it's a photorender using only a part of the model.

either use the marquee or the '3D Cutting Planes...' to form the cuts through the building that you require. then set up your camera, lights, etc and render away!

the material of the cut line itself can be defined separately - and over-ride the element's own material - from within the '3D Cutting Planes...' dialogue.

here's one i made earlier. it's only a WIP of a series of renderings that got abandoned. in addition to the technique you described originally, i was trying to wireframe the portion of the building behind the cut line as well.

it got too messy quite frankly.

I have never tried this before but after seeing your rendering with the cut plane and wire frame, I am quite interested in it.

Was this all done in Archicad with one rendering. Or is it two seperate rederings, one for the sectional cut plane, and one for the wire frame, then overlayed using photoshop?

A little help on how you went about his particular creation would be greatly appreciated.

Quite simple.

You can also do it with a fat marquee if the cut is vertical. If it is not, use cutplanes instead of the fat marquee.

Place the fat marquee, and rendering parameters, save the view. Output in photorendering window.

Move the fat marquee so that it covers the rest, change the 3D to wireframe, internal engine, save the view.

Place and overlap the views in the layout (PlotMaker for those still on 9).

Make sure that the top view (wireframe) has transparent background.

Size is not the problem, because the wireframe is a vectorial view that you can resize exactly to the rendered image.

You can also play with the wireframe status of layers; I recently did a project where the inside was the point, the outside was only to keep the sun and the dust out; so it worked QUITE well.

this particular image was composited in photoshop because i needed to control the opacity of the overlaid wireframe. unfortunately it didn't work out: too much opacity and it became too messy, too little and you can barely see the wireframe. there didn't seem to be a happy medium.

djordje's method covers the basics. it's easy to do. it all boils down to whether or not the story you need your image to convey will be helped by this type of presentation . . .

let us see the results if you get anything you like!

good luck

The photoshop composite method requires erasing a lot of the wireframe - to avoid messy conflicts - and carefully selecting a complimentary color for the wireframe.

Certainly will! I'm finishing up my Thesis design project now. I'm doing a Skateboarding park that blends into a support building which will house cafe/hostel/pro shop/work shop/etc. I will be using this to show a cut in the building while still showing the skateboarding elements (bowls, ramps, stairs, rails, etc.) that blend into it and around it.

Thanks for the help from all!

i used cutting planes: firstly in one direction, and then again in the other direction, (keeping the 3D window size the same for each), so that i had half a model in wireframe and half fully rendered.

we'll look forward to it then!
