There are many differences between experiments with 2D images and ordinary experience in natural, immersive three-dimensional (3D) environments, even when those images are taken from realistic scenes (Chrastil & Warren, 2012; Hayhoe & Rothkopf, 2011). Conventional paradigms often entail very brief exposures to a large number of images that are usually scaled to fit the display. As a consequence, the nature of such exposure substantially differs from daily visual experience, where we are immersed in a relatively small number of environments for longer durations. Spatial learning in 3D environments is also more active in several aspects: For example, movement is self-initiated and accompanied by proprioceptive and vestibular feedback; subjects make active decisions and allocate attention based on the constraints of the task and the structure of the environment (Chrastil & Warren, 2012). These components of active behavior are rarely possible in experiments that attempt to understand scene learning and visual search using two-dimensional (2D) stimuli. In addition, whole-body motion in 3D environments enables the parallel development of both dynamic egocentric (observer-centered relationships between objects and human observer) and allocentric (world-centered representations of object-object relations) representations of the environment. In 2D settings, however, dynamic egocentric representations are not possible (Burgess, 2006; Farrell & Robertson, 1998; Mou, McNamara, Valiquette, & Rump, 2004; Waller & Hodgson, 2006).
Task structure in the real world is also rarely similar to that captured in traditional 2D static paradigms. In this respect, accumulating evidence has shown the strong impact of task goals on attentional deployment. In the context of natural behavior, fixations are directed almost exclusively to regions relevant to behavioral goals (Castelhano, Mack, & Henderson, 2009; Hayhoe, Shrivastava, Mruczek, & Pelz, 2003; Jovancevic-Misic et al., 2006; Land, 2004; Rothkopf, Ballard, & Hayhoe, 2007). The intimate connection between task demands and gaze implies that task may determine the specific information that is attended and encoded in memory. However, there is still ongoing debate on this issue. Võ and Wolfe (2012) demonstrated performance improvement through repeated search for the same sets of targets, suggesting that spatial information encoded during task-relevant experience leads to a benefit relative to semantic guidance. On the other hand, a number of findings suggest that fixated objects are encoded in memory even when they are irrelevant to the current task (Castelhano & Henderson, 2005; Hollingworth, 2012; Williams et al., 2005). These two views may not be inconsistent, as task may prioritize the selection of information to be incorporated into memory, whereas task-irrelevant objects may also be encoded, although with reduced probability (Tatler & Tatler, 2013). Still, how task and memory interact to modulate deployment of attention during ongoing behavior remains unresolved.

Incidental fixations do not always facilitate search. Distributions of search fixations in the correct room when no incidental fixations were made or when at least one incidental fixation was made prior to search trials in (A) 3D experiment and (B) 2D experiment. Graphs on top show the original distributions and graphs on the bottom show the cumulative probability distributions of search fixations. In (A) and (B), probabilities or cumulative probabilities for making more than 30 search fixations were not shown so that the difference between the distributions could be seen easily. (C) Number of search fixations as a function of number of incidental fixations made in 3D experiment. (D) Same as (C) but for 2D experiment.
The other major difference was the large number of fixations in the incorrect room in 3D for the first few trials. Subjects may have been reluctant to exit the room until they were sure the target was not there, because of the big cost of changing rooms. As discussed above, this might point to one of the important characteristics of experience in the 3D environments: The overhead of moving the body from one room to the other, compared with the ease of looking from one room to another in the 2D experiment, may lead to very different strategies. In 3D, search involves full-body motion whereas only eye movements are allowed in our 2D task. The greater probability of choosing the correct room in 3D is also consistent with the adoption of different strategies.
As of Version 2023 the Settings: Connection numbering dialog extends the Display tab with the check box Use default. With this check box you specify that the connection designations of the automatically placed connection definition points are formatted in the same way as manually inserted ones. In the past the "Default value (connection)" property arrangement was always assigned to the automatically placed connection definition points in this case. Now the property arrangement is assigned to the connection definition points that you have specified as the default for the used symbol variant of the connection definition point (for example, in the dialog Save property arrangement). This way it is now possible to format manually inserted and automatically placed connection definition points uniformly with a user-defined property arrangement.
Under certain circumstances, navigation through the tree view was slowed down considerably, in particular if there was a very high number of parts and parallel entries of parts in several tree structures. This has been corrected.
During this search only the most important part properties are now considered by default, such as part number, type number, manufacturer, etc. If you enter a "p" before the search term (for example p:motor), the search is again carried out for all properties. In this case, however, the search takes longer.
In the past the XML import of externally edited parts data with user-defined properties only functioned when the user-defined properties were already previously assigned to a part. It was not possible to use the import to assign user-defined properties of another part (for example by changing the part number in external editing). Now during an XML import of externally edited parts data the user-defined properties are automatically assigned to the parts to which they are assigned in the import file. Through this change it is now possible to transfer old, free properties in the external editing into user-defined properties and then import them again.
When numbering pages in the dialog Number pages: Preview of result in the Target table, the table cells that would change in contrast to the original when numbering are now highlighted with a yellow background. This affects both the page names as well as the structure identifiers.
Since Version 2022 the following network properties can only be edited at bus ports: Physical network: Bus ID / item number (ID 20311), Physical network: Bus ID / item number 2 (ID 20386), Physical network: Name (ID 20413), Subnet mask (ID 20446), Bus system (ID 20308). These properties were initially still available at PLC boxes and were there displayed grayed out. As of this version the network properties at the PLC boxes are not displayed anymore.
The Settings: Connection numbering dialog has been extended with a filter for the potential type for this version. In addition, you now have the possibility to format the automatically placed connection definition points in accordance with the default property arrangement for manually inserted connection definition points. (A possible command path to this dialog is: File > Settings > Projects > "Project name" > Connections > Connection numbering.)
The action partsmanagementapi has been extended with the two parameters PROPERTYIDn and PROPERTYVALUEn so that you can filter the parts to be exported according to the values of the part properties. By specifying the parameters multiple times, all parts are exported for which the properties specified via the property numbers contain the specified values (for example /PROPERTYID1:22007 /PROPERTYVALUE1:, /PROPERTYID2:22007 /PROPERTYVALUE2:).
When numbering conduit packages the conduit definition was numbered correctly, but the associated hose lines retained the original numbering if the device tags were not unique before numbering. This has been corrected.
For parts that were entered with a number of units greater than 1 at the planning object in the pre-planning and that were also assigned to the associated main functions in the detailed planning, the incorrect quantities were output under specific conditions in part assemblies such as parts list, summarized parts list, etc. This has been corrected.
When using a filter scheme for the numbering of devices it was determined that the auxiliary function of a cable was numbered even though the filter scheme should have actually prevented this. The cause for this was the connection definition points of the cable that were taken into consideration as main functions during numbering. In the future, connection definition points that have a superior object (cable, conduit, etc.) are no longer handled separately when numbering, but the numbering depends on the superior object.
During the import of externally edited parts data by means of the action XMImportDCArticleDataAction, a dialog with the number of added parts was previously shown until the action was completed. This dialog can now be suppressed by setting the new, optional parameter SHOWIMPORTMESSAGES to the value "0".
Depending on the numbering format selected for the functions of a macro, the visible device tag of a contact was displayed or not. This has been corrected. The calculation of the displayed DT has been optimized in such a way that the structure in the numbering format of the macro no longer plays any role.
A placeholder object with a high number of value sets could not be opened. This has been corrected. Because of changed basic technologies we recommend distributing placeholder objects with a high number of value sets (> 1000) on several placeholder objects. 2ff7e9595c
