More controlled rebar dimension mark placing

Previously the manual rebar dimension mark creation ignored the defined dimension placing settings and always used free placing, and automatically determined the location of the dimension.

Now, the default value for the Placing setting in Rebar dimension mark properties is fixed in all environments. When you create a rebar dimension mark, you will be asked to pick a location for the dimension line.

You can create rebar dimension marks using the Dimension Mark command on the context menu or the Rebar command on the ribbon.

The Placing setting is considered during manual dimension creation as follows:

If you have selected more than one rebar object, the Dimension Mark command ignores the fixed option and automatically places the rebar dimension mark for each selected rebar object.
If you have selected only one rebar object, and Placing is set to fixed, you will be prompted to pick a position for the dimension.
If you have selected only one rebar object, and Placing is set to free, the dimension will be placed automatically.
With the Rebar command on the ribbon, you can create rebar dimension marks without selecting a rebar object first. In this case, you will be prompted to pick a rebar object:
- If Placing is set to fixed, you will be prompted to pick a position for the dimension, and if Placing is set to free, the dimension will be placed automatically.
- After the dimension has been placed either manually or automatically, you will be prompted to pick another rebar object.

TSAC-4843	Steel components	JP Full depth special (185): Previously, the tab plate was created with incorrect dimensions. This has now been fixed.
TSAC-4927	Steel components	Z pan (S74): Previously, when the length of the front part of the step was specified as zero, the top step was created incorrectly. This has now been fixed.
TSAC-4952	Steel components	Bolted gusset (11): Previously, when the size of the cut created for the gusset plate was zero, two gusset plates were created. This has now been fixed and only plate is created.
TTSD-39164	Steel components	Mirroring single leg rebar groups with different From plane values at the start and end now works for all spacing types.
TTSD-41488	Steel components	You can now use the `XS_USE_OLD_MACRO_INPUT_POINT_VISIBILITY` advanced option to restore the old component input visibility in the rare case where the input points need to be selectable in the model view. Note that the setting only affects new component objects in the model, not the existing components. Add the advanced option to an `.ini` file, as follows: `set XS_USE_OLD_MACRO_INPUT_POINT_VISIBILITY=TRUE`
