so far Ive been getting the hang of how to create the shell of the houses and now have begun playing with the inside especially cabinets. I tried to use the cabinet tool within plus spec design but unfortunately I wasn’t able to recreate accurate or identical cabinets to the ones we use therefore I created individual cabinets and brought them in as you can see. Now here is where I am having trouble. to create an accurate takeoff with cabinets I will need to state how much crown mold I will need above the wall cabinets per stick (formula is length of total crown mold/12/8= x sticks) How can this be done?
2.) next one is countertop sqft. for cabinets we use different countertops for the kitchen, secondary bathrooms and master bathroom. How can i separate these? also whenever I insert a sink into the countertop and cut it out can the formula take into account this and subtract that from the total?
CORNICE
There are three methods to add cornice to your model (depending on your desired result &/or workflow). Personally, I think Option 3 (maybe Option 2) will do what you need.
Option 1: Draw the cornice with the walls by specifying them in the Trim section of the Wall Tool.
Option 2: Draw the cornice using the Ceiling Tool & toggle them on/off for each side of the “ceiling” you draw. After the “ceiling” is drawn, click into the group & delete the ceiling skin. Note: Deleting the geometry is a manual edit, so it’ll get reverted if the geometry is edited again using one of our tools.
Option 3: Manually draw each length of the cornice using SketchUp tools, then use the Custom Estimation Tool to apply a cornice material so it estimates in the Takeoff. Note: Make sure to apply the cornice material each length since it’ll estimate as lineal. Tip: Draw the cornice profile & a path, then use the SketchUp ‘Follow Me Tool’ to create the lengths of cornice.
In the Takeoff, recipes can then be added which can link with the cornice material, equations/formulas can be entered, & more (regardless of which option above you use).
COUNTERTOPS
Similar to Option 3 mentioned above, I would recommend using SketchUp tools to create the countertop geometry (cutouts for sinks, etc. included), make the geometry a group & then use the Custom Estimation Tool to apply an estimating material to the geometry. Note: If the material you’re after isn’t currently available in the Custom Estimation Tool, you can add you own by using the create material feature. To do so, select a material then click on the Create Similar Product button & follow the steps.
