I have created a model of yacht hulls on SolidWorks using the boundary surface function. When I tried to create a drawing of it to get an orthographic display, the boundary surface does not show up on the drawing, I only get the end drawings used to make the surface. Does anyone know how to get round this?
As soon as you make a feature using a surface, the surface is considered reference geometry and will not show up in the drawing unless you explicitly import it. If you roll your model back to a point before Boss-Extrude1, your boundary surface will appear in the drawing as expected. So, in order to make it appear when the model is rolled forward, you need to use the Insert....Model Items menu command and select Surfaces in the Reference Geometry category to import the surfaces:
Then your drawing will look correct:
