Hi Steve, a smaller number is definitely more efficient in file size, but unless you're getting up to like 10,000 of these offsets you probably don't have to worry about it.

Many of the later on operations that are going to be performed on your objects (like meshing or toolpath generation) will generally follow the shape of your object and not automatically become more complicated just because there are more control points in the curves. Instead they will be more complicated in areas of high curvature, not just automatically where there are a higher number of points.

It is particularly not convenient to have a whole bunch of points if you want to edit the shape of the offset curve by tweaking control points around, similar to how you would have edited the very original curve. But for the thing that you're talking about, you probably won't be doing that. Typically for the kind of thing that I think you're doing you would focus your effort on editing the original curve to make it shaped right and not want to edit the resulting offset curve, it is just a thing that is calculated from your edited one.

I'd think that you could probably just not worry about that particular thing for your case...

Yes, point taken Michael

After all it is going to be relatively quite a small file.

Thanks again

The "sheet" has no thickness.
All I did was to lower the standard 3d letters just a fraction through the sheet and then did some booleans and trim stuff.

EDIT--No booleans--all cut and trim!

Hi Michael,

>>You may be interested in this method of doing a tapered style extrude:
http://moi3d.com/forum/index.php?webtag=MOI&msg=941.5

In relation to this thread I was just wondering now that we have direct math input in MoI, you mentioned that angle input is in radians, the formula you used in that particular thread to create tapers, is 'Offset dist = Height x Tan( angle )' which is used often in mech eng and nice and easy to input into MoI, but to convert to radians which is: degrees X pi/180 it's a bit annoying is there any way to change the angle input in MoI to degrees ?

Thanks

Hi Danny, re: math expressions angle input in degrees,

Yeah I think that makes sense since this area is for typing stuff in.

It is pretty easy to tweak that and I have set this up now for the next beta. All the trig functions (tan, sin, cos, atan2, atan, asin, acos) will now take or return angle values in degrees with the next beta.

If you do need to use radians for some reason, the radians versions are all still present with an underscore preceding them, like: _cos(PI) that keeps radians input still easy to use if someone feels the urge to type in values in radians... :)

Thanks Michael,

Also, it's good that you kept the radians side of things, I do sometimes have that urge to calculate things in radians, usually standing on my head drinking an ice cold coke through my nose :D


Cheers

Thanks Brian

When you say "the standard 3d letters"

did they come from inside MoI or outside?

Steve

Steve
Yes. The standard letter text in the solids.

BUT
Am I pe-empting you with this question about fillets?
Image and file.

Brian

Brian,

I'm embarrased to say that I had never noticed the letters before!

It just proves that you see what you want to see!

Yes that is the sort of look I am after with the filleting...I've continued this as a new topic.

Steve
