Restrictions
Not all elements and attributes in Arbortext IsoDraw can be depicted as DWG elements.
Masked Elements
The element used as a mask and all masked elements are grouped together, but remain visible.
Fills
Fills cannot be depicted in DWG format.
Halos
Halos cannot be depicted in DWG format.
Pens
It is not possible in DWG to define line thicknesses except by converting all elements to polylines. Since polylines are particularly laborious to edit, however, Arbortext IsoDraw employs a different system.
Each element is assigned a color when it is exported. Every Arbortext IsoDraw pen generates a different color. If, when plotting the file from e.g. AutoCAD, you use plotter pens for each color that match the respective line thicknesses, the appearance on the paper will be correct.

|
Line width transitions on ellipses are exported as polylines of variable width. If the drawing is scaled, these transitions will naturally change also. Note that you will then have to use other pens to ensure that the transitions once again match the line thicknesses.

Since a pen can only be exported as a color, the information on the color of the pen is lost.
Image Elements and EPS Documents
These elements cannot be converted, since DWG has no corresponding element types.
