GDL - Cylind & Elbow Contour Lines

Anonymous — Tue, 26 Oct 2010 02:37:52 GMT

Is it possible to get rid of the contour lines between the Cylinders and Elbow? or can you only control visible lines with PRISM_ ect.?
Is there a better way to do this?

Cylind and elbow do not have parameters for that. Try this one. I think it can do: Knee

I think if you use Grouping to add them together you can.
Otherwise use Prism for the straight parts and Revolves for the curved parts.

Yes Grouping does it.
Try this.

GROUP "one"
CYLIND 0.05, 0.025
ENDGROUP

GROUP "two"
ADDz 0.05
CYLIND 0.05, 0.025
ENDGROUP

result = ADDGROUP ("one", "two")
PLACEGROUP result

Actually doesn't seem to work if you group a cylinder and an elbow. works with two cylinders though.

There's always Trussmaker.

a=1 : b=0.2
k=0
s=0
n=36
winkel=30
rsl=24

hotspot 0,0,htspt
for i=0 to n
  put b*cos(360/n*i)
  put a+b*sin(360/n*i)
  put 1
  next i

if rsl>3 then resol rsl

revolve n+1, winkel, 1*0+2+4+8+16*s+32*s+64*k,

Are you sure?

a=1 : b=0.2
k=0
s=0
n=36
winkel=60
rsl=24

GROUP "one"
CYLIND 0.2, 0.2
ENDGROUP

GROUP "two"
ADD 0,-a,0.2
hotspot 0,0,htspt
for i=0 to n
put b*cos(360/n*i)
put a+b*sin(360/n*i)
put 1
next i

if rsl>3 then resol rsl

revolve n+1, winkel, 1*0+2+4+8+16*s+32*1+64*k,
get(nsp)
ENDGROUP

result = ADDGROUP ( "one", "two")
PLACEGROUP result

You can control the lines at the ends of the revolve with the masking values (ie 16 & 32) as Frank was demonstrating.

Yeah definately didn't work with Cylind & Elbow unless there is something im missing.

Will try with revolve. Thanks

Sorry Wardy - my bad
Half asleep this morning and forgot that you had specifically mentioned the Elbow.
You are correct this does not hide the end lines for the elbow.
Not sure why it works with cylinders but not with elbows - only graphisoft could answer that.

Personally I always try to use prisms instead of cylinders and revolves for the elbows.
This way you don't usually need the grouping as you have control of the masking values.

Here is a very simple spout.

CYLIND 0.005, 0.0245
ADD 0, 0, 0.005
CYLIND 0.040, 0.013
ADD 0, 0, 0.040
PRISM_ 7, 0.087,
0.008, 0.0, 11+64,
1.387778780781E-017, 0.0, 900,
0, 180, 4011+64,
-0.008, 0.0, 11+64,
1.387778780781E-017, 0.0, 900,
0, 180, 4011+64,
0.008, 0.0, -1
ROTz -90
ADD 0, 0.07, 0.087

REVOLVE 7, 180, 1*0+2*0+4*0+16*1+32*0+64*0,
0.008, 0.07, 1,
1.387778780781E-017, 0.07, 900,
0, 180, 4011+64,
-0.008, 0.07, 1,
1.387778780781E-017, 0.07, 900,
0, 180, 4011+64,
0.008, 0.07, 1
DEL 4

Yeah Thanks Barry, i did this particular object when i had just started scripting, have since looked at it and wanted to improve it. I'll replace the cylinders with Prisms and Revolve instead of elbow as you mentioned.
