Fuzzy Offset : Options and Results

Access: Open this function from the following location:

Select Faces > Create Faces > Fuzzy Offset from the menu bar.

Create an approximate offset surface out of a complex skin surface.

The Fuzzy Offset feature is mostly required for Die Casting and Mold use cases; for example, for creating the reverse side of the die/punch head.

Notes:

For best results when working with this function, it is recommended that:
- The original skin is smooth.
- The object is plane projected (no vertical or semi vertical faces in the "projection direction").
- There are no holes in the skin object.
The function may also work in cases where the above requirements are not met, however, the results may be unexpected.

The result always has a rectangular shape and all holes, if they exist in the input surface, are closed in the offset surface.

Example reference input surface:

Required Step 1

Pick an open object and set the offset parameters.

When the reference input surface is selected, a flip arrow is displayed; set the offset direction.

Parameters:

Fuzzy Level

Set the fuzzy level accuracy from the following dropdown list of options:

Fuzzy Level = Loose	The loose level system performance is the fastest, however, it is the least accurate and produces a smoother face. See the example images below.
Fuzzy Level = Medium	The medium level system performance and accuracy levels are between the Loose and the Tight levels. This is the default option. See the example images below.
Fuzzy Level = Tight	The tight level system performance is the slowest, however, it is the most accurate and produces a more wavy face. See the example images below.

Keep Original

This is a toggle option Keep Original / Remove Original, that enables you to either keep or delete the original object.
Default: Keep Original.

Offset Value

Set the offset distance.
Default: 5 mm (0.2 inch). Minimum: 0.
Examples:Examples:

Offset Value = 20:	Offset Value = 100:

Extend Boundary

Extend the boundary of the offset surface.
Default: 0 mm. Minimum: 0. Maximum: Unlimited.
Examples:Examples:

Extend Boundary = 0:	Extend Boundary = 70:

Click OKOK or ApplyApply in the Feature Guide to complete the function.

If the Offset Value > 0 and there is an intersection between the reference surface and the offset surface, a message is displayed to check the results. Intersects may be avoided by, for example, increasing the Offset Value or by using a more accurate Fuzzy Level.

When completed, the Fuzzy Offset feature will appear in the Feature Tree as follows:
