Any method to generate an intersect between 3D and 2D Object?
image 01
I am trying to generate an intersection between solids and a 2D object (mesh or surface)
the result should be something like this:

Anyone know if possible? And How?

Do you mean
a) a permanent line entity is created
b) or just a snappable temporary line of intersection
c) and whether the latter is visible rather than just found by the mouse?

A temporary option across a plane can be achieved using a sectionplane with clip display on.
In this mode you can use entity snaps to snap to points on the section plane.

Using sectionplane and sectionplanetoblock I have this result, I lost the transparency result.

I'm trying to obtain this result in a future (but with colors):

a), I expected lines and their own separate hatch with transparency or different color like this:

b) any method is acceptable, but I try to create separated hatches.
c) i wish created intersections, but each intersection with different transparency level as a separate and independient object.0 -
If that is lighting intensity there is software for that, but it may not be a CAD program. and yes has a cost.

Way back, Microstation's way to snap to a line of intersection was a command to first create an actual line entity, then it could be snapped to.
I remember (but can't find) discussion here of whether such an entity could be created and viewed dynamically changing while the intersecting objects were moved (so that the moving line could itself be snapped to something, thus determining the final position of the intersecting objects). The answer was 'too resource hungry', of course, better done with parametrics.

you can also use the SECTION command to generate sections betwen solids and an arbitrary plane (flat surface or mesh) , the result are regions which can have transparency and material assignments…

Thank you to everyone. Section command work for me. Others can give similar results but I need to edit
others questions:
1) I found to generate 3D Subtract and Intersect (commands) are too complicate, because I need to copy multiple times the same 3D solids. Is there any method to generate Subtract and Intersect between all selected solids?
2) same question that 1), but with 2D objects (in this case Region Object). Is there any method to generate Subtract and Intersect between all selected 2D Objects?
3) Is possible to do 1) and / or 2) with AutoLisp / VisualLisp for linux? (no COM) example: activate lisp, then select 3D / 2D objects, then the autolisp should do intersection and substract with transparency detection, the transparent level for intersection objects should be minor while more solids are intersected.0 -
I use Dialux Evo, but in each simulation in similar spaces appears different results. Also, Dialux and Relux are closed source, and is not clear which parameters use. And in both are very slow to work.
,,, I calculated manually lights in LibreOffice Calc (LO Calc), and I found better results and faster work that working with Dialux and Relux.
The workflow that I try to design will work in any software included BricsCAD.0 -
Your questions :
1. In order to generate the Intersections between all selected solids you can use the INTERFERE command !
You can use one or two selection sets to check for interferences…
: INTERFERE
Select first set of entities or [Nested selection/Settings/selection options (?)] <Nested selection>:
Select second set of entities or [Nested selection/Settings/checK first set/selection options (?)] <checK first set>:
etc.
2-3 Use the attached Lisp function to Interfere 2 selection Sets of Regions
Load the lisp routine using the APPLOAD command and call with the INTERFEREREGIONS command exposed by the routine…

This is an update for the INTERFEREREGIONS command !
The command now behaves exactly like the native INTERFERE command for 3D Solids.
There are now the options to select two interfering sets of regions OR one set, either the first or the second one (effectively ALL regions selected !)
In the screenshot left ALL Regions selected (green and cyan), on the right 2 sets selected (green interfering cyan and vice versa)
