Draw hull lines .dwg

The version of SU is 15.0.9349
The file where I worked on the post above is posted

The problem occurs when I want to merge the two groups with key union
I solved using as the end circumference of the tubular big to create the conical end.

Thomas, I just sent in a bug splat report:
In short:
I Made no changes! to geometry sizes like the cone error size.
I just moved the cone group into place to contact the tube group’s back face.
Then I used the ā€˜Union’ tool to unite the cone group with the tube group.
SketchUp stopped/closed and I got a bug splat. I hope the report ended up with Trimble SketchUp (has your name included). For at first the report wasn’t send properly, I got an error while sending. But I think it finally got through anyway.

Win? OSX? SU2015? Did you enter any info?

Thank you - I reproduced it! I’ll file an internal issue.

I still need your help, I have to build the frame of the windows on the front windshield.

I tried several times to build as the previous frames but degrees and inclinations does not come out good work.

What do you suggest to do a good job.

Enclose drawing of what I do

thanks
Nicola

@thomas: I didn’t enter any, only the steps to reproduce.
I used Win7 and SKetchUp Pro 2015 version 15.0.9351 32-bit

I’d use Fredo’s Tools On Surface extension: SketchUp Plugins | PluginStore | SketchUcation
It let you perform offset operations across the surface.

And after you have an outline of edges onto the surface, you can use Fredo’s JointPushPull to extrude all faces in one go… :wink:

Great for the suggestions I could make the front frame.
Now I have another problem similar to the above when SU crasch.
I have to create the walkway on the bridge, I created an area and I extruded downward.
I then created a group and I finally created a single solid with key union and SU closes unexpectedly crash.

This time where am I wrong?
I enclose working files and images

thanks

I noticed that every union of groups with the boat SU crash.

If I make a union with the solids out of the boat is correct, but if you use the boat group to join other objects SU closes

How can I see where is the problem, on the previous post you can download the file

thanks
