Driving Sketch Better than equation

Driving Sketch Better than equation

Driving Sketch Better than equation

(OP)
Do you know about those call driving sketch ?

RE: Driving Sketch Better than equation

(OP)
I believe they are sketches in which all dimensions are being stored.
All following features don’t have any dimensions.

RE: Driving Sketch Better than equation

That's a bit extreme, but overall not a bad modelling practice.  This is especially true in cases where persons other than the CAD modeler make most of the design decisions.

With new designs, I normally make one or two "control line" sketches.  For instance, the main profile of an extruded hinge will be a stand-alone sketch.  The first extrude feature's sketch will reference the control line sketch using "Convert Entities".  Later features reference the control line sketches instead of model edges whenever possible.

This may sound like a pain in the arse, but it saves a lot of trouble in the long run.  I find it's easier to manage changes in models when they are constructed in this fashion.

You think that is extreme check this out!
Now that you have those 3 driving sketches (top, front & write) you can create a design table that drives your driving sketches.
In other words when you want to change something you look only in one place your design table.

RE: Driving Sketch Better than equation

DT drive Dimensions, so if your sketches are controlled by dimensions, then the answer would be yes.

RE: Driving Sketch Better than equation

(OP)
Did you know that driven dimensions could be used as an impute values for a design table.

RE: Driving Sketch Better than equation

(OP)
I know, the goal is not to change them but it is to use them as impute value for your other parts. It means that you can drives a assembly by one part by using driven dimension in design table.

RE: Driving Sketch Better than equation

(OP)
I never said that the DT would be in the assembly.
I only use DT in parts.
