Asta Powerproject 2026.2 release notes

This issue has now been addressed. If the project from which you are trying to export data includes a formula that refers to a non-existent code, rather than this causing the formula compiler to fail, the result from the non-existent code is now treated as 'null' - meaning that no such codes are assigned - which allows the formula compiler to work.

If you open a 3D model in which imperial units of measurement are used in Asta Powerproject 4D, the calculated area and calculated volume values are now displayed using imperial units, rather than being converted into metric units.

You can now create a project schedule automatically from one or more 3D models, or from one or more IFC group models. This provides you with a quick and easy way of constructing a schedule, based on the properties of the 3D models themselves, and is particularly useful if you are starting a new project with one or more 3D models that contain a substantial amount of information from the outset that is relevant to the schedule.

When you create a project schedule automatically from one or more 3D models, you specify the properties within the 3D models on which you want to base the project hierarchy. For example, you could base the hierarchy on the 'Site', 'Building' and 'BuildingStorey' properties. If you did this, the resulting hierarchy would have three levels: one for each of the selected properties. The top two levels would be represented by summary tasks, while the lowest level would be represented by individual tasks, which would be associated with the 3D objects in the 3D models using IFC product searches which are created by the wizard.

At the same time as creating the project hierarchy, you can choose to create one or more code libraries, containing code library entries that correspond to the values contained within specific 3D model properties. If you choose to do this, the code library entries are assigned to the relevant tasks at the lowest level of the hierarchy. The creation of code libraries is optional, but it does provide you with a powerful way of making the most of the data that is contained within your 3D models.

This release of Asta Powerproject introduces a number of 4D-related improvements to the Ribbon, which make it easier to work with your 3D models in Asta Powerproject 4D.

The following improvements have been made to the 4D tab of the Ribbon:

• The Configuration control has been renamed to 'Manage Models'.
• A new 'Project' group of controls has been added, comprising controls that you can use to create a project schedule automatically from one or more 3D models; to reschedule your project; and to open Library Explorer. The latter two controls are duplicates of commonly-used controls that exist elsewhere; they have been added to the 4D Ribbon tab to save you from having to switch from tab to tab so frequently as you work with your 3D models.
• The drop-down control that you used to use to display and hide various elements of the user interface including the IFC Model pane, the IFC Properties pane and the IFC Comparison Model pane, has been replaced by a series of controls in a new 'Panes' group, which you can use to toggle different elements of the user interface on and off. This means that these controls are easier to locate and more convenient to use.

In addition to this, when either the IFC Model pane or the IFC Comparison Model pane is in focus, the Format tab of the Ribbon now displays a selection of controls that you can use to work with the 3D model. Some of these controls used to appear on the 4D tab, but other controls - those relating to splitting and merging 3D objects - were previously available only via right-click menus. Duplicating these controls on the Format tab makes them easier to locate and use.

A tick now appears next to the last-chosen selection in the Hide/Show Items dropdown, indicating which option is currently selected.

As the visibility of items can be adjusted manually, the last-chosen selection is cleared - and the tick disappears - when any of the following actions are taken:

• The 3D model is reset.
• A 3D object is hidden manually.
• IFC product searches or selections are shown or hidden, via the project view right-click menu.
• A timeline simulation is run.
• Unassigned or unscheduled tasks are shown.
• The 3D model is changed.

Along with a number of other controls, the Hide/Show Items dropdown has now been moved from the 4D tab of the Ribbon to the Format tab.

The 'IFC product count' field previously relied upon a 3D model - or an IFC group model - being open in order to be populated correctly with information from the model. If a project was opened without its 3D model being opened too, this field displayed incorrect information.

If the 'IFC product count' field is present in any of a project's initial views when the project is opened without its 3D model being opened too, it now displays information about the 3D model that you last had open. Provided the project you last had open was the same as the project you have just reopened, this means that the 'IFC product count' field now displays the correct information.

If you add the 'IFC product count' field to the spreadsheet when a project's 3D model is not currently open, or if you display a view in which this field is included after a project has been opened without its 3D model, the information displayed in the field may not be reliable; in this case, you should close and re-open the project in order to refresh the field with data from the 3D model that you last had open.

While addressing this issue, a number of other issues that affected projects that were opened without their 3D models being opened too were identified. To address these issues, the following improvements have been made to Asta Powerproject 4D when a project is opened without its 3D model being opened too:

• Previously, if an IFC product selection was associated with an IFC group model rather than with an individual 3D model, no information about the relevant 3D objects were displayed in a project if it was opened without its IFC group model being opened too. Information about IFC group models is now displayed correctly in projects that are opened without their IFC group models being opened too.
• It can take some time for Asta Powerproject 4D to connect to an IFC group model to access information to display in a field when the IFC group model is not currently open. A progress indicator now appears when Asta Powerproject 4D is connecting to an IFC group model for information that it needs to populate a field, which makes it clear that Asta Powerproject 4D is doing something, and has not stopped responding.
• If no 3D model is specified against an IFC product search, it operates on whichever 3D model or IFC group model is currently open. If no 3D model is currently open, such IFC product searches previously displayed no information about 3D objects. If no 3D model is currently open, IFC product searches for which no 3D model has been specified now display information about the 3D model that you last had open.
• Previously, Asta Powerproject 4D was unable to identify that a 3D object had been split or merged unless the 3D model was open. Information about split and merged 3D objects is now displayed correctly when a project is opened without its 3D model being opened too.
• Improvements have been made to the way in which information about the 3D objects that are grouped together by IFC product searches and IFC product selections is loaded into Asta Powerproject 4D. This means that if you open a project, close it and reopen it within a single Asta Powerproject 4D session, reopening the project now takes less time, as the 3D object data no longer needs to be loaded a second time.
• Previously, errors could occur if you previewed a view for printing in which the 'IFC product count' field was displayed in the spreadsheet. These errors no longer occur.
• Previously, if you closed a project that had an open IFC group model, the cache of data about the IFC group model's 3D objects was retained. This caused issues if you subsequently re-opened a different project without its 3D model, as Asta Powerproject 4D used the cache from the IFC group model that had been open to populate fields. Now, when you close a project that has an open IFC group model, the cache of data about its 3D models is cleared. This ensures that when you reopen a project, Asta Powerproject 4D uses the correct 3D model or IFC group model to populate fields.

Note that site objects are excluded from IFC product searches when a project is opened without its 3D model being opened too.

Asta Powerproject was failing to assign an original start date to the start milestone in this situation, due to the original task having no assigned calendar. Milestones are now assigned an original start date when they are created from tasks with no assigned calendar, meaning that it is now possible to save projects in this situation.

Task work-based histograms no longer ignore task work for completed milestones when they are configured to include all tasks, regardless of progress.

Changing the calendar of a task in the above circumstances now results in the task retaining its original duration in terms of days, rather than being given the duration of the modelled resource allocation.

Note that this change does depend on the modelling type of the resource allocation, and that if the allocation's modelling type cannot be changed, the original behaviour will persist.

This issue has been addressed, so the 3D model is now displayed correctly when it is opened in Asta Powerproject 4D.

Asta Powerproject version 2026.1 introduced the ability to copy and paste lists of codes, consumable resources, permanent resources and users into Library Explorer, to speed up the process of setting up new projects in situations where a list of these items is available in another application.

You can now also copy and paste lists of cost centres into Library Explorer.

You can copy and paste lists from a variety of applications. For example, you can copy lists in which each item is separated by a 'carriage return' from text editors such as Microsoft Notepad or Microsoft Word; and you can copy lists in which each item comprises an individual cell in a spreadsheet column from spreadsheet editors such as Microsoft Excel.

Asta Enterprise has been enhanced so that this problem no longer occurs.

More information on opening projects

A prompt now appears after you have created a new Asta Vision project from within Asta Powerproject, giving you the choice of checking out the project's initial programme or displaying the list of Asta Vision programmes on the Open tab of the Backstage view, from where you can download the programme, check out the programme, or start a collaboration session on the programme.

Investigation showed that this issue affected WBS-related fields as well as Task ID (WBN)-related fields. The data in these fields should have appeared as read-only in Project Viewer, rather than not appearing at all. Data in WBS-related fields and Task ID (WBN)-related fields now appears correctly in Project Viewer

This was caused by Asta Powerproject calculating the task work on the tasks that resulted from the split based on the total task work, rather than on the actual and remaining task work. Asta Powerproject now calculates task work on the resulting tasks correctly when a task is split, which means that such tasks retain the correct total duration.

More information on splitting and merging tasks and allocations

This was caused by early sections of the project being completed, and selection tracking and bar chart tracking not working for completed sections of tasks. Selection tracking and bar chart tracking now work for completed sections of tasks.
