.dwg. What is the distance between the 2 desks on the left?
At first sight it appears that there appears to be only one desk on the left hand side. The reason for this is that there is additional data on a layer which has been frozen. Go to the layer control button and you will find that layer 0 has been frozen. Use the Di distance command to measure the correct distance.
Use layer control button to access and thaw layer 0
When you freeze a layer in Autocad, data on that layer will be ignored. So the working size of the drawing data will be smaller. This is often used to speed up drawing on large files, though not so much of an issue these days as we have more powerful computers.
