Hi. Unit selection may be wrong in DWG import options. If you made a mistake here, the drawing may have been too small. When you change the unit in the import options, you can see the drawing dimensions at the top. You can also give it a scale. If you are going to use the drawing as a base, it must be 1/1. Use the Distance command to control a dimension that will be a reference in the drawing. For example, if the column edge size is 30mm instead of 30cm, you need to enlarge the drawing 10 times. Use the "Scale (reference) command to enlarge it. In our training video, the use of DWG drawings as a base is explained in detail.
