Two options. Import as a reference inside a design layer-referenced viewport and then add a crop object to the viewport. This will also exclude all of the hundreds of classes from your file. If that isn’t an option, then try using the clip tool in the second mode to crop away geometry outside of a rectangle that you create with the tool.

The data in the Truss Record is not dynamic and will never change. However, the weight field in the Truss Object can be updated whenever you like. It's all about choices!

Go to the header cell of the weight column and add a "/1000" to it.

Use the Clip Tool in the second mode. If it is just regular geometry, then you should be fine. If there are lots of plug-ins and symbols, then you should think about using a cropped design layer Viewport.

I hadn't noticed this and have often wondered why it works on some viewports and not others. Well done for finding the correlation. I suspect it's a bug. Can you file a report?

I suspect you have inadvertently made your views relative to a different working plane than the Design Layer Plane. In the View section of the View Bar, make sure that you have View relative to the Layer Plane checked.

If you double-click or right-click on the solid and select Edit Features, then you can select the part of the object you want to edit, and the correct historical level will be accessed in the Solid object's Edit window.

One of two choices. Turn of Layer colors or Black and white only. Both of these settings have buttons in the quick preferences bar.

You need to have Layer Colors enabled. This can be found in the Vectorworks Prefs or in the quick preferences bar.

Weirdly, if you turn on Show Measurement in the Document Units and specify Meters it shows as "m".

You are correct. Sadly, there is no way to change it (that I know of) other than ungrouping the object and then running the lowercase command from the Text Menu with the objects still selected. Please file a bug report!

I had thought of that, but it seemed too much of a hack!

Rigging Load objects will only rotate around the Z-axis. So, you should have no problem moving and rotating the Hanging Position. However, if you roll the hanging Position, the attached load will stay resolutely upright.

Firstly, it's just rigging items and custom geometry that go in hanging positions, not the attached lights (Loads). To un-make a hanging position, just run the Ungroup command. Everything will now be separate again. Come back if you need more. Good luck!

Go to Spotlight Preferences and in the Lighting Device class and color section, activate the Modify Lighting Device Color and then select the first option. This will enable you to change the Lighting Device color based on what is applied in the Attributes Palette. You should also consider Data Visualization, but for now I think this is what you are missing.
