TSAC-4271 Concrete components

Floor layout: When picking points to create the floor layout, Floor layout now uses the work plane instead of the view plane, when the work plane is set.

TSAC-4449 Concrete components

Geometry detailing strip: The plane position and offset are now properly handled in Geometry detailing strip when the strip is applied on the face of a single part. Previously, the plane position and offset were handled properly only when applied on a wall layout or some other component.

TSAC-4498, TSAC-3588 Concrete components

Wall layout: Opening offsets are now used when the opening is part of the element outline. Note that if you want to have the door step in only one layer and not in all layers, you need to add the door opening with the door step, remove the door step from the other layers by offsetting, and make the opening large enough to cut the door step off.

TSAC-4651 Concrete components

Geometry detailing strip: Previously, Geometry detailing strip detected faces without taking the cut part into consideration. As a result, when a cut part of the geometry detailing strip clashed with another cut part of a geometry detailing strip, the instance created last was not fully created. This issue has now been fixed.

Floor layout: Property strips were occasionally created far away from the picked points. This issue has now been fixed.

TSAC-6458 Concrete components

Floor layout: Previously, floor layout property strips did not work if they were so short that they were completely inside one slab and Hit slab only was selected in Effect in layout. This issue has now been fixed.

TSAC-556 Steel components

Cap plate detail: The default values of convex arc chamfers in a cap plate used for RHS and SHS profile types have been updated. The default values are no longer hardcoded. 
Now, if you define the width and the height of a cap plate, the chamfer radius value of the profile is used. If the profile chamfer radius is equal or smaller than 5 mm, then 0 mm value is applied. If you define the cap plate edge distances, an absolute value of the difference between the profile chamfer radius and the highest value of all edge distances is used.

TSAC-5650 Steel components

TSAC-6442 Import, export, interoperability (concrete)

Export ELiPLAN file (68): Exporting hollowcore with an unusually high amount of complex cuts caused the export to crash. This issue has now been fixed.

TSAC-6454 Import, export, interoperability (concrete)

Export ELiPLAN file (68): In some cases, when exporting a narrow hollowcore, the export interpreted the cast unit as a type beam and not as a type slab, which led to incorrect results. This issue has now been fixed.

TSAC-6471 Import, export, interoperability (concrete)

Export ELiPLAN file (68): Information about the export progress is now shown in a command prompt window.
