project2{4}

[Paalanen]

Hello everybody!

project2{4} again, sorry: Seems I cannot avoid the projected filltype overriding the cut filltype. I.e. I can't control the two fills separately, as I can the pens:

methodx=3+32+512
partsi=1+2+4+8



project2{4} 4, 0,
0, 0,
0,
methodx, partsi,
12, ! cut fill
1, 0,
0, 0, -SYMB_ROTANGLE,
cutPen, SYMB_LINETYPE, ! cutLinePen, cutLineType

0, ! projected fill overrides cut fill !!!
0, 0,
0, 0, 0,
projectPen, SYMB_LINETYPE, ! projectedLinePen, projectedLineType

Any comments appreciated!

Hello and thank you very much for your response!

Here's a simplified version:

3d:

!status = 1+8+16
status = 1+16 !-Not through
status2 = 5

side = 2 : n = 15

add side/2, side/3, side/2
cutform{2} 4, 1, status,
0, 0, -1, .2,
.1, 0, status2,
0, 0, 900 + status2,
0, 180, 4000 + status2,
0, 180, 4000 + status2
del 1

put 0, 0, 0, n, 1,
0, side, 0, n, 1,
side, side, 0, n, 1,
side, 0, 0, n, 1

cprism_{2} 1, 1, 1,
nsp/5, side/2, get(nsp)

2d:

Actually, another thing is bothering me, trying to find workarounds: The basic project2-command draws the cutform shapes with a solid line regardless of a line_type-command (,that otherwise works):

line_type test_line
project2 3,270,2+32

Hi,

you need to set status j2 in CUTFORM (generated cut polygons will be treated as normal polygons), otherwise the circular surface of the cut will be a cut polygon, and PROJECT2 treats it as such, regardless its position in space.

With PROJECT2{3} cut surfaces can only be created by cutting the model with cut commands. PROJECT2{4} also cuts the model on its own, but inherits cut surfaces from different cut commands.

You can use SECT_ATTRS with PROJECT2{3} to change cut edges' line types.

[Paalanen]

Thank you very much once again. Status j2 in CUTFORM got indeed rid of the cut surface (fill) from the circular shape. However, using PROJECT2{4} the outline of it remained cut (,dependent on Cut Line Pen setting in the object's CUT SURFACES settings). I.e. it does not seem to be possible to control neither the pen nor the line type of the cutform projection. Using PROJECT2 and PROJECT2{3} with SECT_ATTRS the problem is similar; one cannot control the line type of the cutform projection - it remains solid.

Am I missing something or could this be called a bug / characteristic?

[Peter Baksa · Accepted solution]

Yes, it can be called a bug.

If there are no other cut lines in your projection, you can use flag 32 in the method parameter to override the cut line attributes.

Thanks again Peter. I guess I'll go looking for a workaround... I guess there's no way of knowing wether Graphisoft will fix this "bug" or not?

Kind regards!
