how to edit the sketch and hence edit the extruded feature using API?

Dear all,

Now i am working on Solidworks API. What i want to do is to modify the
feature dimension. In solidworks interface, we can see that if the user
want to edit the dimensions except for the depth information of the
feature, the user have to access the sketch and edit the sketch to
update the feature finally.

So i think it should work in the same way in Solidworks API, is it?

Now what i do is want to modify the coordinates for the sketch points
of the sketch to edit the sketch.
But a problem emerged, now i can access the chosen feature's sketch and
read every sketch point in it. After getting the sketch point, i want
to use the funciton of pSketchPoint->SetCoords(modifiedcoord[0],
modifiedcoord[1], modifiedcoord[2], &retval); to modify its
coordinates, but unfortunately it did not work, the value for retval is
FALSE. don't know why.
for the coordinates i read from the sketch point and the coordinates
which is revalued to the sketch point are transfered between the sketch
coordinates system and model system and i have checked these values
which are correct.
Do i need to add functions such as pModelDoc2->editsketch()...and
pModelDoc2->pModelDoc->EditRebuild3 (&retval); before and after the
codes to access the sketch and reset its coordinates?

thanks so much

cheers

Hi,

I hope the following will help you.

Before you can set new coords to the sketchpoint, the sketch must be in
editsketch mode (AFAIK). I am also working with the Solidworks API and I
do it in the following way:

//first select the sketch by its name, if not selected yet
pModelDocExtension->SelectByID2( ... )

//put the sketch in "edit mode"
pModelDoc2->EditSketch();

//make your point changes
pSketchPoint->SetCoords ( ...);

//leave the "edit mode"
pModelDoc2->InsertSketch2(VARIANT_TRUE);


Frank.

Dear Frank

It works, thanks so much
my codes cannot work, mainly because i did not select the sketch before
setting its editing status
thanks again
Have a good day ahead
