Successful component creation relies on correct component positioning. This article will cover the reasons why components may be unavailable or may be appearing in incorrect locations.

Component is in the wrong location

If a component is appearing in an incorrect position in the 3D Render, the component is most likely in the wrong location in the component tree.

For vertical vessels, components should appear in the tree in the order they should appear on the vessel from top to bottom. For horizontal vessels, components should be in order from left to right. To move a component in the component tree, select the desired component and click the up or down arrow to the left of the tree.

If a head is still appearing in the wrong location after being moved in the component tree, open the head by double-clicking the component on the tree or by right-clicking it and selecting "Edit." Make sure the location specified on the General tab of the Head window matches the desired location.

Component is unavailable

If a component is disabled, the most likely reason is that you are attempting to add the component to an invalid location. Certain components must be added to a host while others can only be added to the vessel itself. Each new component will be added to the location selected in the component tree when it is created.

In the image below, a shell is selected; only components that can be added to that shell are available in the component menu.

Certain components can only be added to specific types of vessels. For example, the entire Exchanger menu is disabled if the vessel is not a Heat Exchanger. In the image below, only Saddle is available in the Structural menu because the vessel was created as a horizontal vessel with a saddle support.
