What version of VW are you using? Can you post a file with just the DTM?

It sounds like you are doing something like putting =LENGTH(C='This Class') in a cell. If you right click on a row header and choose database you can choose the criteria in the next dialog box. Then in that same row, enter =LENGTH in one of the cells to get the length of each line in that class.

Just tried it in 2017 and got the results you got. It behaves the way you want in 2018. I don't have 2016 on this computer, but I thought that the 2018 behavior was already established in 2015 or 2016.

What version are you using? I think the behavior of height and width rotated rectangles changed in the past couple years.

Agreed. Use whatever you - or someone who likes you well enough to take your panicked phone calls - can fix.

I don't think you'll find a major difference. The important thing is to get a computer that can handle VW well. That means SSD, good graphics cards, lots of RAM, lots of VRAM. etc. i.e., not a cheap computer.

None of the components in that wall have a texture. The only texture is applied to the overall wall itself. It gets confusing quickly.

There are a couple things going on :-) You have the wall set to render by object (rather than by component). And you have the right side set to have Texture-4. The left side of the wall is always the outside. Change the texture setting to the left side and it will behave as expected. OIP > Render Tab > Mode: By Object > Part: Left > Texture: Texture-4 (Go to top plan view. Select a wall. There will be an arrow on one end of the wall. If you were to stand on that arrow facing the same direction, the "left" side of the wall would be on your left. If you always draw your exterior walls going clockwise, you'll get it right.) OR You could set the wall to render by component. Then go into the resource manager, and edit the components to either have a texture or use a class texture. The first component on top of the list is always the left side of the wall. It's confusing at first. Post back if you have more questions.

Peter I totally agree that VW already uses the IES data. The renderings using IES sources make it clear. And I also really wish that data could be used other ways.

Unless it has changed in recent versions the photometric tool used with spotlight instruments doesn't use IES data. It's using photometric data attached to the symbol and straight inverse square law for footcandles calculations and something like an arc tangent(?) to calculate falloff. It's taking advantage of the fact the many/most theatrical fixtures have simple cones defining field and beam angles and the spaces are typically one large volume. If you draw a wall between the theatrical fixture and the photometric grid the result on the photometric grid doesn't change. So it's not something that can easily be ported to Architect.

When I installed 2018 and migrated my workspaces, I let it bring over all my workspaces, including the default workspaces. Do I now have default 2017 workspaces in my 2018 installation? If so, is there a way to download the default 2018 Spotlight, Architect, and Landmark workspaces?

Can you post a file with just the wall and the window?

It's just =AREA

Check this thread out. It has a script that uses the contents of a worksheet to create classes and class descriptions. I'm sure creating one for layers wouldn't be too hard. (famous last words)

Windows consider the left side of the wall to be the outside. Reverse the direction of the wall and the sill will flip around.
