I bought the app and I have immediately subscribed for a year! This is what I
am looking for ever since. Especially the intuitive structure of the software
is intriguing to me.
We are glad you like it
my 1st question: How do I move in 3d space? So far it seems that I am dependent
on the grid.
One finger pan will orbit the camera around a center point. The center point can change if you have an object in the front of you. The two finger pan will move the camera left/right and up/down. The up/down direction depends on the grid indeed.
Can I work independently of the grid, e. g., set a point above a
triangle in order to draw 3 lines to the 3 corners of the triangle and create a
pyramid with 3 sides?
Currently you can't. Currently sketches are limited to the grid and to faces.
What is the easiest way to set this point?
The usual workflow would be to create the sketch on the grid, then transform it to the appropriate position with the transform/translate/rotate tools.
How do I connect all four points?
Currently that's not how you would create a pyramid. I would create a cube, then cut out triangular extrusions from it. But soon we will add a draft tool, with that you will be able to draft shapes.
2nd, how about:
extending an existing line. I wish I could select and press the pen to
FREEZE the line and then extending it in either direction by moving the pen.
Currently we are working on HUGE improvements in the sketching engine, we will add constraints, and customizable construction planes.
connecting two independent points in 3d space. E.
We may add 3D curves in the near future, but we don't have an ETA for that.
g., I wish I could select the first point by e. g. pressing the pen on it
to FREEZE it (so it can be snapped), then go to the second point (but how to
snap it?) and draw a line from there to the first FROZEN/snapped point without
needing any grid.
Yes, that's one of the features that we will add together with the constraints feature.
