[REQUEST] Automatic drawing of vertical lines

Chris Fullmer

ok, script released here:

301 Moved Permanently

(www.sketchucation.com)

It does not remember your settings from one SU session to another. I kept getting a lot of errors in trying to implement read_default and write default methods. And I also couldn't figure out how to encode in hex. THat is a new world to me and I didn't find anything useful (or that I understood?) in the ruby rdocs either. I think I'm done for the night, but maybe tomorrow if I get a chance, I'll try it again. Thanks for all the help everyone! Hope its useful Panga and others,

You want to convert some data to HEX values?

Chris Fullmer

Yeah, how would I go about doing that?

Chris

thomthom

Do you want to convert numbers to hex? Or do you want to take a string and convert each byte into a hex number?

Chris Fullmer

I have no idea. I think the string idea (unless its harder to implement).

thomthom

Why do you want it as hex anyway?
Hex can only be numbers, only way to convert a string is to take each characters, get the character code which is an integer, and convert that into hex values.

I'm just wondering if hex numbers is what you want. If you want to store data to disk then you will want to store it as binary instead, as that's how data is stored anyway.

Pick a name (a key) wisely, like fullmer_linetool_length and store the value in a hex encoded value for best portability on both platforms. You might encounter a known bug if you don't encode a length value. (I don't remember right know if it is a dot, apost, quote or blank that causes issues on Windows.

He recommended using hex so as to not store it as a normal string since there is a chance I'll encounter a bug. I suppose binary would work? Just as long as I can get away from a normal string,

hm... ok, you might want to probe Todd as I'm not 100% sure about this.

But converting from String to Hex-String to String, I think can be done like this:


# Pack the string to a hex string
# return value is an array with one entry
arrayData = "Hello World".unpack('H*')

Since arrayData is an array, you want to store arrayData[0].

Then when you load the string, you have to wrap it into an array again:


# storedDataString is the string you loaded
arrayData = [storedDataString] # This creates an array with the storedDataString


# Convert the Hex String back to a String;
myString = arrayData.pack('H*')

Let me know if that made any sense at all.

Chris Fullmer

Yup, that made sense (surprisingly, I'm sort of dense at times). Thanks very much Thom, I'll play with that when I get back to that part of the script. Currently trying to figure out how to average the normals of 2 planes to find a middle normal. Not having much luck so far

I think this will work:


vector1 = face1.normal
vector2 = face2.normal
vector3 = Geom;;Vector3d.linear_combination(0.5, vector1, 0.5, vector2)

Chris Fullmer

Thanks Thom. I had tried using that earlier and it did not produce what I thought I was looking for. Seems to be working just great right now. Thanks!
