A good time to start practicing with other software, just to be sure...

Which one? Nothing is like SketchUp. And all the scripts/plugins and models. Jeez! Count me as VERY worried, too.

But then, we still can stay with the current version and ignore any updates. At least, as long we don't run into bugs, that is.

Best would be someone skilled starting to recreate SketchUp as OpenSource. Full API compatibility for models and plugins. Same functionality. All the same. Just from another code. But then, there may be fckng software-patents prohibiting this. I feel bad.

I have created quite a few models. That was with v6 and, possibly, earlier. Now I use v8 (v7 does the same in this regard). I do not find myself at home in the application anymore. Did the process of simple drawing change? I don't seem to be able to draw a circle from a point on the surface (created with the cline tool) to short before the edge of the rectangle . The construction point is 3mm from both rectangle edges at the corner and I want to draw the circle with a radius of 2.8mm. It either snaps to the edge or nothing happens.

Same for the cline tool (a well known plugin). Once I was able to freely place the points on the surface of the rectangle. Now I am not anymore. You need this, when you want to define a point on the surface as the center of a circle, or so. You construct a point per line of the cornering edges and from there you go to the surface then, using straight lines.

I then want to place some construction points (using CLineTool by Jim Foltz). First I create the + points, from there I can define the * point, which will become the center of a circle, representing a drill hole.

Not possible! I can't get to *.

Please help. Thanks a lot!
