VectorDraw IFC Library is an add-on to VectorDraw Developer Framework (VDF). You must have a current VDF license to purchase IFC Library.
VectorDraw IFC Library License is added to the VDF’s subscription, and the expiration date is the same as the VDF’s. The License for both VectorDraw Developer Framework and VectorDraw IFC Library must be renewed in subsequent years in order to continue to use the software.

One license is required per VectorDraw Developer Framework (VDF) Subsciption (not per developer). Each license includes a c# project that contains the source code of a wall custom object and provides the ability to import and export to IFC format.

Please note: Every VectorDraw client has only 1 expiration date which is the date of the initial purchase. If you delay or pre-buy a renewal , or if you add additional licenses to your subscription the expiration date remains the same and the newly added licenses alter the renewal price.

For example if you initially purchase a 4 Developer VDF License on January 1st 2020 you would need to purchase a 4 Developer VDF Annual Renewal Licenses on January 1st 2021 to continue using the software.
If you then purchased a VectorDraw IFC Library License on March 1st 2020 it gets added to your VDF Licenses and you would need renew all Licenses on January 1st 2021.
