Rerouted Dimensional relations

It’s very common to make relations while modeling, both from geometric references and dimensional formulas. When these relations get damaged, the feature holding it will not fail. They are said to be rerouted. Features with geometric reroutes are marked in the tree with a special symbol, but up until Cimatron 2026 there has been no symbol for dimensional reroutes.

Now any feature holding a dimension that includes a damaged formula or setup link will also be marked.

• The new symbol is the same as the familiar “broken” geometric reroute, but with an additional red 𝑓.

• A feature with both geometric and dimensional reroutes uses a broken symbol with a yellow background.

In this feature tree Sketcher17 has a rerouted geometric reference, Extrude22 has a rerouted dimensional
expression, and Sketcher 21 has both geometric and dimensional reroutes in it.

Highlighting rerouted dimensions in features

In earlier versions, the only way to see if a dimension had a damaged expression or setup link was to click on it. Inside the expression box, the problem link would be highlighted in red, rather than the normal yellow.

For Cimatron 2026 the entire dimension is now shown in red. This lets you know immediately which dimensions have a reroute issue and may no longer be functioning parametrically as intended.

The dimension in this sketch with the rerouted dimensional expression is obvious due to the red highlighting.

Rerouted dimensional relations in feature parameters will also be shown in red, rather than the usual purple color.

Searching for rerouted features

An additional feature tree search has been added in Cimatron 2026. It is for features that have been rerouted. Rerouted features are those that have a missing parent reference and may no longer be fully associative.

• In the assembly tree, an example of a rerouted feature would be a Connect that has lost a geometry reference.

• The assembly tree also uses the same reroute symbol for parts that are no longer found in the folder.

• In a part tree, a rerouted feature may be missing a geometrical or dimensional reference.

Like the other tree searches, a count of the affected parts is provided and the affected rows are highlighted yellow.

A search for reroutes in the assembly tree may find rerouted features or missing parts.

A search for reroutes in a part tree may find features damaged by missing geometry or dimension references.

Feature Reference Management

Large and complex parts may hold many features with external references, and navigating those references might prove a bit difficult. Cimatron has an existing tool (Relation Analyzer) which can help us see the relations of a single feature. However, that does not give us the full picture for the entire part.

Cimatron 2026 offers a new tree tab on the part tree dedicated to references called Reference Manager (Ref Mgr). The new tab shows a global view of all rerouted references in the part. It provides a comprehensive view of all lost references along with some detailed information.

The tree has 3 columns:

• The feature name and the type of reroute it has.
• The internal or external feature that provided the lost reference.
• The specific detail that provided the lost reference, if known.

The Reference Manager tab exposes information on feature associativity. If you need to repair or replace a lost reference, understanding more about what has gone missing will help. The actual process of replacing a lost reference still requires you to edit the feature. This has not been changed.

Note that the new tab is only visible in parts where rerouted references exist.

Visibility of this new tab is controlled by the Preference under General > Reference Manager.

The tree tab for Reference Manager will be shown in any part where rerouted features exist.
To disregard this extra information, unmark the general preference checkbox.

The reference manager tree tab only shows features in the part that are rerouted. When possible, the details of the lost reference are given.

Recently used fonts

Any Cimatron function that creates text, in Modeling or Drafting, can use any font from the standard Windows fonts folder. Because this folder may have hundreds of fonts in it, finding the one you want from the list is time consuming. To make things easier, in Cimatron 2026 you will see that your 5 last used font styles are always kept at the top of the list, where they are easy to see and select again.

There are actually 2 lists for recently used fonts. One for modeling text and other modeling functions, and a separate list for Drafting and PMI tools.

The font lists are not file specific, so the most commonly used fonts will always be seen in any new file going forward.

3D text functions like Wireframe Text and Volume text keep the 5 most recently used font at the top of the font list.

Drafting function like Text and Dimensions keep the 5 most recently used font at the top of the font list.

New preference for Text sizes

Any Cimatron function that creates text in Modeling, Drafting or NC needs a convenient list of text sizes that suit your needs. Preferred Text Heights is a new general system preference page where 10 values (for both inch and mm) can be stored. These sizes will be available throughout the system, from modeling to drafting and NC. Having a custom size list means not having to settle for system defaults and less typing in many functions.

Per the drafting preferences, each type of drafting symbol can have a default text height. This is independent of the 10 preferred sizes and can still be set to any value you choose.

Preferred Text heights is a new general preference page.

The text list in any modeling function comes from the new preference page.

The drafting character height list references the same preference page.

Highlighting max gaps in Fillet

Fillet is a long established and useful surfacing function. A criteria for each set of faces that contribute to the fillet is that they all form an edge to edge continuous strip within a small, adjustable max gap tolerance value. If a larger gap is found, the system will show an alert. The warning is good, but very often a large number of faces are selected, and the gap area can be difficult to see. Cimatron 2026 now visually indicates each area in the group of faces that exceeds the max gap tolerance.

v2025 could alert a user that the max ga value was exceeded, but not where the gap actually was.

In v2026, a yellow highlight will appear at the areas that exceed the fillet tolerance.

Loft twist control

The Loft function usually aligns all of the chosen contours in an automated way. While that logic is normally fine, occasionally an example would be encountered where the Loft shape would appear twisted. For such cases a new optional step called Align Contours has been added that offers manual control.

• Contour start points can be manually indicated at any endpoint.

• Contour directions can be flipped by selecting the arrow.

In earlier versions, rare examples would exhibit twist.

In Cimatron 2026, problem examples can be adjusted for contour direction and start point.

Extra pipe thread depths

The depth of pipes in the Pipe function can be set as a factor of the diameter (when using the By Screw Size option). Cimatron 2026 now offers four factors for tapered thread types G, R, and NPT:

• 0.5x, 0.75x, 1x, and 1.5x

Depth control of tapered pipe threads is set by a diameter factor.

Extend both ends of curve

In the wireframe Extend function, a new option allows both ends of the curve to be extended at once with the new ‘Both Sides’ option.

Note that when using Both Sides, you cannot extend the curve to a reference, only by Delta.

Extend can be set for ‘Both Sides’ of the selected curve.

Preserve formulas when updating a catalog based part

On occasion, a Cimatron catalog file will be updated, either with new geometry, attributes, or table values. When this happens, components in existing jobs that are based on this catalog will be able to update. This is generally desirable to ensure the component represents to the latest shape and size data. It is not desirable if it will damage the parametric knowledge built into the assembly. Care has been taken in Cimatron 2026 to avoid such problems.

• Updating any catalog based part is much like remaking the part, but now the update process will first record all formulas found in the part and then re-apply them on the updated part.

• This is true of formulas made from a part dimension or from the setup table.

A shoulder bushing has a dimensional formula to another part, but the source catalog has been changed. The part requests an update

After update, the formula remains valid and linked to its source part and parameter.
