General Discussion / Re: Construction Lines
« Last post by Andy H on Today at 08:43:53 AM »
I've no idea what you mean by 'nice construction lines?'

Assuming you mean a TC construction line, and not just some 2D that you use as a basis for drawing 3d.  Then when you create a construction line, TC usually automatically creates a layer called $Construction.  You can turn visibility on / off the same way you do with any other layer.  For example in design director if you version supports that.

General Discussion / Re: How to share the program?

If you have an older version of the program, why not give him that.  As long as you delete the older program from your computer.  And if you chose an older version that your current version can 'Save-as' to, you can still share files.

To protect your property. You could always draw up a signed agreement saying he must delete and return the older version within so many days. that is if you wish the program back afterwards.  For me - it would depend on whether the person was a friend, or just a work colleague.

As far as I know the above is perfectly legal for versions prior TC 2019. (I don't know about 2019 / 2020.

How do we make nice construction lines?

That we can turn on and off?

For Dummies explanation needed.

Thanks!

Under no circumstances.  Your license, which you acknowledged to have read and agreed to when you installed the program, states one installation on one machine and a copy of the program for backup should your PC fail.

The idea of a simple standalone .stl to .stp converter is deceptively seductive but a practical impossibility for any .stl that's been produced from a model with a notionally curved surface.

Not necessarily.  The vertices depicting an edge in an STL file are spot on, with the lines being approximations.  Therefore, re-constructing a circle using TurboCAD's Circle by 3 Points tool would be accurate.  Deriving a curve from a series of vertices is also feasible if the conversion utility uses a bit of Artificial Intelligence.

Here's what I meant, Jeff:  consider an internal hole in an .stl that's designed to accommodate a fastener.  It should give clearance for the fastener, the facets are arranged so that the material closest to the notional axis of the hole is at the mid-point of a facet, ie the vertices are not on the edge of the hole, the mid-points of the edges are.  In the case of an external fillet, the notional cylindrical-section fillet may interpolate with the vertices of the .stl triangles, or the designer might have intended that the .stl could be smoothed by removing the high points of the facet to make a true cylindrical section.  If the .stl's vertices interpolate with the edge or slice plane of the cylindrical section, smoothing it will make the cylindrical surface minutely undersize.      Unless these sorts of notes are carried with an .stl, the nuance is lost.    That's one of the reasons that the Microsoft-led consortium is allowing provision for that sort of detail with the .3mf format.  Another point is that all 3D kernels work to tolerances, and you alter the tolerances, how accurately the facets represent the curved surface, when you change the ACIS settings in TC.  The tolerances mean that the vertices are within a designated distance from the true surface, but they can't all interpolate with it. 
This can be recognised to some extent with AI, but no AI algorithm can achieve a perfect result.

Thankyou Kevin and Murray.

I think I must look for things under the names an engineer would use, rather than by their geometry.

I'd probably make more progress if I use TC more often, as I use it to design the things I want to make, but more often "design" them by rule-of-thumb and a few rough sketches in the workshop instead. When I do design on the screen first, I use 2D drawings because I need dimensioned 2D drawings in the workshop.

A 3D model of something simple enough for me to draw might show me what it's meant to look like, but not help me make it because it is not dimensioned and gives foreshortened proportions. I have seen professional drawings that give all the machining information orthographically, and include a small 3D image in the corner to help the machinist visualise the work-piece; but that is beyond my level. 

 I don't suppose I drew that pump in the most efficient way at all, and I could do it only because the drawing's elements are symmetrical in some way in themselves or to each other. I still find most of the basic 3D concepts incomprehensible.

Hello,
I have been instructed to train a new person on using TurboCAD and so I to share a copy of the program I use with him so he can practice and work on his own computer.

is there a way of installing the program on both computers at the same time?
If so how?

Thank you in advance.

General Discussion / Re: Pipe bent around cylinder
« Last post by Don Cheke on May 29, 2020, 07:07:13 AM »
You will need to make a minute flat on the top of the tube where you can place a bend line and then use the bend tool. You will need a left and right bend at the desired radius. After the bend you can remove the flat with the facet edit tool.

Hi,

how do I get this tube bent around the cylinder? Can you help me?
