We emphasize the importance of drawing full size when developing a CAD plan for a site. We use the measure tool to estimate the distance from a boundary to the footprint of a house and scale accordingly. Once our model reflects the real world measurements, we insert a block of a car and show that there is enough space to fit two cars into the parking area.
Just as lineweight of an entity can be set implicitly or BYLAYER, so too can linetype patterns. Here we change the linetype scale of a closed polyline so a hidden line shows. We then hatch the zone making sure that the correct layer is active.
We show how to clean up a ‘messy’ polyline imported from AutoCAD. We add point data and snap to the points in order to create a new polyline. The align dimension tool is then used to add dimensions to assist a construction team lay out the design.
It is best to adopt a light touch when applying hatching to zones in a landscape drawing. Too much hatching can overwhelm the design. We apply a grass pattern and a brick pattern to indicate the type of surface covering. The advantage of setting a border for a polyline shape is discussed.
Users new to CAD drafting often find managing lineweights tricky. Here we show the importance of the LWT switch in the status line, the value of controlling lineweight by layer settings and the need to take output sheet size into consideration.

We take a base plan in gCADPlus and write a DXF file ready for importation into SketchUp. A 3D SketchUp model is then constructed using this base data.
