OrthoGraph Architect for iPad

OrthoGraph had been available for creating floor plans on-site with portable Windows CE devices, but due to the aging WinCE platform and significant increases in the computing power, they have written the software for iOS, and so now recommend the iPad version only. (The company is continuing to port features from WinCE to iOS.)

During a Webinar last week, Orthograph managing director Laszlo Toth emphasized that this is a survey tool, and not CAD software. You use it to create floor plans, add information, and then export it to a CAD program.

 

Tutorial

Here is how it works:

  1. Enter initial data into Orthograph running on the iPad, such as a room on level 1, and the units, metric or Imperial. Specify wall thickness and indicate which sides of the walls are being measured, inside or outside.

  2. With your finger, sketch an initial outline of the room. The software converts your sketch into straight lines; if necessary, edit the initial outline, such as to change walls to curves (arcs).

  3. The software guesses at the initial dimensions; when you correct one dimension, the software updates the rest of the room's initial measurements. See Figure 1.

  4. Manually correct the other dimensions; you can enter diagonal (corner to corner) measurements, too. A green '+' indicates fully surveyed areas, a red '?' means one or more dimensions are missing. In this way, you cannot forget to take all measurements!

  5. Enter the height; edit the data sheet of walls, such as color, material, and override thickness. It generates data, such as area, perimeter.

  6. Pick points to located doors and windows; for doors, you can swipe the direction of its opening. You can add room furnishings from the built-in library, such as chairs and tables, and then you can edit their properties.

  7. You add additional rooms in the same way, and then attach them by locating their connecting doors.

Figure 1: Sketching the room layout (left) and then adding dimensions (right).

 

You can insert point clouds and scanned documents as backgrounds, scaled and with variable transparency. As before, you trace over the image with the finger, and then add accuracy.

 

Getting Drawings to CAD

When done, you upload the drawing to Dropbox in JPG, PNG, and SRVD (Orthograph) formats. To get SRVD files into other CAD packages, you use translation software, which runs on desktop computers (not the iPad):

The DWG and ArchiCAD translators are free for five rooms, $100 each for up to 50 rooms, and $500 each for an unlimited number of rooms.

 

Future Plans

This is just the first release of Orthograph for iPad. The company already has plans to add freestanding walls, and to record lines and sketches -- rather than always converting them to walls. 3D visualization of walls and objects is planned, as well as the ability to coordinate with multiple inputs from several surveyors.

 

It will allow you to customize templates and objects in the library. A translator for Revit is forthcoming.

 

Q&A

Q: Can the program recognize curves from your finger sketches?
A:
No, but you can bend segments after the initial sketch by adding arcs or vertices.

 

Q: How do you take the measurements?
A:
Distances must be entered by hand; Apple's implementation of Bluetooth does not connect to Bluetooth laser measuring devices, such as from Leica.

 

Q: Will this software be available on Android tablets?
A:
In the long term, yes.

 

Q: How does the software determine the initial lengths of walls?
A:
It makes a guess; once you specify the actual length of the first wall, the remaining walls are changed to match.

 

Q: How many simultaneous objects does the software handle? How many rooms per project?
A:
There is no limit. OrthoGraphic uses a tree structure to support very large surveys, such as 240,000 sq ft.

 

Q: Can the iPad version be used on its own, or do you have to also purchase the desktop software?
A:
iPad could be used on its own, but you need a desktop computer to further process the data. All the CAD converters are standalone programs that run on a desktop computer.

PTC Meets With Journalists (Part ii)
During the media day with Parametric Technologies Corp, staff explained that many improvements were made in basic tools like sketch-based features in Creo 1.0: extrudes, sweeps, anything created from a sketch. For example, select a planar face, hit extrude, and then start sketching on the face; if no face is selected, then you can select a sketch to immediately create an extrude feature.

 

Looking Forward to Creo 2.0

In Creo Parametric 2.0, new drag handles adjust just the related dimensions, and not any linked dimensions; this carries out automatic parametric unlocking. Hold down Alt to select to geometry with which to reference a constraint, such as parallel to an edge.

 

While assembling components, the 3D dragger will limit dragging to respect degrees of constraint as assembly constraints are applied. For example, a concentric constraint allows a part to be dragged only along the axis.

 

When you choose an edge or a face, a rectangle pops up with data about the feature. You can copy and paste the data, and then use it to build a parameter, meaning, design intent. (This feature was always available, but was hidden deep in the old menu system.)

 

Cross sectioning is improved through the use of a drag handle for dragging the cross section to revealing more or less of the model. A 2D window pops up to show the face on section view.

 

Flex modeling was already in 1.0 and now in 2.0 is improved. It is meant for making edits towards the end of the design process, such as just before manufacturing. "Flex" is the name for direct editing done inside Creo Parametric.

 

Pattern (array) recognition finds patterns in imported models, with black dots locating members of the pattern. This lets you change the pattern, such as from twelve to five polar copies. Pattern propagation lets you edit one item of the pattern, and can specify that the change be propagated to the other items; as this happens, parametrics get applied to the imported model.

 

Q: How does the history tree deal with the changes created by Creo Direct?
A:
As of Creo 2, the user has the option of collapsing a number of modeling changes into a lump of geometry -- although this action loses the parametrics. The collapse capability is for when the user has taken a model into Creo Direct and done a bunch of geometry-based modeling on the model. Much of that work will be recorded in Creo Parametric as features. If the Parametric user doesn't want those features, then they can be collapsed into a single piece of geometry.


This option is not provided in Creo Parametric's Flexible Modeling extension. We are assuming that parametric modeling users would modify the original parametric model to achieve the results they want. For a many different reasons they are, however, unable to do this, and so they use Flexible Modeling to perform geometry edits on the model, which is done as a parametric feature.

 

Q: Competitive systems struggle with dealing with topological changes.
A:
We are working towards making significant topological changes. CoCreate is the best at that, and we are getting close to what CoCreate can do.

 

Creo Layout

Creo Layout is the name of PTC's AutoCAD-displacement program, as product management manager Raphael Nascimento showed us. It is software for drawing in 2D and editing sections imported from 3D programs. Creo Layout and Creo Parametric are one-way associative from 2D to 3D: changes in 2D show up in linked 3D models, but not the other way around. Because Creo uses a common database, there is no "importing" or "exporting."

 

In Layout, you can specify items as "public" or not, allowing you to use the program as a scratchpad. Only public entities are visible back in Parametric. "2D and 3D each have their advantages, and so we want to synchronize them, something that is not possible with AutoCAD," PTC told us. "Layout does not compete against AutoCAD on the basis of features, but rather on integration." Nevertheless, PTC plans to expand the capabilities of Layout over the next several releases.

 

Q: But isn't 2D CAD dying market?
A:
We have tried for decades to convince customers to only use 3D Parametric modeling. But we have large customers with hundreds of seats of Pro/E and AutoCAD, because they still do certain kinds of tasks in 2D.

 

PTC now offers a 30-day demo of Creo Parametric 1.0, delivered on a DVD after registration, at http://www.ptc.com/product/creo/free-trial/parametric/. For another review of the PTC media day, read "Creo 2.0 is Near" by Evan Yares at http://www.3dcadtips.com/creo-2-0-is-near/

We interviewed Christopher Scotton of ClearEdge3D a year ago at http://www.upfrontezine.com/2011/upf-688.htm over his software's ability to convert point clouds into objects automatically. Today he wrote me with an update: "We have been perfecting a series of new algorithms that can extract nearly every pipe in the scene -- in testing we've been pulling out more than 90% of the pipes and no other extraction tools comes close to that." Some intelligence is being extracted, such as ODs and lengths. http://www.clearedge3d.com

CAD Tips

Q: Have you evaluated DraftSight recently? I would appreciate hearing your opinions -- especially regarding the API (LISP & .net) available in the Professional version."

     - B. T.

 

A: The free version is mostly like AutoCAD LT. The command names and system variable names are different in DraftSight, but there are aliases to make most of them the same as AutoCAD.

 

I haven't used the Pro version, and I have no experience with .net, so I wouldn't be able to tell you how/if it works. The workaround is to download the demo version of Graebert ARES Commander Edition, which I believe has similar APIs as DraftSight Pro. The list of features is at http://www.graebert.com/en/cad/ares/65 and the download page is here http://www.graebert.com/en/cad/ares.
