- Why do I get a message that says "No connection to the server."?
If you get this message intermittently, it's probably caused by a network glitch or a busy server. Restarting the app will usually fix it, although you may have to wait a couple of minutes. If you get this message all the time, your device is probably behind a firewall or connecting through a proxy server or VPN that filters data from the internet. You will then need to try and establish a clean connection.
- How do I import drawings into my app?
For the iPad version, Apple's email app and Dropbox and Evernote iPad apps allow you to touch an attached TechDraw file, launch TechDraw, and import the drawing. For the Android version, most email apps and Evernote and Dropbox provide the same functionality. Files may also be transferred between the iPad and Android versions of TechDraw and a consistent 1024 x 1024px canvas drawing area is maintained in versions 3.0 and later.
- Can I import equations I've created in MathTech into TechDraw?
Yes. For both the iOS and Android versions, TechDraw is a superset of the functionality in MathTech and can import files created in that app.
- When I touch a shape, it doesn't show as selected.
This is caused by the current layer being different than the layer assigned to the shape. If there are no shapes selected you can determine which shapes are assigned to which layers by selecting each layer in turn - the shapes asigned to each layer chosen will then have their bounding box displayed.
- Why doesn't the app operate in landscape orientation?
Version 3.0 and later supports landscape orientation and is a free upgrade from the original app store where you downloaded the app.
- Do I need to be online to use TechDraw?
The full version of TechDraw can be used offline except for the export of data or images. TechDraw Free requires online access for all functions.
Can I use my drawings in other applications?
With the drawing you want share showing on the canvas, select "Share drawing image..." from the menu, then choose how you'd like to share an image of your drawing. Version 3.0 and later produces a consistent 512 x 512px image of your drawing canvas. You can store it in the pictures directory of your device, email it, or use any of the other sharing mechanisms. You can then use the shared image as part of a presentation or other document.
