Go modify > Change Parameter

Parameter: Enable user to change dimension easily by editing on parameter instead of choosing different faces to change dimensions

Aware where is length, width and height

Edit certain specification like height,length, weight and thickness

Create new component, name "Front plate"

Create sketch on the ZX plane

Create a rectangle with dimension of "length" and "height"(dimension use follow parameter)

Extrude the image with distance of "thickness"

Next, create tabs on both sides and bottom, create rectangle(whixh is the tabs),dimension using the parameter(length of tabs on width is wtabs or length of tabs on height is htabs) by thickness

Extrude cut the tabs with dimension: thickness

Using rectangular pattern, enter the number as parameter(nltabs or nwtabs) and distance is (length - length of tab*3) or (width - width of tabs*3)depends on which dimensions use to refer

Create a new component on the right face of the front plate

Create rectangle and colinear to constraint the side and dimension the width

Create a circle and hole size dimension of "hole" (parameter setting) and dimension between 2 circles is at least 4 mm, extrude with "thicknes" dimension

Using same setting on desgin front, similar steps, add tabs but now only do on the width, or bottom face of the right plate will do

Extrude and rectangular pattern to form the tabs

Using the face of the front side and the other end of "Right" face to create midplane.

Mirror Front component using plane created and combine cut the design on "Right" component

Repeat the step to create plane as reference point to mirror "Right"component

Create component at the bottom face of any component

Draw rectangle and dimension to have allowance on all sides，at least 5 to 10mm

Extrude the rectangle and combine cut the rectangle using other 4 components as reference(cutting tools)

Create component for making a cover

Offset plane from the inner back plane, offset a distance of 15mm

Create a rectangle and extrude with a dimension of "coverwidth"(parameter)

Create sketch on the side surface, sketch a rectangle and extrude out the as the attach join of the cover to the box

Create and using midplane of the cover, mirror the circular joint of the cover component

Box Design:
