Hello all,

Anyone aware of any protoolkit api functions to update dimensions into the cad model and regenerate it. FYKI, i have fetched dimension from cad active model using dimension visit api call and saved into a text file already.

// Init a Dimension by model, int dim_id
status = ProModelitemInit(model,dim_id,PRO_DIMENSION,&dim);

//Change it dimValue is a double
status = ProDimensionValueSet(&dim,dimValue);

//Regen
status = ProSolidRegenerate(model, BitMaskRegenOptions);

    @FV_01 Thanks for the response, one doubt above that, how to use ProModelitemInit or ProModelitemByNameInit to find a dimension in an active model ? since i will be loading a file containing dimension to be edited with its name , ID and value
