How to make model look faded?

Postby U5tabil » Fri Jul 27, 2018 11:04 am

I am not sure what the proper name for what I want is. But have tried searching under several subjects without luck.

What I want is that the floor plans I work with is a bit grayed out / transparent / opacity / weak.
So that what I draw on top pops more out. By example I will be drawing where pipes for ventilation goes. And I don't want the walls to be so strong. Almost like the model/floor plan lays behind in a way.

What is the proper term for this, and how can I achieve this?

Are you modeling everything in SketchUp? Or are you drawing the ducting in LayOut?

One easy way to do it is to put a layer in between the layer the floorplan is on and the one the ducting is on. Draw a large rectangle on that in between layer and adjust its fill opacity to suit.

I have the floor plan in sketchup, but the plan was to use layout to draw the ducting on top.

How would I do what you recommended? Doing it entirely in sketchup instead then?

In SketchUp, create two scenes. One of the floor plan only and the other of the ducting only. In LayOut, do the same thing as above with three layers. The bottom layer has a viewport showing the floorplan only scene, the middle has the rectangle with reduced opacity, and the top layer has a viewport with the ductwork only scene. Place the floorplan viewport and set its scale as desired, then copy the viewport, make the top layer the active layer and paste to that layer. Change the pasted viewport's scene to the ductwork scene and they will be properly aligned.

If you wanted to do it entirely withing SketchUp, you could edit the materials used in the floorplan to reduce their saturation or you could move the ductwork up above the floorplan and use Fog. I think the method with the two scenes and the rectangle in between is easier.

Thanks but never worked with scenes before, just tested a little but not getting it to work. Mostly my lack of skills, do you have a tutorial somewhere on something similar?

I'd probably opt for the suggestion you made yourself! Drawings the electrial layout over the floor plan, whilst using Dave's recommendation of a semi transparent filled square over the SU view.

Work in three layers so you can turn the transparent layer off whilst snapping to the SU view for your electrical work, turn that layer back on prior to exporting!
