A required resource was ... (not availible?) running an api program.

Hello,

I've been doing some api programming. At the time I'm making a program
simulating a milling curve in space. At the beginning of the program
SolidWork run normal. After a while (app. after creating 25 sketches)
SolidWorks slows down, and becomes even slower every time it creates
more sketches. After having created 75 sketches, (it is always 75)
SolidWorks send you a messagebox saying: "A required resource was "
and that's it. It doesn't say what kind of problem SolidWorks have.
After clicking the OK button, SolidWorks run pretty fast again. Until
sometime it just exits my program without any message. I presume some
sort of cache or something like it force this problem. It is not the
UNDO list. I flush it without any differences.

Have someone of you had the same problem? If so, what did you do to
resolve the problem. If not, do someone have an idea?

Best regards,

Ulf

 

I'm no pro at this, but sounds like a memory leak. It may be
SolidWorks or it may be your routine. You may want to review to make
sure objects are being handled correctly, as a starting point.

How are you dimming your objects?

Make sure any and all objects are set to NOTHING at the end of your
program before it closes. This includes all document objects, feature
opjects, application ("swApp"), etc.

 

Hi,

first of all I want to mention that I write my programs in C#.
I do not allocate any memory other than my local variables which are
only "doubles" and only 18 of them.
Below you will see my code:


iSwApp.SetUserPreferenceToggle((int)swUserPreferenceToggle_e.swSketchAutomaticRelations,
false);

iSwApp.SetUserPreferenceToggle((int)swUserPreferenceToggle_e.swSketchInference,
false);

modDoc.Extension.SelectByID2("", "FACE", 0.3, 0.1,
0.1, false, 0, null, 0);
modDoc.InsertSketch2(false);
modDoc.ViewZoomTo2(pU0x-Math.Abs(p0x-pU0x), pU1y
+Math.Abs(p0y-pU1y), 0.05, pL1x+Math.Abs(p1x-pL1x), pL0y-Math.Abs(p1y-
pL1y), 0.05);

// Centerline
swLineCenter =
(ISketchSegment)modDoc.CreateLine2(p0x, p0y, p0z, p1x, p1y, p1z);
swLineCenter.ConstructionGeometry = true;
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
p0x, p0y, p0z, false, 0, null, 0);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
p1x, p1y, p1z, true, 0, null, 0);
modDoc.SketchAddConstraints("sgFIXED");

// Topline of slot
swLineTop =
(ISketchSegment)modDoc.CreateLine2(pU0x, pU0y, pU0z, pU1x, pU1y,
pU1z);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pU0x, pU0y, pU0z, false, 0, null, 0);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pU1x, pU1y, pU1z, true, 0, null, 0);
modDoc.SketchAddConstraints("sgFIXED");

// Bottomline of slot
swLineBottom =
(ISketchSegment)modDoc.CreateLine2(pL0x, pL0y, pL0z, pL1x, pL1y,
pL1z);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pL0x, pL0y, pL0z, false, 0, null, 0);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pL1x, pL1y, pL1z, true, 0, null, 0);
modDoc.SketchAddConstraints("sgFIXED");

// Enabling automatic sketch relations

iSwApp.SetUserPreferenceToggle((int)swUserPreferenceToggle_e.swSketchInference,
true);

iSwApp.SetUserPreferenceToggle((int)swUserPreferenceToggle_e.swSketchAutomaticRelations,
true);

// Inserting the Arcs
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pU1x, pU1y, pU1z, false, 0, null, 0);
resultArc = modDoc.CreateTangentArc2(pU1x, pU1y,
pU1z, pL1x, pL1y, pL1z, (int)swTangentArcTypes_e.swForward);
modDoc.Extension.SelectByID2("", "SKETCHPOINT",
pL0x, pL0y, pL0z, false, 0, null, 0);
resultArc = modDoc.CreateTangentArc2(pL0x, pL0y,
pL0z, pU0x, pU0y, pU0z, (int)swTangentArcTypes_e.swForward);

// Creating a FeatureCut.
modDoc.FeatureManager.FeatureCut(true, false,
false, 0, 0, 0.01, 0.1, false, false, false, false, 0.018, 0.018,
false, false, false, false, false, true, true);

As you can see I make featureCut of a slot. This stops after 75 times
with the message.
