When converting an imported CAD body to implicit using the Implicit Body from CAD Body block, the objects appear to lose detail / is tessellated but one would expect the implicit body to match the CAD body exactly.
Importing and converting small parts or small details on a part.
This is happening because the Tolerance on the Implicit Body from CAD Body is too large to capture the details of the part. The details become merged into each other and are not representative of the true shape.
Decrease the Tolerance to be small enough to capture all the details of your part.
