I have note some Autocad limitations, but it's possible there is a solution about them (i refer to the 2002 version): 1) when you select "cut" you can cut only one line at time and not multiple lines 2) when you are sketching a section the operation is not possible if the part is not completely contained into the screen when you activate the command. The same problems appears when you select objects from right to left: if the objects are not completely contained into the screen not all of them are selected. Is there a way to avoid these problems?
