Freeze or unfreeze a rebar set

You can freeze rebar sets in the model to prevent automatic adjustments and unwanted changes in them when surrounding objects, such as neighboring rebar sets or the parent concrete part, are modified. Freezing rebar sets is useful, for example, when bars have already been detailed, fabricated, or put in place on site.

When you freeze a rebar set, its automatic, intelligent adjustment behavior is disabled, and it starts to behave similarly to a basic reinforcing bar group with 适应性 set to Off. Freezing affects the 钢筋放置 properties of the rebar set as follows:

自动分层 is set to Off.
Layer number becomes unavailable.
The Offsets settings become available.
适应性 is set to Off.

For each leg face or leg surface in a frozen rebar set, 自动分层 is set to Off, Layer number becomes unavailable, and the current bar leg distance from the leg face is saved as a fixed offset (从肢面到钢筋边缘 or 从肢面到钢筋中心).

A frozen rebar set does not automatically react to modifications in the parent concrete part's geometry, concrete cover values, or other rebar sets. However, you can still manually modify the rebar set properties, or the geometry of guidelines, modifiers, and leg faces. Modifying a leg face of a frozen rebar set, for example, by adding a new corner point, unfreezes that specific leg face. If you add new leg faces to a frozen rebar set, they are also unfrozen. Note that the bars in a frozen rebar set that are at leg surfaces still react to changes in the parent concrete part, because leg surfaces always follow the geometry of the parent part.

If you move, copy, or delete the parent concrete part to which a frozen rebar set is attached, the frozen rebar set will follow.

In model views, frozen rebar sets, leg faces, and leg surfaces are indicated with a snowflake symbol next to the layer number when you select rebar sets and when the leg faces are visible.

When you unfreeze a frozen rebar set, its automatic, intelligent adjustment behavior is enabled again, and the rebar set starts to react again to changes in the surrounding objects.

Freeze a rebar set

On the 钢筋 tab, click 更多 > 冻结.
Select the rebar set that you want to freeze.

To select multiple rebar sets, use area selection.

Alternatively, and to freeze multiple rebar sets at a time, first select one or more rebar sets in the model, and then start the command in one of the following ways:

Click 钢筋 > 更多 > 冻结 on the ribbon.
Right-click, and then select 冻结/取消冻结 > 冻结 from the context menu.

Unfreeze a rebar set

On the 钢筋 tab, click 更多 > 取消冻结.
Select the rebar set that you want to unfreeze.

To select multiple rebar sets, use area selection.

Alternatively, and to unfreeze multiple rebar sets at a time, first select one or more rebar sets in the model, and then start the command in one of the following ways:

Click 钢筋 > 更多 > 取消冻结 on the ribbon.
Right-click, and then select 冻结/取消冻结 > 取消冻结 from the context menu.

Unfreezing affects the 钢筋放置 properties of the rebar set as follows:

自动分层 is set to On.
Layer number is set to Auto.
The Offsets settings become unavailable. The offset values revert to Auto if they were set to Auto when the rebar set was frozen and have not been manually adjusted since freezing. If manual values were used before or after freezing, they are preserved.
适应性 is set to Default (=the model's Default adaptivity option selected in the Options dialog).

For each leg face or leg surface in the unfrozen rebar set, the previously stored distance values are deleted. The location of the bar legs is then recalculated based on the current concrete cover values and layering information.
