'Curves not planar' error message
Read 3893 times

I am running TCMac Deluxe v7.5.3 build 1103 64bit

I am trying to make solids from profiles. 

Sometimes it works fine but with some profiles I get the message 'Curves not planar'.  If I redraw the profile with a  multiline and join the ends I get the same message.  This only seems to happen with some shapes and I cannot work out what makes one work and another not.  One profile will always work OK but another will always give this error message.

All the profiles are just a collection of straight lines so this should be straightforward.

I have tried redrawing many times and the error is consistent - I have also tried 'join curves' and 'select chain' but nothing seems to make these certain profiles work.

I am using the 'Extrude Solid' tool trying to extrude 4mm in z axis.

Any idea what i am doing wrong and how to fix it?

Example attached

Not much hair left!

Hi Clive,
I've gotten tripped up on this in the past.

When you redraw your profile in Top View, make sure you check Workplane in your snaps, that should fix the problem.
You can see from the screenshot, the lines are not all all the same plane, causing the error message.

Best regards,

Darren

Hi Darren,

That is brilliant thanks.  I hadn't thought to look sideways at the parts - but it shows the problem very elegantly.  And your solution is so easy to implement.

Do you happen to know of a way of flattening an existing profile so it is just on the one (X/Y) plane?

Clive,

The fastest way I can think of is select all the lines, and in the Inspector enter the z axis for the needed plane and then "Apply". In the screen shot I set them all to 0.0.

Thanks for the additional info Mitch,
I'm always on the visual math side of the fence, didn't think of that one.

Darren,

The "Select Chain" answer you gave in another thread was much better than my reply! I don't think I have ever use that menu option, but I will put in my bag of tricks.

Enjoy

I need to hang out here with you guys more. So many tricks to learn. I've done some pretty cool stuff with TurboCAD Mac Pro starting with v5.1, but I've really just kludged my way through.

And the one in this thread has bit me more than once too. Nice solutions guys.

Thanks Eso!
Everybody uses the program in different ways, so it's always a learning experience here.

You're welcome to hang out with us.
