Coverage Cones not showing
My problem is in painting the conic 3-6-9 dB loudspeaker coverage patterns on the seating area. I get the magenta line indicating the aiming angle, but I am not able to turn on the patterns even though the program says the beam patterns are on.
If the Options are shoing 3,6,9 dB Cones ON and the magenta line is visible, check also the currently used frequency under Options, maybe the current band is not valid. Otherwise you should also check if there are really cones with values different from 0° and 180° using the Speakerbase.
Adding Loudspeaker Data Files to the Database
What is the recommended way to add or change a manufacturer's loudspeakers and get into the base. I have the data files on disk but I am unsure how to load them into the manufacturer's data base without interfering the existing data?
Deleting many Listener Seats
When you overpopulate a room with too many listener's seats, is there a way you can globally delete all seats in one easy command?
Go to the Listener Seat Tables (Ctrl+Shift+S) and select the seats you want to delete by dragging the mouse down the left most column. Then go to Edit/Delete Listener Seats. This would waste all the selected seats.
Of course this would work for other items, too.
Activating Items in Project Data
After I activated a loudspeaker in the project data module nothing happens. What did I wrong?
There are two ways to activate items for use:
Invisible Items - How to get them back?
I opened a Vertex property sheet and checkmarked "Invisible". Afterwards the Vertex isn't rendered anymore, so far so good. But now I want the Vertex to appear again, but I can't pick it. How can I get it back?
There are a fistful of possibilities to solve this problem:
Invisible Items are still visible
I opened a Vertex property sheet and checkmarked "Invisible". The problem is, that the Vertex is rendered the same way like before, nothing changed. Is this a programming bug?
Only one checkmark can cause a behaviour like this. In the Options Window/Items Tab (Shortcut: F9) please change (LMB click) the column "Inv." (for invisible items) in the row "Vertices" from "Yes" to "No". This will cause all Vertices which are set invisible not to be rendered.
Displace not working?
I inserted a vertex P1 at (0,0,0), then I duplicated it and I chose for the displacement of the new P2 x=+3. It did not move, why?
EASE 3.0 Only: Make sure that Room Symmetry is turned off or (if it is turned on) that the Symmetry Axis is not at x=0, otherwise a displacement moving the Vertex off the axis (in x-direction) is not allowed.
What does the message "Non-Zero Surface Integral" mean and how do I solve this problem?
After the command Check Data has been invoked, EASE calculates the sum of all faces areas. This sum can be considered as a three-dimensional value because every area is added dependent on its orientation in the room. For example two parallel faces with equal areas looking at each other would give zero.
As a result the surface integral of a closed room must also equal zero with a little tolerance.
To solve this problem: In most cases there are two or more faces in the same location. Delete one of them.
Does a coat face change the RT of a room or can it only serve for presentation purposes (like edges)?
A coat face is a face that replaces (acoustically) the covered part of the face it is assigned to.
That means:
Slow Project Data Module
I have finished now a project with approximately 300 Faces and 40 Loudspeakers. But anytime I change something the Project Data Window takes several seconds up to a minute to update the view. Is this a bug?
No, propably not. There are two main reasons for the editing module slowing down that dramatically.
