Visual Style of Hidden Objects

jcronin — Thu, 23 Aug 2018 12:55:24 GMT

The situation:

I have a grading plan that is a 3D solid, when I plot the drawing I have created with the grading plan referenced into it I will be plotting using the Legacy Hidden plot style. i do not want to show the grading plan as it has many edges, but I want anything below (having a lesser Z value) to plot as a hidden line. I can achieve this with the following system variable settings-but not without having to include the grading plan. Any suggestions? Flatten, flatshot, drawing view is not an option.

System variables:

DISPSILH = 1
OBSCUREDLTYPE = 2

Hi @jcronin,

I think I understand what you are asking but to be certain, can you share a drawing where you have this set up?

I assume that a section plane or live section won't work for what you are trying to display.

See attachments-imagine the rectangle as a grading drawing and the cylinder as a conduit/pipe. Negative on the other two options either. They will only be plan drawings also, i did include a ortho view in the example just for clarification but were only talking about the left most viewport set to legacy hidden plot style. I cant use the exact files that I am working with for copyright issues but the idea here is exactly the same. Thanks John.

Hi @jcronin,

Just a quick thought before I dive into this, would changing the grading solid to color 255,25,255 work?

Negative, plotting using monochrome.ctb. (screenshot from plot preview)

Hi @jcronin,

I set the color to 25,255,255 and then set the visual style to Wireframe in the left hand view.

Here are my plot settings:

I believe that your able to do that because the "plot with plot styles" box is unchecked, mine must be checked. I could not recreate what you did.

Hi @jcronin,

Try my version of your file. I have applied a pagesetup with the plot settings (with the Plot Style selected). I have attached the resulting PDF output also for your review.

I see what you did now, it worked. It worked on my drawing as well! Brilliance and thanks a million! The whole time I'm thinking system variable somewhere or unloading a reference.
