I have drawn some components for a model steam locomotive in 1/32nd scale. These parts, drawn full size, are quite small. I wish to produce a copy of the parts, but enlarged to twice full-size (magnified effect). If I select the component, copy and paste it to a another part of the drawing, so far so good. However, if I then select all the entities of the part, and use the scaling boxes on the editing bar (changing the scale values from 1 to 2, some entities are enlarged, but some remain the same size - eg the x distance may increase, whilst the Y values remain the same. I stress, that this only happens to 'some' entities, not all of them.
The second problem is that the associated dimensions are also doubled in size, when in fact I wish them to remain the original value.
How can I achieve an enlargement of a part of a drawing with the correct dimensions?
