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:
