Hi Rudl, it is possible to create a point object where a line and plane intersect by using the Construct > Curve > Isect command:



To do that, select both the plane and your line (it should be a regular line object and not a temporary "construction line"), and click that button and a point object will be generated at the intersection.

That command will generate curves where 2 surfaces or solids intersect one another, and also point objects where curves intersect other curves, surfaces, or solids.



> Is it also possible. to find out the point between a constructionline and a plane.

Not directly with the construction line itself, you need to draw in a regular line object which can then be selected and used as input into Construct > Curve > Isect.

In what way? Do you mean while drawing a point object? Yes - you can use construction lines in any "drawing" command where MoI is asking you to pick a point location.

No, when I want to move a point of a rectangle for example. I define one c-line and another and use the intersection; also an example.

Hi Rudl,

> No, when I want to move a point of a rectangle for example.

That's easiest to do using the Transform > Move command where you pick 2 points (basically the "move from" and "move to" points) to do the movement rather than the quick dragging method.

So turn on control points for your rectangle, select the point you want to move, then run Transform > Move, and then pick the "from" point snapped on to that control point you want to move and then for the "to" point you'll be able to set up construction lines then.

It's not so easy to use construction lines when you're doing the direct dragging instead because the drag happens so quickly with your mouse button already held down.
