Connect walls with joints

When we drew the walls, we did not pay any attention to the corners of the building. This was by purpose so that we can use the feature 'Connect wall' to correctt them. 

Go to IMPACT - Elements - Connect wall. 

In the external reference, each corner and connection between elements refer to which joint to use. We can start with the lower left corner. Here, we will use the joint 'AD6-803' to connect the walls. 

Figure 1. Find joint definitions in the external reference.

To add the joint, select both sandwich walls and end with 'Finish'. 

Navigate the to project level and find the joint 'AD6-803'. 

Figure 2. Select joint.

Joints that are not symmetric have more than one option for how it is applied. Check the external reference and select the option there the horizontal wall is extended. 

Figure 3. Different options for the joint.

When the correct joint and option are specified, click 'OK'. A new dialog will appear. It is the Cast-in Material configuration of the joint definition. Here, you have the possibility to edit what Cast-in Materials will be added. In this case, just click 'OK'.

Now, the joint is applied and the corner is fixed. The command is still running with the setup for 'AD6-803' so you can apply the same joint on the other corners. To continue, select two new walls and then select which option you want to use in that case (Case 122078). Finish with 'OK' and continue. When all 'AD6-803' are added, end the command with 'ESC'. 

We have now connected the outer corners. You can continue with connecting the other corners where joints 'AD6-801', 'AD6-802', and 'AD6-805' are used. Note that 'AD6-802' and 'AD6-805' are three-way connections where two sandwich walls and one solid wall are connected. You connect them the same way, just remember to select both the sandwich walls and the solid wall. 

There is also a straight joint called 'AD6-804'. This works a bit differently since the position of the joint cannot be determined in the same way as for a corner.

Go to IMPACT - Elements - Connect wall.

Zoom in on the sandwich walls on the east side of the building. 

Figure 5. Find joint 'AD6-804'.

Select both sandwich walls and end with 'Finish'.

Navigate the to project level and find the joint 'AD6-804'.

Figure 6. Select joint.

There is only one option for this joint since it is symmetric. Click 'OK' for both this dialog and the dialog for the Cast-in Material configuration. 

The last thing you need to do is to specify the insertion point of the joint. In our case, we already have the split for the walls. Select the middle of the split as insertion point. 

Figure 7. Select insertion point.

Now, all sandwich walls are connected. Continue with connecting the solid walls in the same way as we did for the sandwich. You'll find which joints to use in the external reference. 

When that is finished, we will continue with adding doors and windows to the elements.
