Please help me: `deterministicIds` DO NOT in ALL ids returned by `qeverything()`

jiahao_lee103

I want to convert deterministicIds(in feature list) into query and then parse it. The conversion code is as follows:

body = {

    "script":

        "function(context is Context, queries) { "

        "   const _ = qEverything();"

        "   const all_q = evaluateQuery(context, _);"

        "   var target_q = -1;"

        "   return transientQueriesToStrings(all_q);"

        "   for (var i = 0; i < size(all_q); i += 1) {"

        "       if (\"%s\" == all_q[i].transientId) {" % tid +

        "           target_q = all_q[i];"

        "       }"

        "   }"

        #parse ...

        "}",

}

res = self._api.request("post", "/api/v10/partstudios/d/" + did + "/w/" + wid + "/e/" + eid + "/featurescript",

                        body=body)

res_ = res.json()["result"]["value"]

But I found that the deterministicIds in chamfer or fillet cannot be found in this way, so I can't resolve the edges or faces referenced by chamfer or fillet operations. Why does this happen? How should I solve this problem?

Below is a snippet from the feature list, which contains the entity IDs referenced by chamfer and fillet.

If you want the queryString referenced in features, it maybe simpler to get the list of features & extract the queryStrings from the features. The transientQueriesToStrings method will return the deterministicIds.

Dear @Paul_J_Premakumar ,

Thank you for your prompt response and for sharing your insights on the approach.

I tried the method you mentioned but failed. My code is as follows:

  body = {

      "script":

          "function(context is Context, queries) { "

          "   const _ = qCompressed(1.0,\"%B5$QueryM5S12$disambiguationDataA1M2S12$disambiguationTypeS13$ORIGINAL_DEPENDENCYS9$originalsA1C0M5Sa$entityTypeBa$EntityTypeS4$EDGESb$historyTypeS8$CREATIONSb$operationIdB2$IdA1S11.6$FGOtGUnjjNTgkPK_0wireOpS9$queryTypeSd$SKETCH_ENTITYSe$sketchEntityIdSc$KfxfNm3nASbMR4C6S4$FACER6R7R8CbA1S11.9$FNJb7sDs7ut4Qgu_0opExtrudeRbSa$SWEPT_FACE\", makeId(\"FkAc0mg4NYcOSCa_1\"));"



          # "  canBeQuery(_);" # true

          "   const q = evaluateQuery(context, _);"


          "   return q;"

          "}"

  }

  res = self._api.request("post",

                          "/api/v10/partstudios/d/" + self.did + "/w/" + self.wid + "/e/" + self.eid + "/featurescript",

                          body=body)

evaluateQuery(context, _) return an empty array:

"result": {

    "btType": "com.belmonttech.serialize.fsvalue.BTFSValueArray", 

    "value": [], 

    "typeTag": ""

}, 

So my questions is:

Question

In feature list, the entities content is like:

{

    "featureType": "chamfer", 

    "btType": "BTMFeature-134", 

    "name": "Chamfer 1", 

    "featureId": "FkAc0mg4NYcOSCa_1", 

    "parameters": [

        {

            "parameterId": "entities", 

            "btType": "BTMParameterQueryList-148", 

            "nodeId": "fuIh17TZu52EKemJ", 

            "queries": [

                {

                    "queryString": "query=qCompressed(1.0,\"%B5$QueryM5S12$disambiguationDataA1M2S12$disambiguationTypeS13$ORIGINAL_DEPENDENCYS9$originalsA1C0M5Sa$entityTypeBa$EntityTypeS4$EDGESb$historyTypeS8$CREATIONSb$operationIdB2$IdA1S11.6$FGOtGUnjjNTgkPK_0wireOpS9$queryTypeSd$SKETCH_ENTITYSe$sketchEntityIdSc$KfxfNm3nASbMR4C6S4$FACER6R7R8CbA1S11.9$FNJb7sDs7ut4Qgu_0opExtrudeRbSa$SWEPT_FACE\",id);", 

                    "deterministicIds": [

                        "JHW"

                    ], 

https://cad.onshape.com/documents/35472159f025cdc9f3dceadf/w/e697a0ab884317ecffe02f25/e/0be68b867fee1010f3e8d1f6

The id in qCompressed is a variable. I set it to the corresponding featureId through makeId(taking the above code snippet as an example, I set it to the featureId of Chamfer 1). Is this correct?

I look forward to hearing your thoughts on this and thank you for your time and assistance!

Hi jiahao_lee103,

1. The "deterministicIds" i.e. "deterministicIds": ["JHW"] in the response , is the result of evaluating the query in the queryString. You can directly use it, instead of re-evaluating the queryString.
2. If you want to evaluate the queryString to get the id, you need to pass in newId() in the call to qCompressed for example, with this document : https://cad.onshape.com/documents/fa6695405b76e3f6952469e8/w/e0a3a95fbf60f2254d393c77/e/2abc17b0c7e832bb5fbd57ea, this code works

 { "script": "function(context is Context, queries) { return transientQueriesToStrings(evaluateQuery(context,qCompressed(1.0, \"%B5$QueryM6S12$disambiguationDataA1M2S12$disambiguationTypeS13$ORIGINAL_DEPENDENCYS9$originalsA1C0M5Sa$entityTypeBa$EntityTypeS4$EDGESb$historyTypeS8$CREATIONSb$operationIdB2$IdA1S11.6.6$F8yaanKhR4f29nQ_0sketchwireOpS9$queryTypeSd$SKETCH_ENTITYSe$sketchEntityIdS9.3$rectangletopR4R5R6R7S7$isStartFR8CbA1S-c.7.9$extrudeopExtrudeRbS8$CAP_EDGE\", newId()))); }"}

» But I found that the deterministicIds in chamfer or fillet cannot be found in this way, so I can't resolve the edges or faces referenced by chamfer or fillet operations. Why does this happen? How should I solve this problem?

The reason for this is once the chamfer or fillet feature executes, the edges they reference are no longer present after the regeneration. Hence they are not returned by qEverything. The way to solve this would be to get the query, move the rollback ( https://cad.onshape.com/glassworks/explorer#/PartStudio/updateRollback) just above the feature & then evaluate the query at this state.

Thank you very much! @Paul_J_Premakumar Your answer has completely cleared up my confusion!

But I have one last question, can the same effect be achieved by updating feature with suppress=true?
