Hi @ all,

I have a problem with the Thicken-Tool, when I create a solid body from a lofted surface. Sometimes it is successful but very often it fails. There seems to be a dependence with the width of the guide curves and after many tries I can repeat the failure.

What I have done:

- Creating 3 or more curves for a body, asymetric rounded to all directions
- the first curve is laying flat, the others are standing upright
- I have signed 3 construction lines, line A / A' is only for orientation, B/B' // C/C' is the distance-area where the the Thicken-Tool is running fine, when the endpoints of my "base-line" are between this lines
- when my "base-line" is more width, so that the endpoints are between A/A' and B/B' than the Thicken-Tool fails.
- C/C' is only the smallest distance I have tested, desired is a width, greater than B/B' to A/A' - at the moment not possible -
- the Lofting-Tool is always working fine !

I can't see any reason for this reaction of the tool, perhaps somebody has a solution or knows the reason for this dependence between the width of the "base-line".
Possibly there are existing more dependences but I found out only this one.

I have attached some pictures and vcp-files in different stadium of drawing.

Best regards

Reminder!!!

Nobody knows ... ???

@ Tim
A solution ist urgent for my projekt!

I have drawn a very complex part of a motocycle but I can't use it without thicken the surface to a solid.

Hello Horst,

The spline you have laying flat is the one causing the skin to have an issue when thickening. Can you change the spline slightly?

Hello Horst,

The flat spline located wrt to the sections is causing the surface slope to crunch up. In the attached file you can see this when you offset the surface. If the thicken tool fails, this is usually the first thing I do to figure out where it may have failed.

Would it be possible to create an extended surface and then trim at Z=0? This might give the smoothest surface that can be thickened as in attached.

Tim

Hi Tim,

thats the solution. I have tested it and it is running fine!

Many thanks
