-===== Using Fusion 360 =====+  * If extrusion fails 
 +    * This might happen when there's a small surface present. To find and delete it, do the following: 
 +    * shift + click the top (and bottom) surface and delete them. 
 +    * select the walls and 'explode' those. 
 +    * enter the command ''selsmall'' and add a value that's a fraction larger than the object's extrusion. For example: a shape is extruded 2mm, enter 2,001. This finds shapes up to that length. So the smallest surfaces are found this way. 
 +    * if the command found one or a few super small walls, delete them. If there's no gap, that should be good enough to go. If there's a gap, try adjusting the surfaces boundaries to match or fix the gaps with the ''connect surfaces'' icon. 
 +    * When the walls look OK again, click the icon ''surface from planar curves'', then select the tops of the walls and press OK.  
 +    * Repeat for the bottom parts if necessary 
 +    * Join the fixed part to the rest of the solid model. 
 + 
 +  * Export as STP file 
 + 
 +  * Import STEP file into Fusion 360 to create toolpaths the regular way. 
 +  * Use flat end mills
