When you place spot elevations on your floor plan, if you try and place them on ramps you will notice that this isn't possible using the spot elevation tool.
It is possible to place them on elevations and section but plans it isn't possible......or is it?
A simple work around is to place the spot elevation onto a floor and then move or copy it onto the ramp and magically it will host itself to the ramp levels.

Voids can be a very useful object in complex form modelling. If you need to create a complex structural form you can use the edges of the void as a path to help host sweeps. As the void is negative space it won’t be visible in the final model.
It is a lot easier to create paths on the edges of a void form rather than having to try and create the path as a line. This is evident when you have to distort the path in 3 directions, (It is possible to do it using an adaptive family with points and splines, but is just so much simpler to use a void).
In the example I am using an extruded blend to create my void form.
Once you have the edges looking correct, just host a sweep to the edges using the ‘Pick Path’ and your complex form is finished.

A very effective way of rendering your design model is to assign a balsa wood material (or white card material) to all elements. Instead of having to engage in a time consuming process of saving a design model and reassigning materials, there is a very quick and easy process to gain the desired result.

When you are using the Dimension tool in your model, sometimes the dimension text will be placed where it overlaps with the dimension line or ‘Tick’ mark. It is easy enough to move the dimension text away by selecting the blue dot at the bottom of the dimension text.
The result will leave you with a leader line back to the middle of the dimension line. If you want to remove it from the Dimension string, just look at the Options Bar and untick the ‘Leader’ tick box. This will remove it from the entire dimension string.
Unfortunately, the leader is turned on by default in all dimensions. If you want to turn it off in all the dimensions in your project you can select any dimension string and right-click, this will bring up the option to ‘Select All Instances’ > ‘In Entire Project’. Then you can turn off the leaders to all dimensions of that type.

If you need to export your Revit model to CAD for any reason you need to be careful what scale the Revit view is set to prior to exporting. At different scales you will get varying results in the final CAD file.
For smaller scales the export is without problem, but for some larger scales (above 1:200) the export will start to drop detail in you CAD file. And there doesn’t seem to be any logic towards what goes missing.
The examples below are images of the final AutoCAD (DWG) exports for a simple screen model.
Original Revit Model
Revit Export Scale 1:200
Revit Export Scale 1:500
Revit Export Scale 1:1000
Revit Export Scale 1:2000
So when you are exporting to CAD from Revit, be aware that any exports above 1:200 may not give you the results you were expecting.

If you are working with In-Place Masses be careful when you group them together. The masses will group together fine, it is only when you try to move or copy the In-Place Mass Group that you will start to encounter some problems.
When a group containing In-Place Masses is moved or copied they will not relocate to their new position. Instead they will remain in their original location creating a duplicate copy on the same instance, (or worse….. and start randomly placing masses).
This is clearly evident when you have modeled elements grouped with the masses (eg. Floors), the modeled elements will relocate properly and the masses are left behind.
So when you are working with In-Place Masses, try not to group them together.
