Drawing an apex

Step 1

	- Open the drawing Drawing an apex.dwg
	- If the Context Modeler is not yet open, then click on the icon Context Modeler
	- Click on the button
	- Choose HEA from the list of section types
	- Select the profile section HEA240
	- Activate the button Apex
	- Make sure all the other context buttons are deactivated, these were possibly still active for the previous exercise!
	- In Context Modeler, click on the level symbol in case it is not yet active
	- Choose Apex for the top level
	- In Context Modeler, click on the level symbol in case it is not yet active
	- Choose Eaves for the bottom level
	- Move the cursor between two columns without clicking. We see that Parabuild suggests other slopes for the rafters that are not connected to the levels that we activated. The levels that we choose are suggestive. To force the levels we need to use the magnet function .
	- Activate the magnet button for both Top and Bottom levels
	- Now move the cursor to the highest point in the middle of 2 columns, and click the left mouse button to draw the apex.
	- Do the same for some more apex rafters - Then press <Enter> to end the command
