Hi there, is there a way (native or with a plugin) to select an intersection point of 2 lines that are not in same plane? I want to e.g. draw a column that fits within a wall on a ground floor plan and also in a wall on the first floor running perpendicular to it. So far i have achieved this by drawing inference lines on the lower plan and shifting them up to the upper plan and then drawing within the intersection points. But it will be real helpful if i can draw directly on the top plan (using top view) and select the intersection points with the line below. Technically, the intersection doesn’t exist and is more of projected point.
Yes. Inference the end point of one of the lines you want to use as a guide, hover momentarily of the end point to load that into the inference engine memory. Then move to the second line and slide along it until you get the inference indication that references the previous end point.
@endlessfix I have looked at it closely. The inferencing technique that you showed works well when the two lines are drawn parallel to the green and red axis, however not for lines drawn at odd angles. Would you have any solution for that?
Perhaps you could use guidelines in a vertical orientation to create the intersections you need.
@DaveR i think i will have to create a guide plane (perhaps with ‘workplane’ plugin), as i wouldn’t know where to start the guideline. Not sure if it is any quicker.
Maybe you would need to add a “guide plane” No extension needed. Just draw a rectangle using one of the existing edges as a reference.
Use the pencil tool. Start at the end point of one line, start drawing along that line and hold down shift to lock the pencil to that vector. Then reference the end point of the second crossing line and click to end pencil drawing, if you have your preferences set up to continue pencil drawing you will be set to draw a vertical line from there. If not you can easily find that created node and start again from there. This method also works with the tape measure to set a guide point at the intersection if you would rather.
That method assumes 90 between lines, if not and you really want a guide plane, perhaps Pushline could help.
Thanks you. I believe setting up the guide point for perpendicular lines in this way is the best solution. For odd angles i will keep the Pushline tool in mind.
