You have to make shure that the DXF you want to make your board Outline i one Poligon and not seperat segments of lines.
- ues the Join and Creat Polygon butten to Assembly your DXF to one Polygon. (can be tricky)
Edit --> Modifye --> "Allow Cell Graphic Edit" is enabled
Select your Polygon and switch its Drawing Type From "Drawing Object" to "board Outline"
Instead of importing dxf and using this as board outline ask IDF emnemp from the mechanical team and import to PCB so that the board outline will come as such
and you will not be able to modify this . The hieght restriction all the data come as such
even while exporting the dxf if it is exported as a single entity it will not split into segments
If you were no able to get the IDF file open the library manager go to cell editor and select mechanical cell ceate a new mechanical cell in the cell editor import the dxf file and set origin at the bottom left most corner now save and close now place the mechanical cell use place option
now either you can set the origin at the bottom left by finding the bottom left point in the dxf
now ensure that the dxf is imported as a closed object if some dis continuities in segment if segment of lines are not closed fill option will not de enable
if it is having separated line segments merge the segments to a single object now if fill option comes you can double click on the line by pressing control key
you can copy the object and change to board outline but while importing to cell editor ensure the unit mills or mm
if the board outline is definite shape just draw the shape but for customised shape go for the import option
you can also use the default origin and move the cell to the origin by using snap point
