Hi, I have a question regararding the API, I am fairly new to the API.

I am using VB Visual Studio .Net Express to write an external application for Solid Works 2008. When I want to draw a very small rectangle into a sketch (by small I mean merely 5mm) it doesnt draw it at all. Strange thing is that if I run the same code in the internal vb editor, it does draw it.... If I change the size to 50mm it does draw it from the external program... Strange...

Has anyone encountered this problem before? Please let me know what I can do... The entire program would be useless otherwise...

Thanks!

hello,

do you use SketchManager::AddToDB =true ??

I didnt use AddtoDB.
So I tried this:

Dim d = 0.0015
mStandard(2).Select2(True, 0)
mMod.InsertSketch2(False)
mMod.SketchManager.AddToDB = True
mMod.SketchManager.CreateCornerRectangle(-d, d, 0, d, -d, 0)
mMod.InsertSketch2(False)
mMod.ClearSelection()

mStandard(2) is reference to the Front Plane Feature.

Strange thing is, that the above code works down to d=0.0016, but d=0.0015 it wont draw... This is really annoying... Any idea whats wrong? Could it be because of some kind of snap function or grid that is on?

Cheers,
Ben

Set this system option:
swApp.SetUserPreferenceToggle swSketchInference, False

This disables snapping at all.

Yes, this behaviour is usually the internal snapping. However, this should cause no issues if you add the sketch entities directly to the database. To achieve this you have to set AddToDB for the sketch manager or SetAddToDB for the modeldoc like Jens said.

Maybe you should set AddToDB to True before inserting the new sketch, but I havn't tried that.

Bye,
Stefan

Hi,

I tried the following:

        Dim d = 0.0015
        mMod.SetUserPreferenceToggle(swUserPreferenceToggle_e.swSketchInference, False)
        mStandard(2).Select2(True, 0)
        mMod.InsertSketch2(False)
        mMod.SketchManager.CreateCornerRectangle(-d, d, 0, d, -d, 0)
        mMod.InsertSketch2(False)
        mMod.ClearSelection()

And a call to both:

  mMod.SetAddToDB(True)

as well as

  mMod.SketchManager.AddtoDB = True

both before and after mMod.InsertSketch2. Same result. It draws the rectangle when d=0.0016 but not when d=0.0015.

Most unfortunately, d=0.0015 is the actual dimension I need... Any other ideas why this is happening?

Thanks again,
Ben

Not using this:
mMod.SetUserPreferenceToggle(swUserPreferenceToggle_e.swSketchInference, False)

Use this (system option!!):
swapp.SetUserPreferenceToggle(swUserPreferenceToggle_e.swSketchInference, False)

mkkk,

it works! thank you very much... I guess I only need to call this function to the Application object once at the beginning, right?

Thanks again and again,
Ben

Yes, but it would be better to save the current state by SldWorks::GetUserPreferenceToggle, set the needed state and after work reset to the old state.
