Introduction

3 Chris Price Cadway Design Methods to keep your Models Happy The Power of the Massing Tool Forgotten tricks of the Roof Tool Shape Editing of Floors/Roofs Using tools & thinking outside the box Site Tools Structural Tools Links & Groups Limitations of Revit Family Creation Overview

4 Chris Price Cadway Design What degree should I model to? Ask yourself the following questions: –Is this seen in more than one view? –Is modelling this going to improve my documentations buildability? –If I dont model this is it going to cause co-ordination issues between views that would benefit from being modelled in 3D? –How large is the model Im working on? –Could I make use of this in future projects? Answering these questions should help you make the correct judgement.

5 Chris Price Cadway Design One hand should always be positioned over the TAB key. Take time to correctly set layer functions of Walls, Ceilings & Roofs. –Ignore the titles & concentrate on the numbers –Generally the most exterior finish layers I create as layer 5. –This can save a lot of frustration!

8 Chris Price Cadway Design Make Use of Stacked & Compound Walls where appropriate: –Stacked walls are for more complex situations as shown below: How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

9 Chris Price Cadway Design Make use of your Model for showing smart representations of Roof Overhangs, Foundations or even future phases in Plan. There are two methods to do this: The Linework Tool. How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families Limitations: –New Roofs or new lines in roof sketches need to be manually added again using the linework tool.

10 Chris Price Cadway Design Overlaying Views How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families Limitations: –For roofs they need to be set to wireframe so there well be excess linework. –This can be removed using the linework tool & Invisible lines.

11 Chris Price Cadway Design In Revit you should place approximately and then refine positions using the temporary dimensions. Use generic elements to begin with and then use Select all Instances to easily swap out elements at a later stage. You can also use the Reload family in the project browser and actually select the family you wish to replace it with to swap the family out in one step… How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

12 Chris Price Cadway Design Use Generic Massing families in pre-design/conceptual studies. How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

13 Chris Price Cadway Design Use grids and levels to establish and maintain relationships. Remember most of the modelling tools in Revit are dynamic. Always check your options bar… Minimise locked relationships in a project. Only do so when there is a specific reason. Pin reference information to avoid accidental bumps… Attach walls, columns to roofs, floors and beams. Let Revit maintain these relationships for you.

14 Chris Price Cadway Design Create a line based family to model egress paths as suggest by Steve Stafford. How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

15 Chris Price Cadway Design Try using floors and walls for joinery, doors for cupboards etc… How to keep your model happy General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

16 Chris Price Cadway Design Leverage Data from previous projects… –If youve done a detailed amenities layout with fixtures, why not save that data out for later use. –We utilise numerous cut & paste projects for pre-setup stairs, railings, walls and typically layouts.

17 Chris Price Cadway Design Utilise massing for complex forms by using the by face options for walls, roofs and floors. Check this out The power of the Mass General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

18 Chris Price Cadway Design How about using the Mass tool to define a complex building envelope and set back requirements. –Use the co-ordination monitor to check for conflicts!

19 Chris Price Cadway Design People often forget that you have an option for segmentation on curved segments in Roof Sketches. You can use multiple slope arrows combined with slope defining lines! Forgotten tricks of the Roof Tool General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

20 Chris Price Cadway Design In Revit 2008 we saw the release of this fantastic new function of roofs and floors. What weve used it for so far: –Tiling with a topping slab with falls to wastes. Shape Editing, Not quite like Mystique from X-Men General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

21 Chris Price Cadway Design In Revit 2008 we saw the release of this fantastic new function of roofs and floors. What weve used it for so far: –Sloping Structural Falls that need to match street levels. Shape Editing, Not quite like Mystique from X-Men General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

22 Chris Price Cadway Design In Revit 2008 we saw the release of this fantastic new function of roofs and floors. What weve used it for so far: –Site Works –Just to name a few possible uses for this tool… –Get to know it! Shape Editing, Not quite like Mystique from X-Men General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

23 Chris Price Cadway Design Try creating wall mounted railings for sunscreens. (Great when curved walls are involved). Using embedded curtain walls for strip glazing and finding at corners the wall isnt cut correctly? –Use a wall hosted generic model void to cutout the unwanted part. Curtain Walls/Glazing & Railings and their hidden skills (thinking outside the box) General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

24 Chris Price Cadway Design For quick, highly customisable screens, battens use curtain walls… Curtain Walls/Glazing & Railings and their hidden skills (thinking outside the box) General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

25 Chris Price Cadway Design For Smaller Projects which can afford to be more detailed: –Use the sloped glazing system to model the ceiling grid system with modelled T sections or a standing seam metal roof. –Or use curtain walls for pre-cast concrete construction showing joints etc. Curtain Walls/Glazing & Railings and their hidden skills (thinking outside the box) General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

26 Chris Price Cadway Design Understanding their limitations: –You cannot have sloping pads. –You cannot have vertical faces on your topography for retaining walls. –Paths/Driveways with complex falls can now be created using point edits. However, you must use the linework tool to remove the vertices from each view. Refer to this post on AUGI for a great workflow given by Jerry (jetisart) –http://forums.augi.com/showthread.php?t=63962&page=2&pp=10http://forums.augi.com/showthread.php?t=63962&page=2&pp=10 General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families Site Tools – What Site tools?

27 Chris Price Cadway Design Remember the trim tool works on beams! Always host roof framing (ie: rafters) to the roof and give it an offset to allow for purlins and cleans. Columns can attach to beams. Modelling purlins, girts or joists? Use the structural framing system tool. So whats holding up your building? Time to add some structure… General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

28 Chris Price Cadway Design Accept that for the moment Revit Architecture leaves a gap between beams. Fix this with detailing. So whats holding up your building? Time to add some structure… General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

29 Chris Price Cadway Design In Revit 2008 groups and links are now interchangeable. This makes this decision less critical Use the following outlines of benefits and limitations to decide on per project basis whats most appropriate to you: Groups –Can be tagged and quickly manipulated in the host file. –Can interact (to an extent) with surrounding geometry not part of the group. –Can exclude elements from specific instances of a group. To link or group, that is the question General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

30 Chris Price Cadway Design Links –Better for file size as all information is stored in the other file. –Tags have to be applied in the other file and the views linked across (not possible for sections & elevations) –Somewhat more reliable as they do not interact with elements in the host file. It is best practice to use non-hosted families when grouping elements. To link or group, that is the question General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

31 Chris Price Cadway Design Unfortunately, no software is perfect and it does have its limitations. Getting to understand what these are makes your working relationship with Revit much more relaxed. Maintain efficiency. Give yourself a time limit on each modelling task. Stair & Ramp tools have a number of limitations: –Curved Monolithic Stairs with smooth underside anomolies. –They do not join to floors. –The sketches have issues when overlapping themselves. –Stairs going down from the current level dont display correctly. What? Revit has limitations! General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

32 Chris Price Cadway Design Railing Tool –Baluster/support locations sometimes are just too varied to position with this tool. What? Revit has limitations! General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

33 Chris Price Cadway Design Family creation should be about leveraging as much data as possible. Quality not quantity. If it repeats it should be a family (Not In-place) Nested sub-components setup with swappable parameters allow for the maximum flexibility. Lets go raise a library of happy families General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

34 Chris Price Cadway Design Nest detail components for highly detailed view specific elements. Add control arrows to all directional families. Constrain all geometry in families via reference planes Flex Flex Flex Give reference planes strengths & labels Use Transfer Project Standards to copy materials between families. Arraying elements? Use nested families and constrain them by their origin point in all 3 vertices for both the two defining elements of the array. Check out my blog for a detailed explanation on this. Lets go raise a library of happy families General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

35 Chris Price Cadway Design Its more efficient to create families as non-hosted first. Avoid in-place families. Set your origin (placement point) to a logical locations. Use line based families for complex linear objects. Lets go raise a library of happy families General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

36 Chris Price Cadway Design Modelled something in-place and now discovering you need it to repeat around your model? –Edit the in-place family, select all the geometry, copy to the clipboard and paste into a new family of the same or appropriate category. Lets go raise a library of happy families General Massing Roof Tool Shape Editing Outside the Box Site Tools Structural Tools Links & Groups Limitations Families

37 Chris Price Cadway Design The most important thing I think I can leave you with is: MODEL TO A DEGREE THAT ALLOWS YOU TO CO- ORDINATE EFFECTIVELY AND EFFICIENTLY. Sometimes its great to have a play and test Revits limits by modelling to minute detail. However, youll soon find that your computer will slow to a halt and the model will become very frustrating. ENJOY IT!!! I DO Any Questions? Conclusion & Questions?
