Line Types in section/elevation drawings.

[toofuerte]

I am trying to create a elevation drawing and to make the foundation and basement dashed lines in the elevation but I change the line types for the walls and elements and they do not change. I have tried looking for other options for changing these line types but haven't found any if you can help that would be great.

You can't modify the 3D linetype.

A technique I have used is placing a fill over the elements I want dashed.

Set up a pen to be white and very wide. Create a fill based on a diagonal line pattern. The lines in the pattern will mask the elements behind, while the spaces are transparent. (Make sure the background pen is zero.) Experiment with the weight of the pen and the spacing of the fill to get the effect you want.

Almost 14 years later and this worked like a charm.

Thank you internet stranger!

Beautiful workaround, hitherto unbeknownst to this user. There is no tandem workaround for getting rid of the shadows below ground level, and one must forget about shadows above grade when also showing below-grade, right?

[Other than making two elevation drawings with different settings, from duplicate markers in order to check-uncheck shadows, and joining them in the layout. A bit too much.]

If there is none: I wish there were masking fills, to overlay and modify the colors below adding-subtracting-multiplying-etc. colors.

Could you just split your view? One with shadows, one without together with your fill?

The only workaround I could think of is that you have a mesh set to “Top Surface Only” to cast a shadow on everything below grade. Instead of bits and pieces of shadow, you will have everything covered in shadows, no as clean as the white model but might be acceptable.

What I do if I want shadows on the Elevation drawing is to generate a straight on 3D view of the side you want, marquee the view and copy just the shadows without outlines. I then paste it onto the Elevation, move them over to the side enough to clear the elevation. I then group the shadows, delete the ones below grade and then move them back. The problem with this approach is that the shadows are static and you will have to repeat this if you change the model. It gets fairly quick once you have done it a few times.
