  1. XOR is a mnemonic for "Exclusive Or".  It is a logical operation with the following truth table:

     

    True XOR True = False

    True XOR False = True

    False XOR True = True

    False XOR False = False

     

    True and False can represent On and Off.

    In other words, If both operands are the same, the result is off (invisible in this case).

     

    XOR in other use cases can be used to "flip" the bits in a set: True False True XOR TRUE TRUE TRUE = False True False

    In this case, the second argument TRUE TRUE TRUE means flip all 3 bits.

  2. The issue is that I didn't know which wall to double-click on.

     

    I was working on a plan experimenting with different exterior siding material options, combinations of different stone and stucco types, etc. and creating new wall type definitions to see how they would look.  After deciding which wall type I liked best, I went to clean up my list of wall type definitions.  In the "Wall Type Definitions" dialog, I use the "Delete" button at the top of the dialog to remove wall type definitions I no longer use, and see the message:

     

    "Cannot delete this wall type, it is used by one or more walls in your plan."

     

    I could not tell by the appearance in plan view, or 3D view, which wall had the wrong type, and did not want to open each wall manually to find it.  Changing the fill color identified the wall I was looking for immediately.

     

    Hope that clarifies.

  3. If your Lenovo laptop has an add-on GPU card and also has Lenovo Vantage software installed, you may discover that Preferences->Video Card Status, only shows the graphics processor onboard the CPU, not the add-on NVIDIA graphics card.  The render performance may be very slow.

     

    Solution:  Open Lenovo Vantage and disable "Hybrid Mode".  After a reboot, you'll see the NVIDIA graphics card and your render performance will be much improved.

  4. This is a new construction project.  Due to lot size constraints, I'd like to put a home theater in the basement underneath a 20x20 2-car garage.

    Structural engineering needed for the "ceiling" weight capacity, and waterproofing.

    I don't know how to approach this with Chief.

     

     

     

     

     

  5. I started over and got it to work.  I cannot explain how I originally put the two solids on different levels from the elevation view, but when I did it again, they both ended up on the first floor.  I'm pretty sure that what caused the "make hole" box to be disabled is that the inner solid was slightly overlapping the edge of the surrounding solid.  When I re-positioned the inner solid entirely within, the checkbox became enabled.

  6. Thanks Eric.  I've moved both solids entirely away from the structure.  Even though overlapped, the "Hole in Polyline Solid" checkbox for the small triangle is disabled.  What should I be looking for to determine the levels or surface/depth of the two solids?  Can this be done from within the elevation view?
