With its many benefits there is also a host of difficulties. The main one being that having two or three drawings open at about half their normal size, manipulation, cutting, and pasting from different drawings with accuracy is extremely difficult to achieve. Speed - IntelliCAD is much slower than all AutoCAD versions in essential areas such as drawing loading, saving, drawing regeneration and area zooming. No Mtext support - This will cause an inability to keep text properties and the user will ultimately be required to fix text properties in drawings such as alignment and positioning. No immediate scaling - it is extremely arduous to draw in full size and only be allowed to scale when plotting.
Scale is an essential factor which gives the user ease and sense of layout and positioning.
It can be saved for when starting a brand new drawing as the default setting, but every time an older drawing or one created in AutoCAD will have to be loaded and the settings changed. No digitizer support - The program is capable of using digitizers and corresponding tablets which may drastically decrease efficiency. However, there are still some parts missing and I feel that an AutoCAD user trying to convert will have some hard times. The program will nevertheless be superb for a newcomer to CAD, and I think that the IntelliCAD sets the standard for future programs. A very low system requirement is also helpful for those designers who move a lot and need quick access to drawing while retaining most AutoCAD utilities.
